Computer Viruses! What really is it?

---

     One might think of a computer virus as a tiny computer program designed to perform mischief. Most computer users have heard about computer viruses. A computer virus is the result of a destructive program that someone has written and placed inside a computer program, which unsuspecting people then place in their computer system.Some viruses can erase all the information from the place where it’s stored on the computer’s hard disk. But each virus is different. Some display strange messages on your computer screen; others make small changes in your computer programs.Where do these viruses come from? They certainly don’t float around in the air like some human viruses. Instead, like any other computer program, a human must create them.    Why do people create them? It’s hard to say. Some people create these programs out of meanness to get even. While others create them just as a challenge. Why do you thing people create these very destructive programs? How does your computer get a virus? Almost exactly the way humans do. The computer gets exposed to one. Well, its not quiet that easy.

Many people get contaminated computer programs by trading programs with other people. Others get contaminated computer programs through the use of modems, which allow computers to communicate over telephone lines (ie. The Internet)

Most of the time, programs that arrive by modem or a trade are perfectly safe to use. However, you do stand a chance of getting a program that has been tampered with. Here a computer program virus is hiding inside the normal program. Many computer programs that are traded were copied illegally.

When this program enters your computer through your input device, it hides in your computer’s memory and starts to duplicate itself like a disease. When you save your data, you also save the virus. Slowly but surely, the virus crowds out your data and causes major system problems.

The virus can’t affect the computer’s ROM (Read Only Memory), but it can affect RAM (Random Access Memory) and your computer disks. When your shut off your computer a virus that has been picked up will be lost, just like any other memory that is held in RAM.

   

    If the virus is on your disk or hard drive, it will return to the computer when you use the program again. If you switch from one program to another without shutting down the machine, the virus will attach itself to the new program. In this way, it can slowly infect all your programs before you know that it exists. Today millions of dollars are being spent to rid and protect computer systems from these virus programs.

Commercial and shareware programs have been created with the sole purpose of detecting and fixing suspect programs that might be viruses infected. These detection programs should be ran when any disk is put into your disk drive or every time your computer is first started up each day to scan the computer’s hard drive.

Computers Strikes The World!

Have you used a computer recently? Chances are you have. If you have made a phone call, ridden in a car, watched a TV, played a video game you have used a computer. Even as you read this paper, keep in mind the words you are reading were put into type by a computer.
Here is a list of statements about computers. Decide whether each statement is true or false .

1. Computers are smarter than humans.
2. Computers have brains.
3. Some computers have feelings.
4. Computers can solve any problems.
5. You need to know a lot of science and math to use a computer.

If you decided that each statement is false, you are correct. Then what is a computer? What can it do? It is a machine that can handle large amounts of information and work with amazing speed. A computer is built to do these four jobs:

Computers are conformed to follow instructions from humans. They can solve only the problems that people tell them to solve. Since people cannot solve every problem, neither can computers. To tell a computer what to do, you have to know what problem you want to solve and have a plan for solving it.

Since computers can’t do anything without instructions from a human, what makes them so special? They can do some things better than humans. Computers calculate faster than humans. They are more accurate than humans. Computer can also store vast amounts of information, and they do not “forget” what they store. These kinds of qualities make computer wonderful tools to help people solve complex problems.

Computers have become important and valuable tools in today’s world. Since they affect so many parts of our lives, it is important to be aware of how they are used and how they work.

Web Blogging (In Demand)

A blog (a portmanteau of web blog) is a website where entries are written in chronological order and commonly displayed in reverse chronological order. “Blog” can also be used as a verb, meaning to maintain or add content to a blog. Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, image, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs.

According to Chris Ashley of IST- Interact University, the weblog is like a journal because it is a dynamic and continually updated site that grows over time with the accumulation of writing and other content. Typically, web blogging,takes place within a community of other bloggers who share a common interest. These communities may be very loosely or closely associated, ranging, for example, from a circle of friends sharing day-to-day information, to a group of fifteen people working collaboratively on a project, or to hundreds of people who share a larger interest. For the most part of the community is a primary audience, and the web blogger quite likely haw two roles, being both a writer for this community and an audience member of the other community members’ web blogs which point to, comment on, and reference each other.

This site is easy to navigate. You can begin blogging be easily registering and creating a site. You can post your own thoughts, ideas, reflections, observations and even comment on news. Some web bloggers return to the site throughout the day to add, edit, update and revise.

Web blogging is also very important in business because you don’t need to go to your client. Instead, they will just browse your website and they will know everything they want to know about your business. If they have questions or comment they’ll just leave there.

A web blog is a web-based writing space. It is where an individual uses to write everyday. This is a writing tool that supports practicing writers and non writers. In that case you will gain a lot of information, answer some of your questions and also entertains you. It will enhance your thinking ability to understand the everyday happenings. Gives you a lesson to apply in your lives and be a better person.

Afterwards letters has been produced wherein with just your paper and pencil, you can already inform people. And to know its reply, you will wait for his letter for a feedback.
