How to Buy a Cell Phone

রবিবার, মে ৩১, ২০০৯

With hundreds of handsets to choose from, it can be tough to find the right one. Here's what you need to know to dial up the perfect phone.

These days, smartphones get all the buzz, but the vast majority of handsets sold in the U.S. are actually feature phones: camera phones, music phones, rugged phones, messaging phones, or just plain voice phones.

Unlike smartphones, feature phones are a matter of "what you see is what you get." They don't receive magical software upgrades or run thousands of additional apps, as does the iPhone, for example. That doesn't mean they only make calls, though you can find phones that only make calls, if a basic phone is what you want. But most feature phones include some combination of a camera, a basic Web browser, e-mailing and text messaging apps, and music and video players.

Feature phones are typically less expensive than smartphones. They're available in a much wider range of shapes and sizes, and on a broader range of plans, including prepaid options. Monthly service fees for feature phones are generally cheaper too, which can make a multipurpose feature phone a good bet.

Ready to find your phone? Here's what you should consider before you start shopping:

First, Choose Your Carrier

Because all the national carriers sell a wide variety of phones, choosing your service provider should be your first move. Here's a quick rundown of what each of the primary U.S. carriers offers:

AT&T boasts nationwide coverage and a terrific selection of phones, particularly for texting. But some folks, especially in the Northeast, complain that AT&T's coverage isn't all it's cracked up to be when it comes to reliability and quality.

Cricket and MetroPCS are new "unlimited" carriers that offer much lower rates than their competitors and don't require contracts. But they aren't available everywhere, and they have a somewhat limited selection of phones.

Sprint is relatively inexpensive, and offers some neat media services and a solid high-speed network. It also has the most open approach to third-party apps, running the best e-mail software and letting its subscribers add a wide range of Java applications to their feature phones.

T-Mobile offers cutting-edge phones at relatively low monthly rates and enjoys a reputation for good customer service. But its nationwide coverage isn't as complete as AT&T's or Verizon's.

Verizon Wireless is famed for its excellent network quality and good customer service. Its prices, however, can be higher than the competition's, and the carrier is typically slow to offer new handset features, like 5-megapixel cameras. But when it comes to voice quality, many Verizon phones excel.

Virgin Mobile is a nationwide prepaid carrier that uses Sprint's network but can undercut Sprint's rates. Virgin has relatively few phones on its roster, and those it does offer are mostly low-end.

You may also see unlocked phones on the market that work with GSM networks such as AT&T and T-Mobile but aren't sold by the carriers. These handsets are often imports. Because they're generally more expensive than carrier-approved-and-subsidized phones, few are sold in the U.S.

Next, What Are Your Feature Priorities?

Because feature phones do almost everything, you should decide what capabilities you need or want most. Start narrowing down your choices by first ranking the five major categories of features in order of importance: voice, messaging, camera, media playback, and Web/GPS/games/miscellaneous. Once that's done, you'll be able to concentrate on a filtered-down selection of feature phones.

If you're big on text messaging, you want to focus on messaging functionality. If you've got a small child, a camera is probably important. If you want to ditch your iPod, keep an eye out for good media features.

Since it's a given that you want your calls to sound good, you may feel you should focus mainly on voice rather than other features. You don't need to worry too much about that. The vast majority of phones sold today have solid voice capabilities. Paying attention to the other features you like, and then double-checking to make sure the phone you choose delivers on voice quality, makes it easier to sift through a long list of handsets


What to Look for: Voice

Reading reviews and trying out a phone before you buy it are the best ways of gauging voice quality. Most phones fit into a broad middle range of reception and sound quality. But you can still find phones that are uncommonly loud or have a lot of "side tone," that is, the feedback of your own voice in your ear (which can help you avoid yelling into the phone).

If you're primarily interested in voice and you're looking at AT&T or T-Mobile, focus on 3G phones. Those carriers' 3G networks offer superior voice quality to that of the 2G networks. The major downside is that AT&T and T-Mobile 3G phones have about half the battery life of 2G phones.

