Dalam melakukan survey, tim diharuskan cukup banyak mendapat data. Kondisi geografi, berupa jenis tanah, sungai, jembatan dll, data koordinat lokasi dan beberapa info penting lainnya.
Khusus utk data koordinat longitude/latitude, data yg diperoleh seringkali dalam bentuk derajat, menit, detik. Padahal bila ingin memeriksanya dalam google map lebih mudah menggunakan desimal. Oleh karena itu harus ada konversi dari format derajat, menit, detik ke format desimal. Berikut ini tahap konversi sederhana :
-Kunjungi website http://transition.fcc.gov/mb/audio/bickel/DDDMMSS-decimal.html
-masukan derajat, menit, detik pada kolom yg tetrsedia.
-bila pada kolom detik, terdapat satuan koma gunakan titik (.)
-klik "Convert to Decimal"
-akan muncul hasilnya di kolom terbawah.

Kali ini ceritanya rada inggris ya....
Biar penulisnya cepet bisa bhs bule...
Long gone are the days of shopping exclusively in stores and spending only money that's in your wallet. Sure, we've all got Pay Pal accounts these days, and purchasing goods and digital content from pretty much anywhere has never been easier. But the sheer number of mobile devices in consumers' hands magnifies the effect, and Juniper Research has recently released a report on just how big the Mobile Payments space has become.
Mobile Money Goes Mainstream is a whitepaper extract from Mobile Payment Strategies- Opportunities & Markets 2011 – 2015, from Juniper Research. When I was first approached about taking a look at the report, I was a bit underwhelmed in that I thought I was in tune with all things mobile, and that people shopping through their iPhones hardly rises to the level of news. As I dug in on the piece, I realized that I am pretty much a bumpkin on the topic.
Big numbers are meant to impress, so let's get right to the one that matters. Juniper estimates that by 2015, the global mobile payments market will be worth almost $700 million dollars. Given that much of that occurs in increments of somewhere under a dollar to around twenty dollars, it is pretty thought provoking from the perspective of volume of transactions. But what is really fascinating to the uninitiated is the clinical breakdown of payment schemes, and exactly what methods are being used to spend these dollars from mobile devices in various parts of the world, and how money spent is spread across both digital and physical goods and funds transfers. This is where the report packs its punch.
It's not oversimplifying the point to say that phones are supplanting cash in some countries, where "Near Field Communications" amount to the wave of a device that makes money change accounts. Then there are in-app billing mechanisms, my phone talking to yours directly for Person2Person payments, and a handful of other classifications of mobile payment schemes. There are definitely preferred ways of mobile shopping as you travel the world, implications for lower-tech countries, and a lot of food for thought for those looking to make revenue off of the opportunities afforded by new ways of getting customers to part with their money. Those with a stake in the mobile payment realm are likely going to want to give this one a read.
As I ponder the implications after digesting the whitepaper summary, I feel the familiar left brain-right brain conflict kick in- the one that frequently pops up when analyzing current IT trends. In this case, I truly appreciate the innovative, technically progressive ways in which those wanting to can shop for content or material items without needing to fork over dollar bills, pounds, pesos, or yuan. At the same time, when it comes to spending money, ease isn't always a good thing, especially for those who don't manage their finances well to begin with. I fully realize that the genie is out of the bottle on mobile payment. Now hopefully somebody will come up with a "uh, do you really NEED that thing you're thinking about buying just because it's so easy to buy that that thing" app.

