A BASIC GUIDE TO THE INTERNET

The Internet is a computer network made up of thousands of networks worldwide. No one knows exactly how many computers are connected to the Internet. It is certain, however, that these number in the millions.

No one is in charge of the Internet. There are organizations which develop technical aspects of this network and set standards for creating applications on it, but no governing body is in control. The Internet backbone, through which Internet traffic flows, is owned by private companies.

All computers on the Internet communicate with one another using the Transmission Control Protocol/Internet Protocol suite, abbreviated to TCP/IP. Computers on the Internet use a client/server architecture. This means that the remote server machine provides files and services to the user's local client machine. Software can be installed on a client computer to take advantage of the latest access technology.

I. Introduction

Some basics and assumptions (the more you know, the more you UNDERSTAND):

Crossover cable: A crossover cable is needed to directly connect your computer and Xbox. You would plug one end of the cable to your computer and the other end into the Xbox, there are no devices in between. If you have a hub, switch, or router you will not need a crossover cable though some still will work with one. With connecting to hubs, switches, or routers you should use a straight-through cable.

HOW TO SAFEGUARD YOUR FILES WHEN COMPUTER CRASHES

First thing to keep in mind: If your computer hasn't crashed yet, it will in the future! So instead of waiting for fate to strike, take some precautions now:

2) Keep your computer healthy. Use an antivirus, an anti-spy, and a firewall. Keep them updated. Check regularly for Windows critical fixes.

3) Don't install software that would do dangerous things to your hard drive. A boot manager would fall in this category.

EVOLUTION OF COMPUTER VIRUSES HISTORY OF VIRUSES

part 1


Like any other field in computer science, viruses have evolved -a great deal indeed- over the years. In the series of press releases which start today, we will look at the origins and evolution of malicious code since it first appeared up to the present.

Going back to the origin of viruses, it was in 1949 that Mathematician John Von Neumann described self-replicating programs which could resemble computer viruses as they are known today. However, it was not until the 60s that we find the predecessor of current viruses. In that decade, a group of programmers developed a game called Core Wars, which could reproduce every time it was run, and even saturate the memory of other players’ computers. The creators of this peculiar game also created the first antivirus, an application named Reeper, which could destroy copies created by Core Wars.