Important voice features to look for include no-training voice dialing, Bluetooth headset support, and a standard (2.5mm or 3.5mm) wired headset jack.

Yes, there are still super-simple phones out there that basically only make calls. The Sanyo PRO 200 on Sprint and the Samsung Knack SCH-U310 on Verizon Wireless are two high-quality voice-only phones.

What to Look for: Messaging

Texting, e-mail, and IM capabilities are showing up in more and more phones these days. If you intend to text often, get a plan with unlimited text messaging—it'll likely save you money in the long run. The best phones for heavy messaging have full QWERTY keyboards, like Verizon Wireless's Samsung Alias 2 SCH-u750 and AT&T's Pantech Matrix C740. You may also want to check to ensure that the phone supports threaded texting, a feature that groups together all text messages from the same sender. The Alias 2 supports threading, but relatively few other phones do.

Don't expect e-mail or IM on feature phones to give you a full smartphone experience. Feature-phone e-mail programs typically download your e-mail in text-only mode, without attachments, and feature-phone IM programs often won't let you access your AIM buddies. Sprint's e-mail program, on handsets like the Samsung Rant, is the best of the bunch, supporting multiple accounts and some attachments.

What to Look for: Camera

The great thing about a phone with a camera is that you always have it with you, so you end up photographing moments you would have otherwise missed. Camera phones are becoming as good as low-end digital cameras, in many cases taking print-worthy photos.

If you're interested in taking shots with your camera phone at all, don't settle for less than 2MP. Keep an eye on reviews to see which phones take washed-out, compressed-looking photos and which take bright, clear shots. It's harder to find a good video phone than a good camera phone. If you want to post your videos online or burn them to DVD, look for a phone that takes 320-by-240-pixel videos, at 15 frames per second or better.

A few camera phones we've seen really stand out. The Motorola MotoZINE ZN5 and Samsung Memoir SGH-T929 on T-Mobile take 5MP and 8MP photos, respectively. The ZN5 has very little shutter delay. The Memoir takes somewhat better pictures, but you have to wait for them.

What to Look for: Media

If you want to get rid of your iPod, your best bet is one of Verizon Wireless's phones with V CAST Music with Rhapsody; these sync with the powerful Rhapsody music program on Windows PCs. Otherwise, look for the many phones that sync with Windows Media Player. Mac users are pretty much out of luck for syncing music on feature phones—you'll have to drag and drop your songs onto a microSD memory card.

You also want a phone with a 3.5mm headphone jack, so you can listen to your songs with standard music headphones. If you get a phone with a 2.5mm jack, or even worse, a proprietary one, you'll need a clumsy adapter to use quality headphones. As an alternative, look for a phone that supports stereo Bluetooth wireless headphones. Verizon's LG Chocolate 3 VX8560 is one example of a top-notch music phone, with a standard jack, stereo Bluetooth support, and access to Rhapsody.

Feature phones typically don't make very good video players. They often can't sync video with PCs and don't come with software to convert video into the often-obscure formats they support. (If you're a bit of a hacker, you can force your video into a phone-friendly format.) Look for a phone with a larger screen for video watching, like the LG Dare VX9700 for Verizon.

What to Look for: Web/GPS/Games/Etc.

Some phones have decent browsers that display most Web pages; others only have basic WAP browsers. If you want to surf often on your phone, you may want to consider Sprint, since the carrier will let you install the third-party Opera Mini Web browser on its devices. Most current phones come with some variety of for-pay GPS capability—but be sure to get a handset with a loud speakerphone so you can hear the directions. Phones can play games, too. Verizon's LG Versa VX9600, for example, is a great choice with its optional dedicated game pad.

And for the accident-prone, some phones, like AT&T's Samsung Rugby or Verizon Wireless's G'zOne series, are even ruggedized or waterproof.