Nokia kembali membuat gebrakan. Kali ini bersinergi dengan Microsoft untuk meluncurkan aplikasi di bidang mobile productivity, yaitu Microsoft Communicator Mobile pertama di ponsel Nokia." Microsoft Communicator Mobile adalah aplikasi client semacam pesan instan besutan Microsoft, yang lebih menyasar lingkungan korporat," kata  Kirt Debique, General Manager Microsoft, dalam siaran persnya.
Berbeda dengan Windows Live Messenger (dulu MSN Messenger) yang menargetkan pada pengguna perorangan, Communicator Mobile bekerja pada platform Microsoft Office Communication Server. "Aliansi kami dengan Nokia bertujuan untuk menyediakan pengalaman produktivitas Office kepada jutaan orang yang menggunakan ponsel pintar Nokia di seluruh dunia," tambah Debique.
Communicator Mobile merupakan sistem komunikasi perusahaan dan memungkinkan adanya mobile collaboration. Dengan aplikasi ini seseorang bisa melihat status kehadiran (availability) rekan kerja, mengkliknya untuk saling berkomunikasi, baik dari IM ke email, atau dari SMS ke panggilan telepon.
Nama dan status teman akan terlihat langsung di aplikasi kontak ponsel, dan aplikasi ini juga memudahkan pengguna untuk mengupdate status baru mereka saat hendak bergabung dengan sesi pesan instan, atau menelepon langsung dari kartu kontak.
"Aplikasi ini benar-benar menyediakan cara yang efisien untuk bekerja bersama dengan mitra, karena Anda bisa melihat apakah orang itu sedang sibuk atau sedang available, dan ini cara yang baik untuk memulai pembicaraan dengan mereka," ujar Ukko Lappalainen, Vice President Nokia.
Selain itu, Lappalainen mengatakan bahwa aplikasi ini memenuhi kebutuhan perusahaan terhadap kelancaran komunikasi karyawan, karena efisiensi biaya, implementasi, keamanan, mudah, dan andal. Peluncuran ini merupakan hasil kerja sama pertama dari kedua perusahaan. Sejak produk ini diumumkan sejak Agustus lalu, Microsoft dan Nokia telah berkolaborasi pada desain dan pengembangan solusi baru, sekaligus kerja sama di bidang pemasaran.Menurut Scott Petty, Director Vodafone Group Business Services, Communicator Mobile cocok bagi konsumen korporat yang sebelumnya telah menggunakan Communicator untuk komputer desktop.

Terhitung hari ini Communicator Mobile untuk Nokia sudah bisa diakses melalui toko aplikasi virtual Ovi Store. Untuk saat ini aplikasi tersedia untuk Nokia E72 dan Nokia E52. Rencananya, Qwerty terbaru andalan Nokia yang akan dirilis pada kuartal tiga, Nokia E5 juga bakal dibekali Communicator Mobile secara pre-installed.

One of the best and cheapest ways to talk to people today isn't on a cell phone. A trend in many businesses is to utilize their existing Internet connections and use VoIP services like Cisco and Vonage to make their business calls. Doing so will save them big bucks if they can eliminate there need for a leased line for phone communications. Cell phones are limited in the areas they cover, and they typically cost more to operate than Internet VoIP aplications. To use your computer to make phone calls you will need VoIP software and a computer headset to allow you to talk over the Internet for free, if you buy a service such as Vonage you can make local and long distance calls for free. So, if you decide to go this route here are a few pointers when purchasing you new computer headset. Don't Buy the Cheapest When purchasing a computer headset it is not wise to go for the cheap, ten-dollar version sold by the generic technology companies. These may function well enough to suit you, but after a while you will be disappointed with there quality. Most of the cheaper models are generally fairly uncomfortable and will only give you lackluster performance. Paying a little more for a good quality computer headset will dramatically increase the audio quality of both inbound and outbound voice calls. Headsets have been popular for use with computer games for a few years now, the recent trend in Internet gaming as helped boost the market. Bluetooth computer headsets have also been growing in popularity over the past few years in the business world to help increase mobility and productivity. Computer Headsets for Business Use Computer headsets are providing the necessary interface to the computer to allow business users to make all of their contact calls over the computer and utilizing the Internet to make the call for free. Headsets can also be used in the business world in places like call centers to cut down on the background noise of having so many employees on the phone at the same time in a small area. This allows for more private communication as well. Gone are the days of shelling out huge amounts of money every month for cell phone plans for each employee. By using the computer to make phone calls the only items you need to by is the VoIP software and a reliable headset for the user to wear. This setup will save you money in the long run compared today's expense cell wireless carrier plans. Computer Gaming Headsets If you are into computer games for the Xbox, Playstation and Wii, the latest craze is to play against one another over the Internet. This allows users from all over the world to play against each other in a virtual space, the Internet. However, if you are going to stay competitive in this world of high tech gamers, you will definitely need at computer headset to connect to your Xbox or Playstation. These headsets are typically wireless, using Bluetooth technology. Of course if you are the traditional computer gamer, your computer headset will be plugged into your ultimate gaming PC and you'll be playing something like Counter-Strike or World of Warcraft. If this is the case, you may want to go with a USB interface for your computer headset. This style will be directly wired to your PC and will not require you to replace the batteries. This style tends to be more comfortable and offers a much high audio quality than some of the cheaper wireless models available. It is important to remember there are many different styles of headsets available and each with fit a little differently. If you are using the computer headset strictly for audio then you will need just the ear pieces, basically traditional headphones. But if you plan on using the headset to communicate for gaming of phone service you will need a headset with a mic in order to have two-way communication. Just remember, cheaper is not always better especially in computer headsets. There is a big difference in quality between the low to mid grade as compared to the more pricier higher quality headsets. My advice is to get a mid level priced headset to start out and then if you find yourself using it more and more, you can later upgrade to a higher quality model. (source :ezine3000)

Ask a dozen Internet experts what the term Web 2.0 means, and you'll get a dozen different answers. Some say that Web 2.0 is a set of philosophies and practices that provide Web users with a deep and rich experience. Others say it's a new collection of applications and technologies that make it easier for people to find information and connect with one another online. A few journalists maintain that the term doesn't mean anything at all -- it's just a marketing ploy used to hype social networking sites.


The O'Reilly Media Web site is a prime example of
Web 2.0 at work.



Before we get into the debate about what Web 2.0 actually means, let's look at where the phrase originated. In 2004, publishing firm O'Reilly Media and tradeshow production company MediaLive International had a brainstorming session. The two companies planned a conference that addressed the state of the Web, its future and the emerging techniques that would help ensure its success on the Internet. Tim O'Reilly, founder and CEO of O'Reilly Media, wanted to make the point that despite the dot-com crash of 2000, the Web was sure to become an enormous revenue generator.

During this brainstorming session, O'Reilly Media publisher Dale Dougherty coined the phrase Web 2.0 to describe the new Web environment that emerged after the crash. While dozens of Internet companies had declared bankruptcy, a few hardy sites managed to survive. New Web sites were appearing every day, and many of them used drastically different business models than the commercial sites that existed before the crash.

Still, no one had a clear definition of what Web 2.0 actually meant. If there really was a Web 2.0, did that mean there was also a Web 1.0? The use of "2.0" implied an improvement, or a new generation of Web sites, but there was no consensus on what made Web 2.0 different from Web 1.0.

In September 2005, Tim O'Reilly posted a blog entry that defined Web 2.0. The explanation spanned five pages of text and graphics illustrating O'Reilly's take on what the term meant.

O'Reilly's philosophy of Web 2.0 included these ideas:

Using the Web as an applications platform
Democratizing the Web
Employing new methods to distribute information
In this article, we'll explore each of these points. We'll also look at the debate about whether or not Web 2.0 actually has a practical meaning.

Video Gallery: Online Social Networking
Social networking sites reflect the Web 2.0 philosophy. In this video from PodTech, learn about Renkoo, a site that combines the concepts of social networking with event planning.

Have you ever been doorbell ditching before? The point of the prank is simple: Sneak up to someone's front door, knock loudly or ring the doorbell, and, instead of greeting whoever answers the door, run away and hide somewhere nearby. The joy of doorbell ditching is, of course, reveling in the homeowner's confusion and rolling with laughter under the security of his nicely trimmed bushes. Although the game might get you in a bit of trouble if you happen to incite the ire of a cranky neighbor, it's mostly a harmless joke on par with a prank phone call.