How to Get the Best Price

Once you've made your handset decision, it's time to head to your carrier's store, right? Maybe not. The best deals you can find on feature phones are almost always online. Five places to look:

1) Your carrier's own Web site will likely have prices that are considerably lower than what you can find in a brick-and-mortar store. And you can often find online-only instant rebates.

2) You can find amazing deals on Amazon.com if you're switching carriers. You may have to send in a mail-in rebate form, however.

3) and 4) Wirefly.com and LetsTalk.com are reliable, competing cell-phone stores with their own exclusive offers.

5) Finally, true cheapskates should look for used phones on eBay. Especially if you're hoping to spend under $50 without signing a new contract, you can often find great deals on last year's models

How to creat a science blog

শনিবার, মে ৩০, ২০০৯

The World Wide Web has changed the world by providing the cheapest information sharing network ever seen. And the development of blogging software, now powerful and free to use, allows anyone to share their thoughts instantly with anyone else in the world with an Internet connection.

That personal link is at the heart of blogging. The very word blog comes from web log, in other words a diary. Just as diaries can have many forms, so can blogs, but they tend to differ from conventional media in their focus.

What to blog on — and how?

You might be a scientist who wants to blog about your own science or issues facing scientists. You might be a science journalist wanting to report on science in a way that is different to the more conventional publications that you write for. Or you may be a wannabe political commentator, monitoring science policy and its potential impacts. All of these could come under the umbrella of science blogging, which follows many of the same rules as other types of blogs.

First, choose a subject that you are both passionate and knowledgeable about. Keep it focused. Choose too broad a topic — physics, say — and you will find it very hard to add something unique and interesting to the web that will attract readers. The risk of picking too narrow a topic is far lower — there may be few people in your organisation who care deeply about moths, for example, but there are likely to be many more around the world.

What you choose to blog about — and how — will also depend on your intended audience, be they scientists in that field, scientists from other disciplines or the general public.

One of the very best, and most successful, science blogs is called Pharyngula, written by biologist P. Z. Myers, who works at the University of Minnesota. He describes it as "evolution, development, and random biological ejaculations from a godless liberal", and it has been a powerful pro-science voice in the creationism debate in the United States.

The blog is one of many excellent blogs on ScienceBlogs. The site's founder, Adam Bly, aims to make science as central to culture as politics or the arts, and ScienceBlogs shows how the engaging and conversational style of blogs can help make that happen.

So how personal should a blog get? Here's a rule of thumb — if you start writing about your pet dog, you have probably crossed a line. But anything short of that is not only fine, it's essential. Your personality is what will make your blog stand out from others, and will bring you that all important connection with your readers.

This can be uncomfortable for academics and professional journalists, who spend their careers sheltered by the use of the third person (I remember struggling to begin sentences with "I" when I started blogging). But persevere, you will quickly adapt and find it liberating. If you don't, then what you are writing isn't a blog, it's an article.

How often?

How regularly should you blog? The short answer is every day. Readers want to feel the blog is alive, and frequent posts show this. A minimum is twice a week. Any less and you'll need to be a very influential person to get away with it.

One way of getting around having to post frequently yourself is to set up a group blog. But this can be difficult, unless the group shares a clear sense of purpose and similar attitudes. One successful example of this approach is Effect Measure, run by a group of public health professionals.

If the prospect of posting daily seems off-putting, remember that each post does not have to be a thousand words of carefully argued and finely crafted prose. Quite the reverse in fact — think of it as having a conversation with your readers.

Short observations on news events that use your expertise, for example to point out misconceptions, are great. Posts that link to new or interesting information elsewhere on the web are also very valuable.

You are using your special knowledge to filter the vast amount of content on the web for others. By aggregating material, you are editing the web for your readers. And remember, the links don't just need to be to articles. Video, pictures and graphics can be even more interesting. If I was blogging about penguins, I'd definitely be linking to this video. And taking your own photographs or video is even better — they are simple to add to blogs.