For more technically inclined pranksters with access to Bluetooth technology, however, there's the digital version of doorbell ditching and prank phone calls: Bluejacking. A kind of practical joke played out between Bluetooth-enabled devices, bluejacking takes advantage of a loophole in the technology's messaging options that allows a user to send unsolicited messages to other nearby Bluetooth owners.
The only difference between doorbell ditching and bluejacking is that bluejacking usually isn't done on your neighbor's lawn. Instead, a bluejacker will most likely camp out in crowded areas like shopping malls, airports and subway systems to find victims -- places with a potentially high percentage of people with Bluetooth-enabled devices. The trend has even fostered fan Web sites, where Bluetooth users inform newcomers how to bluejack, trade tips and post amusing bluejacking stories that include every keystroke and puzzled look.
So how is bluejacking done? What is it about Bluetooth technology that makes it possible to bluejack? Does it have anything to do with hijacking information from another Bluetooth device, and can it cause any harm? Are there any privacy concerns? To learn how bluejackers engage each other, confuse one another or simply annoy innocent bystanders, read the next page.

Keeping people interested in your blog, whether it is a business or personal blog, is key to attracting a lot of regular visitors. Many blogs have died because people have just lost interest, take the Computer and link to internet. The main reason for the lack of interest is simply a lack of posts by the blogger. Regular, frequent posting, which will boost your blog’s ranking in search engines, is essential to the survival of any blog.

You might be asking yourself, what is frequent posting? How many blog entries should I make on a given week? How do I make frequent consistently good posts? What are the reasons for me to post frequently? In this newsletter, we will go over all of the above.

What is frequent posting?

Frequent blog posting is posting enough to keep your readers interested. Obviously, people will not want to come back to a blog that hasn’t been updated in months. They want to see consistent posting so that they know coming back to check the blog next week to see if there are more posts won’t be a waste of time.

How many blog entries should I make each week?

This is one of the tougher questions to answer. It really depends on the purpose of your blog. If it’s a personal blog, a weekly or twice weekly update is an excellent idea. A political/sports/music/religion blog should have 3-4 posts per week. Business blogs should have at least 2 posts, but preferably 4 each week.

The thing to remember is that quality counts. Posting frequently just for the sake of posting frequently tends to result in subpar posts which people won’t care about. It is important to find a balance—frequent, quality posts that won’t result in burnout on your part. Why create 4 poor quality posts each week when you could post 2 quality posts per week?

How do I create quality postings on a consistent basis?

It’s all about following a consistent pattern of writing. Maybe you’re not a natural writer and this is difficult. That’s why we’ll give you an outline to help you.

1. Pick a topic that is interesting to you and to your readers. Maybe if your blog is a personal blog, you could write about the latest happenings in Hollywood.

2. Carefully think about what you’ll write about the topic. It makes it easy to make quality blog postings if you know exactly what you’ll write. Plot out everything about the post before even beginning to write it.

3. Before writing your content, pick out some keywords that are relevant to your blog. If you naturally use keywords throughout your post, you will please search engine spiders which will get your blog ranked higher on search engines. Your visitors won’t mind the use of keywords if they are used in a tasteful way.

4. Begin writing your post. Don’t limit yourself to a particular amount of words. Just do what’s natural. And if any blog post is hard for you, just take a timeout and relax. You should be able to finish the post a bit later on, after you’ve had some time to think things through, you should be able to finish the post with no problems.

Why is frequent posting important?

Blogs are meant to be outlets for individuals or businesses. They are used to get an opinion out on something and to engage readers. Readers need to have something that makes them want to keep coming back to a blog. That something is usually quality, frequent posts.

Gaining and maintaining visitors isn’t the only reason to post often in your blog. Catching the eye of a search engine—and achieving a high ranking—is another valid reason for posting frequently. Most likely, each posting in your blog features some keywords or keyword phrases scattered throughout it. Logic says that the more natural keywords you have on a blog, the better. Thus, the more posts you make on your blog, the more keywords you have on there. And the more keywords you have, the more likely a search engine bot is to crawl your site. The more your site is crawled by bots, the more likely it is that you will have a high ranking on a search engine.