Technical aspects

I won't try to give a step-by-step account of how to blog here — there are plenty online. But if you can use a word processor and web browser, you already have 90 per cent of the skills you need. The other ten per cent are very simple, for example using basic HTML, or the buttons in your blog software, to make key phrases bold or to add web links.

There is a wide variety of blog software available, all with guides on how to use them. You can choose what suits your level of technical knowledge. The simplest host the blog for you, with the most popular being Blogger, Wordpress and Typepad.

The downside with these blog sites is that you have less control over the URL. If you want to host your own blog, check out Movable Type, for example.

The Guardian's blogging guru, Kevin Anderson, recommends guides to the pros and cons of different options available on these sites: Problogger, readwriteweb and pcworld.com.

Limited bandwidth and Internet access in some areas of the developing world may limit all forms of blogging.

Jonathan Gosier, a software developer living in Kampala, Uganda, describes blogging from a developing country as "a lesson in patience, endurance and ingenuity". On his blog on Apprifca he recommends ten applications that can ease the challenges of dealing with power cuts, unstable Internet connections and potential data loss.

Getting a readership

Once you have your blog up and running, you'll need to get people coming to visit. This can be hard at the start, but be patient. There are a number of things you can do, and the key is linking.

First, you need to include lots of links in all that you post. This helps with 'search engine optimisation', that is, it helps search engines understand the sorts of site your blog is like, and this means people searching for your topic will be more likely to find your blog.

Even more important is encouraging links from other sites to your blog. You can do this by leaving comments on other sites you like, which include links back to relevant posts on your blog. Note the word relevant — if your links are not relevant, they will annoy people, which is not a way to become popular.

You can also list the other blogs you like — this is called a blogroll. It's worth asking those bloggers if they would like to link to you — they will if they like your blog. Lastly, it's worth sending details of your blog to Technorati, which acts as a search engine specifically for blogs.

If you intend to blog about peer-reviewed research articles, you could register with Research Blogging, a website which highlights the posts of its registered users when they write about new journal papers.

Generating discussion

There's another important difference between blogging and conventional journalism and science communication. Writers of conventional media must not leave questions hanging — their stories need a beginning, middle and end. But blogging, being a conversation, means you can ask questions, as my food writer colleague Jay Rayner did recently on the topic of genetically modified foods.

A truly great science blog, also connected to the Guardian, is Bad Science, written by the medical doctor Ben Goldacre. His conversations with his readers often generate ideas for future posts.

Discussions with your readers is an essential hallmark of a good blog. A blog without discussion is like a radio talk show without callers — a lecture in fact. The simplest way to create a discussion is by asking for one — "what do you think of what I have written?" When someone does comment, make sure you reply to them on the blog. After all, you wouldn't ignore someone who spoke to you in person.

Not all comments will be interesting or constructive, and moderating the comments on your blog is a difficult balance. If you are oversensitive in deleting comments, readers will soon learn that you are not really interested in having a debate. On the other hand, if you let anything go, you will soon find your blog infested with trolls — people who post irrelevant and provocative comments to disrupt discussions — and this could bore or intimidate interesting people, driving them away.

Many trolls will back down if you reply personally to them. Their aggression fades when they realise there is a real person behind the screen. But I don't want to exaggerate this issue — getting any comments at all is harder than dealing with bad ones. And remember, the blog is your space. You are free to eject people you object to, just as in your own home.

Google adds automatic translation to Gmail

মঙ্গলবার, মে ২৬, ২০০৯

Google added automatic translation technology to Gmail on Tuesday, allowing users of its email service to translate messages in another language with a single mouse click.

The Mountain View, California-based Internet giant said it had integrated its Google Translate program into Gmail, allowing automatic translation of messages in several dozen languages.

"When you receive an email in a language other than your own, Gmail will help you translate it into a language you can understand," Google said in a post on the company blog.