Frequent blog posting can be easy as long as the person who is posting takes the time to plot out what they’ll write about. So take a few minutes to think about your post and then just do it!

Blogs are now an extremely popular and important part of the internet. Millions of people blog every day. As blogs have evolved over the years, so has the commenting system. Now anyone can make comments on a particular blog posting. As blog commenting has grown more popular, so has spam commenting. In this newsletter, we’ll go over why comments are a great form of feedback for your blog, how they help the credibility of your content, what spam comments are and how to prevent them from happening.

Comments – A great form of feedback

When blogs first came around, they were simply online journals. No one could post comments on a blog posting. That all changed in 1998 with OpenDiary, a site which allowed people to comment on blog postings. Now every blog, whether it is remotely or self-hosted, includes this option to comment.

Commenting is great because it allows real people to tell you what they think about your form. It gives you feedback on what you are doing right and what you may need to improve. Comments can be encouraging to you and motivate you to post more quality blog messages. Or they can be constructive criticism to make you work harder to get better at writing content.

Whatever the style of comment is, it is still very useful to your blog. High numbers of comments have the ability to make a blog look credible because they show that the blog is being read by a lot of people. That’s something that every blog owner wants, and comments help to let them know just how many people enjoy their content.

Bad comments

Unfortunately, spammers have now started to use comments as a way to spam. How do you know what a spam comment is? Well, a spam comment is a comment that only advertises another site or product. If the comment seems bland/generic with a cheap link thrown in, then it’s definitely a spam comment.

Here is an example of a typical spam comment:

“Hey, this site is really cool. Check out my really cool site at spamsite.com.”

Of course not all spam comments will be this blatant, but you get the point.

Fortunately for bloggers, as spam comments have grown, so has the ways to prevent it. Here are a couple ways that you can prevent spam comments from even being posted on your blog.

#1: Close off commenting on older blog posts

There are options for you to stop comments from being posted on any particular blog post. Lots of times, spammers will post comments in weeks or months old posts. So take away this opportunity from them to keep it from happening. Most blog hosters now offer this as a standard option in the tool panel. If one of your posts has been up for a couple weeks, close it up.

#2: Take advantage of software offered to prevent comment spam

If you host your own blog using WordPress, you can use an option in that software to prevent spam. Even if you aren’t using WordPress, you can still use other Spam comment blocking software like Spam Karma, Akismet, and Bad Behavior. While these aren’t 100% effective, they have proven to be quite effective in preventing spam from happening.

#3: Take a look at your settings and see what can be tweaked to toughen your protection

Lots of blogs now have settings to help prevent spam. If you already have a spam blocker on in your blog and are still experiencing spam, take a closer look at the settings to see if there’s anything that can be tweaked to make your protection stronger. However, if you do this, you should closely monitor your posts to make sure legit comments aren’t being blocked out. If they are, you might have to lighten up a bit.

#4: Regularly read your blog comments

Be sure to keep an eye on your comments. Even the best software or setting can’t prevent everything, so you will have to occasionally manually remove comments on your own.

By applying the above principles, you can ensure that your blog is full of only good, quality comments, which will help your credibility tremendously.

Comments are a great form of communication between yourself and your readers. They help the credibility of your blog!

There are lots of different ways that electronic devices can connect to one another. For example:
• Component cables
• Electrical wires
• Ethernet cables
• WiFi
• Infrared signals
When you use computers, entertainment systems or telephones, the various pieces and parts of the systems make up a community of electronic devices. These devices communicate with each other using a variety of wires, cables, radio signals and infrared light beams, and an even greater variety of connectors, plugs and protocols.
The art of connecting things is becoming more and more complex every day. In this article, we will look at a method of connecting devices, called Bluetooth, that can streamline the process. A Bluetooth connection is wireless and automatic technology, and it has a number of interesting features that can simplify our daily lives.