"If all parties are using Gmail, you can have entire conversations in multiple languages with each participant reading the messages in whatever language is most comfortable for them," Google said.

Google has already made Google Translate available to provide automatic translations of entire Web pages or blogs.

Virtual Memory Low—What to Do?

রবিবার, মে ২৪, ২০০৯

Solution: I assume that you got a little balloon in the bottom right-hand corner announcing that your virtual memory is low and that Windows is adjusting it. If this happens just once, don't worry—as the message said, Windows found a problem and fixed it. But if it happens repeatedly, it could be that your settings don't allow Windows to make the necessary adjustment. First, make sure your drive isn't overly full. In Windows Explorer, right-click the drive icon and choose Properties. If the amount of free space is under about 10 percent, you'll need to free up some space. You can use the Disk Cleanup button right next to the free space indicator, or manually move some files to off-line storage, or uninstall unnecessary applications—whatever it takes to get more free space.

If low drive space isn't the problem, the virtual-memory settings may be wrong. Right-click My Computer and choose Properties. Click the Advanced tab. Click the Settings button in the Performance panel. Click the Advanced tab in the Performance dialog. Click the Change button in the Virtual memory panel. Whew! This setting is buried quite thoroughly! Look for the System managed size option, select it if it isn't already selected, and then click OK, OK, OK. That should end the warnings.

Cool Niche Social Networks

Forget Facebook. Here are 10 social networks for connecting all types of people, including knitters, car enthusiasts, and Harry Potter fans

Facebook, MySpace, and other general social networks are great for connecting with friends and sharing your interests. But they serve a general audience, and they don't always do a good job of filtering information to let you focus on a particular interest—whether it be a favorite book series, a collection of wines, or a particular sport. So instead of joining yet another Facebook group, why not try a niche social network?

There are lots of them out there for just about every interest, and they are constantly being added to. Companies have launched sites for gearheads, bookworms, and dog lovers. There are also services such as Ning, which allows individual users to create their own social networks—so far more than a million individual networks have been built with it. Special interest networks give fans and devotees a forum to indulge their passions and meet like-minded friends.

Here are 10 cool niche social networks you might be interested in joining.

BallHype

BallHype is a social network for sports lovers of all kinds. The site has a Digg-like interface for sports news and encourages interaction about news in each sport from the NBA to MLB to MMA (mixed martial arts).

Bottletalk

Bottletalk's social network for wine lovers lets users share their experiences and find wines based on others users' well-regarded wines. Along similar lines, Coastr lets beer enthusiasts find new brews and pubs to drink at.

Epernicus

This is the social network for connecting current and former research scientists. It allows scientists to share resources and help each other find ways to advance their work.

Fotolog

Fotolog is different from Flickr and other photo-sharing sites because you can post only one photo a day. It encourages community building, and its international following is huge.

Glee

Professionals who belong to the LGBT community will find a social network that caters to their interests at Glee (an acronym for Gay, Lesbian, and Everyone Else). In addition to offering opportunities to advance careers it offers traditional social features like music, blogs, groups, and chat

Motortopia

This social network allows car enthusiasts to talk shop, sell their cars to other members, and blog about their hobbies. If cars aren't your passion, the site also has tabs for bikes, boats, and planes.

MuggleSpace

With the latest Harry Potter film coming out on July 15, it might be time for a refresher with other fans. MuggleSpace is one of the top social networks for Potter-philes. It has chat, blogs, groups, and other features. In addition, MyLeaky—the social network for the fan site The Leaky Cauldron—offers interesting extras such as quizzes and House rankings.

MyDogSpace

If you love showing pictures of your dog to your friends, you'll enjoy showing them off to the dog-loving world at MyDogSpace, the social network for dog lovers. If your dog hates cats, don't tell him about the company's ironic sister site MyCatSpace.

Ravelry

Ravelry is a unique site for connecting knitters, crocheters, designers, spinners, and dyers. It helps users keep track of their yarn, tools, and pattern information, and lets them share ideas and inspiration.

Shelfari

Shelfari is one of the best sites for book lovers. When we reviewed the site, we liked it just a little more than the popular Goodreads because of the virtual bookshelf and slick interface that allow you to display your library to the world.

The Best Free Audio/Music Software of 2009

শনিবার, মে ২৩, ২০০৯

The best things in life often actually are free. Here, a list of the best things in life—free software, for entertainment and more.

Audio/Music


1. Audacity [HALL OF FAME]
audacity.sourceforge.net
Windows | Mac OS | Linux
On a par with any commercial audio editor, Audacity is the free sound editor of choice. The latest beta (1.3.6) even supports MPEG-4, Dolby Digital, and Windows Media.

2. Banshee
banshee-project.org
Linux
iTunes is riffed upon again, this time in a Linux-only option that supports audio and video, Android phones, and older iPods (but not iPhones or iPod touch... for now).

3. EphPod

If iTunes were entirely in the cloud, it would be pretty close to imeem (formerly Anywhere.FM). Upload your music collection and videos to stream from any device. Digital photos, too. You can share them with friends you make on the service.

6. iTunes [HALL OF FAME]
www.apple.com/itunes
Windows | Mac OS
Do we have to explain iTunes as the (so far) ultimate media player, coupled with online store and the primary way to get media—from music to video to games to podcasts, which plays most file formats (except, unsurprisingly, Windows Media formats)—and puts them on your iPod or iPhone? Probably not.

7. Mojo
www.deusty.com
Windows | Mac OS
When you and some friends install Mojo, you're ready for a unique sharing experience. Browsing and downloading MP3s from each other's iTunes music libraries is suddenly a very easy proposition. If it's a DRM file from the iTunes store, Mojo highlights them in red so you won't be bothered trying.

8. Songbird
www.getsongbird.com

Still a primo MP3 player, Winamp is both customizable (it heralded the age of "skins" on software) and comes in multiple versions, including one that works with CDs.

Battery Materials Market to Swell, No Thanks to Lead

রবিবার, মে ১০, ২০০৯

Lead metal is about to go the way of so many pop stars: out of the limelight. It’s had a good long run as the material of choice for batteries, but new materials that allow for faster charging, lighter weight, and higher energy density are poised to be the moneymakers of the world battery materials market in coming years. According to a report released this week from research firm Freedonia Group, lithium-ion and nickel metal hydride batteries — increasingly being used for consumer electronics and cars — will drive three years of growth for the battery materials market amid a gloomy outlook for “more mature and outdated” battery types such as lead acid and zinc carbon. Freedonia’s analysts anticipate world demand for materials used to make batteries will rise 3.9 percent per year to $22.8 billion in 2012.

“A major shift is under way in the market for lithium chemicals,” the firm writes, and companies in India, Indonesia, South Korea and especially China stand to see the most growth as a result. The outlook through 2012 isn’t as rosy for North America and Western Europe, Freedonia says, since their battery markets are more mature and dependent on lead, which is expected to have slumping prices in the next few years.

North America, however, could still see some bright spots — largely thanks to entrepreneurial activity. Freedonia expects the region’s nascent advanced rechargeable cell industry — an area increasingly populated with startups, including Seeo, Boston-Power, Z-Power and ActaCell — and production of batteries for hybrid and electric vehicles to present opportunities for growth.

Despite Freedonia’s dim outlook for lead, some companies think there’s still room for innovation with the material. When we looked at whether lead-acid batteries can compete in an increasingly lithium-ion world earlier this year, we spoke with Thomas Granville, the CEO of Axion Power, a Quercus Trust-backed startup working to blend ultracapacitor tech with old-fashioned lead-acid batteries for a lead 2.0 device that could have applications in after-market vehicle conversions and grid buffering.