The Problem
When any two devices need to talk to each other, they have to agree on a number of points before the conversation can begin. The first point of agreement is physical: Will they talk over wires, or through some form of wireless signals? If they use wires, how many are required -- one, two, eight, 25? Once the physical attributes are decided, several more questions arise:
• How much data will be sent at a time? For instance, serial ports send data 1 bit at a time, while parallel ports send several bits at once.
• How will they speak to each other? All of the parties in an electronic discussion need to know what the bits mean and whether the message they receive is the same message that was sent. This means developing a set of commands and responses known as a protocol. Bluetooth offers a solution to the problem.

Why is it called Bluetooth?
Harald Bluetooth was king of Denmark in the late 900s. He managed to unite Denmark and part of Norway into a single kingdom then introduced Christianity into Denmark. He left a large monument, the Jelling rune stone, in memory of his parents. He was killed in 986 during a battle with his son, Svend Forkbeard. Choosing this name for the standard indicates how important companies from the Nordic region (nations including Denmark, Sweden, Norway and Finland) are to the communications industry, even if it says little about the way the technology works.

In using Computers, it appears that the venerable wheeled mouse is in danger of extinction. The now-preferred device for pointing and clicking is the optical mouse. Developed by Agilent Technologies and introduced to the world in late 1999, the optical mouse actually uses a tiny camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS) sensor.

The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP, operating at 18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, making the cursor appear to move very smoothly.
Optical mice have several benefits over wheeled mice:
• No moving parts means less wear and a lower chance of failure.
• There's no way for dirt to get inside the mouse and interfere with the tracking sensors.
• Increased tracking resolution means smoother response.
• They don't require a special surface, such as a mouse pad.
Although Technology LED-based optical mice are fairly recent, another type of optical mouse has been around for over a decade. The original optical-mouse technology bounced a focused beam of light off a highly-reflective mouse pad onto a sensor. The mouse pad had a grid of dark lines. Each time the mouse was moved, the beam of light was interrupted by the grid. Whenever the light was interrupted, the sensor sent a signal to the computer and the cursor moved a corresponding amount. This kind of optical mouse was difficult to use, requiring that you hold it at precisely the right angle to ensure that the light beam and sensor aligned. Also, damage to or loss of the mouse pad rendered the mouse useless until a replacement pad was purchased. Today's LED-based optical mice are far more user-friendly and reliable.

One nuisance that has been around for as long as the internet, is the existence of extraneous files that accompany websites.

When you upload your website, you need to make sure that along with it you upload every image file you want to use, every Cascading Style Sheet (CSS) that determines font styles, every video or audio clip you want to include, and lots of other files as well.

If you don't have a well organized filing system, it is easy to misplace or lose files amonst the clutter. And even with a good system, you may leave old files on your site that are no longer used and are just taking up space.

File Clean Up

The makers of XSitePro 2.0 understand the problems associated with building and maintaining a website, so they have built tools into their software to manage a lot of those problems with a minimal amount of effort.

The program's suite of Website Cleanup tools are able to tell you if there are any files that are no longer needed, redundant, or out-dated. And, because this powerful package can handle the publishing of your website to the server, it ensures that everything is uploaded in an organized fashion.

Mapping Your Site

Along with creating all of the files and content for your website, you also have to remember what everything is for and where it is. When a site comprises just a few pages, that may be simple, but as your site grows in content and size, it becomes more complex.

Enter the automatically created Full Sitemap function. It helps you keep track of each facet of your site, and is an excellent way to help your website's visitors find precisely what they are seeking. And, as an added bonus, sitemaps help ensure that your entire website gets indexed by search engines.

Computers are essential in every aspect of our lives. We need them at work, school, business, recreation and a lot more. Because of this importance, you will virtually find every household equipped with PCs or laptops. Since this device is important in our day to day activities, keeping the computer in excellent shape is a must. But since this is regularly used, computers would start to malfunction and result to slow PC XP. There are actually several reasons why computers start to slow down its performance and how to resolve them.