Tricks to use Pop up Blockers in Windows

Pop-up window messages basically used for online advertising to increase the web traffic with minimum cost, but these pop-up messages can be used to damage a computer or also for hacking purpose. In routine when you are browsing the internet and suddenly a new window pop-up dialog box display with different messages for example" speed-up your internet ","free upload your files or images". All pop-up messages are not dangerous for you but some unwanted program and website that might be disturb your computer performance.
There are many free pop-up blocker software's available in market but always download it from well-known sites. Simply Download Google toolbar and install it to use its feature "Block annoying pop-up" to block the pop-up messages, You can say this is simple and best way to block unwanted program.

If you are working with Internet Explorer and want to block the pop-ups windows and unwanted messages. Open the Internet Explorer and click on Tools menu and go to Pop-up Blocker option, here you can Turn Off Pop-up Blocker to block pop-up from all websites. But you have option to allow some websites for pop-up. For this purpose open the Pop-up Blocker Setting. Here you can add some specific websites name to allow for pop-up and click Add. If you feel any problem to block any pop-up message due to some problem, simply click on the X at the right top of the pop-up windows.

How to increase Ram for speed up PC

শুক্রবার, মে ০১, ২০০৯

Problem 1: Not enough RAM


RAM stands for Random Access Memory and is used as a temporary storage memory by your computer. This memory is in use when tasks are being executed by different programs. Hence, you should have enough RAM memory to process all the tasks at hand; if you don this might cause the major slow down of your computer while it is booting up or processing tasks.

How to know if your computer has enough RAM


The programs that are installed on your computer usually have RAM requirements that are asked. If your computer has been running at a normal speed before the installation of such programs and has crucially slowed down with time, you might need to add more RAM on your computer system.
Also, if your computer is slowing down every time you are processing large files, or it freezes while executing several programs at once, these might be some common signs that you need to add extra RAM.

Problem 2: Temporary files have built up on your hard disk


Some tasks might require you to leave the system working for several days and this might cause temporary files to build up on your hard disk. This might be a reason why your computer is slowing down and is taking some time to boot up as these type of files tend to be memory consuming.Cleansing your temporary files including your Internet history including cookies gives you a larger amount of hard disk space to work with.

How to delete Temporary Files


1. Open My Computer and select your local drive (it is usually labeled as :\C)
2. Select theWindows folder and locate the folder labeled Temp
3. Use your mouse to right-click on the folder (not the contents) and in the View options, choose Detail
4. Select all the files that are older than the current date and press the delete key.
5. When done, go to the Recycle Bin on your desktop and choose Empty Recycle Bin
You can also choose to delete the Temporary Internet Files that have accumulated on your system
1. Go to your Start button and open Control Panel
2. Select Internet Options and in the section labeled Temporary Internet Files press Delete Cookies and Delete Files options.
3. You can also delete your history by clicking the option “Clear History
4. When done, press Apply and OK
When you finish removing the Temporary Files, reboot your computer.

Problem 3: Your computer has been infected


If your computer has been infected by a virus, a malware, a worm or a Trojan, it might have cause the slow down of your computer system and even freeze several tasks at hand. Hence, you should run a virus scan and remove all the infected files found on your system.

Problem 4: Not enough space on the hard disk


Adding very bulky programs will automatically slow down your computer system. Hence, I will suggest users with a hard disk capacity of 2GB to leave at least 250MB free and those who have a higher hard disk storage capacity to leave at least 20% of the total capacity free. This will hence allow your computer to have enough room both for temporary files and file swapping.

Defragmenting your hard disk


You can also choose to defragment your hard disk to gather some dispersed spaces that can be used by the computer again.
1. Go to your Start menu and list all programs
2. In the Accessories option, select System Tools
3. Choose Disk Defragmenter from the list
4. To start the process, click the Defragment button.