The very first cause of a slow PC XP is the registry. This is basically responsible for holding the entire computer system, hardware and the software preferences. Registry will be damaged once it is infected with dirt hence cleaning is a must. This will not only free up the space but registry cleaning would also solve some of your computer system's errors that can give you computer problems in the near future. To clean the registry, you can find different cleaning registries in the market today. You just have to guarantee that what you will choose is updated and reliable. Cleaning your computer's registry will do miracles on your computer's performance and speed.

The spyware and viruses could also be one of the reasons of a slow PC XP. Once surfing the web, you will eventually encounter viruses and spywares that would infect your PC. Staying out of the internet is not an option instead, you have to make sure that your computer is installed with a virus or spyware scanner in order to prevent any virus infection. These spyware/virus scanner will clean and delete all these harmful viruses that could cause havoc to your computer's entire performance. Do not settle for any substandard anti-spyware as this won't help you in increasing your computer's speed. What you need is a good quality antivirus that can do great wonders in your PC. This computer trouble must be immediately solved as this could not only slow PC XP but also put your computer to a complete halt.

And lastly, your computer's slow performance could be the cause of too little memory. As too much computer breakthroughs happen, more and more computer programs need more RAM in order for the computer to run smoothly. A computer equipped with sufficient RAM is a must in order to let your computer perform its topnotch shape. Adequate RAM is also important especially if you are running multiple programs at a time. A computer with a Windows XP operating system can usually run with a 512 MB of memory. But if your computer is equipped with many programs and applications, it needs twice as much as RAM in order to perform faster.

There are still many other factors that could slow PC XP however the above mentioned factors are the most common. These three, corrupt registry, viruses and inadequate memory are the factors that you should be careful about in order not lose your computer's speed.

Virus authors adapted to the changing computing environment by creating the e-mail virus. For example, the Melissa virus in March 1999 was spectacular. Melissa spread in Microsoft Word documents sent via e-mail, and it worked like this:

Someone created the virus as a Word document and uploaded it to an Internet newsgroup. Anyone who downloaded the document and opened it would trigger the virus. The virus would then send the document (and therefore itself) in an e-mail message to the first 50 people in the person's address book. The e-mail message contained a friendly note that included the person's name, so the recipient would open the document, thinking it was harmless. The virus would then create 50 new messages from the recipient's machine. At that rate, the Melissa virus quickly became the fastest-spreading virus anyone had seen at the time. As mentioned earlier, it forced a number of large companies to shut down their e-mail systems.

The ILOVEYOU virus, which appeared on May 4, 2000, was even simpler. It contained a piece of code as an attachment. People who double-clicked on the attachment launched the code. It then sent copies of itself to everyone in the victim's address book and started corrupting files on the victim's machine. This is as simple as a virus can get. It is really more of a Trojan horse distributed by e-mail than it is a virus.

The Melissa virus took advantage of the programming language built into Microsoft Word called VBA, or Visual Basic for Applications. It is a complete programming language and it can be programmed to do things like modify files and send e-mail messages. It also has a useful but dangerous auto-execute feature. A programmer can insert a program into a document that runs instantly whenever the document is opened. This is how the Melissa virus was programmed. Anyone who opened a document infected with Melissa would immediately activate the virus. It would send the 50 e-mails, and then infect a central file called NORMAL.DOT so that any file saved later would also contain the virus. It created a huge mess.

Computer Software Microsoft applications have a feature called Macro Virus Protection built into them to prevent this sort of virus. With Macro Virus Protection turned on (the default option is ON), the auto-execute feature is disabled. So when a document tries to auto-execute viral code, a dialog pops up warning the user. Unfortunately, many people don't know what macros or macro viruses are, and when they see the dialog they ignore it, so the virus runs anyway. Many other people turn off the protection mechanism. So the Melissa virus spread despite the safeguards in place to prevent it.

In the case of the ILOVEYOU virus, the whole thing was human-powered. If a person double-clicked on the program that came as an attachment, then the program ran and did its thing. What fueled this virus was the human willingness to double-click on the executable.