Problem 5: Your Direct Memory Access (DMA) is disabled


The Direct Memory Access will allow data transmission between your hard drive and CD drive without requiring the microprocessor intervention. Those using Windows XP will not have this option set by default.
1. Click on the Start button and open Control Panel
2. Click and open the System icon

Update Your Operating System


Having the latest updates of Windows will not increase system performance. However patching up any security loop holes or performance related glitches may be beneficial. So in the long run, your system will be better off with the latest OS updates.

How to increase Ram for speed up PC

Problem 1: Not enough RAM


RAM stands for Random Access Memory and is used as a temporary storage memory by your computer. This memory is in use when tasks are being executed by different programs. Hence, you should have enough RAM memory to process all the tasks at hand; if you don this might cause the major slow down of your computer while it is booting up or processing tasks.

How to know if your computer has enough RAM


The programs that are installed on your computer usually have RAM requirements that are asked. If your computer has been running at a normal speed before the installation of such programs and has crucially slowed down with time, you might need to add more RAM on your computer system.
Also, if your computer is slowing down every time you are processing large files, or it freezes while executing several programs at once, these might be some common signs that you need to add extra RAM.

Problem 2: Temporary files have built up on your hard disk


Some tasks might require you to leave the system working for several days and this might cause temporary files to build up on your hard disk. This might be a reason why your computer is slowing down and is taking some time to boot up as these type of files tend to be memory consuming.Cleansing your temporary files including your Internet history including cookies gives you a larger amount of hard disk space to work with.

How to delete Temporary Files


1. Open My Computer and select your local drive (it is usually labeled as :\C)
2. Select theWindows folder and locate the folder labeled Temp
3. Use your mouse to right-click on the folder (not the contents) and in the View options, choose Detail
4. Select all the files that are older than the current date and press the delete key.
5. When done, go to the Recycle Bin on your desktop and choose Empty Recycle Bin
You can also choose to delete the Temporary Internet Files that have accumulated on your system
1. Go to your Start button and open Control Panel
2. Select Internet Options and in the section labeled Temporary Internet Files press Delete Cookies and Delete Files options.
3. You can also delete your history by clicking the option “Clear History
4. When done, press Apply and OK
When you finish removing the Temporary Files, reboot your computer.

Problem 3: Your computer has been infected


If your computer has been infected by a virus, a malware, a worm or a Trojan, it might have cause the slow down of your computer system and even freeze several tasks at hand. Hence, you should run a virus scan and remove all the infected files found on your system.

Problem 4: Not enough space on the hard disk


Adding very bulky programs will automatically slow down your computer system. Hence, I will suggest users with a hard disk capacity of 2GB to leave at least 250MB free and those who have a higher hard disk storage capacity to leave at least 20% of the total capacity free. This will hence allow your computer to have enough room both for temporary files and file swapping.

Defragmenting your hard disk


You can also choose to defragment your hard disk to gather some dispersed spaces that can be used by the computer again.
1. Go to your Start menu and list all programs
2. In the Accessories option, select System Tools
3. Choose Disk Defragmenter from the list
4. To start the process, click the “Defragment button.

Problem 5: Your Direct Memory Access (DMA) is disabled


The Direct Memory Access will allow data transmission between your hard drive and CD drive without requiring the microprocessor intervention. Those using Windows XP will not have this option set by default.
1. Click on the Start button and open Control Panel
2. Click and open the System icon
3. Select the Hardware tab and choose Device Manager option.
4. List the ATA/ATAPI options by clicking the + icon next to it.
5. Select the Primary IDE Channel option
6. In the Primary IDE Properties window select the Advanced Settings tab
7. Check whether theTransfer Mode for Device enables DMA.
8. Also, check whether the Transfer Mode for “Device enables DMA.
9. Click OK to confirm the changes
10. Hence, click Secondary IDE Channel
11. In the Secondary IDE Propertie, select the Advanced Settings tab
12. Check whether the Transfer Mode for Device enables DMA.
