adds,subtracts,multiplies,divides,and does comparisons.These comparisons,which are basically“less than",“greater than”,and“equal to”,can be combined into several common expressions,such as "greater than or equal to".The objective of most instructions that use comparisons is to determine which instruction should be executed next.

Virus attacks are growing rapidly these days.According to Business Week,the 76,404 attacks reported in the first half of 2003 nearly match previous year's total number.As new antivirus tools are more powerful than before,the virus writers are getting a lot smarter with newer and creative ways to attack network systems.Let's first examine some common virus types: Basic Virus-a piece of software code that is developed to attack computers and network systems via email or Internet connections.It quickly replicates itself and gradually attaches to files,programs or the hard drive. Trojan Horses-This is a program that doesn't replicate when entering a system but can be effectively used to open'back doors.'Trojan Horses allow hackers to take control over a particular system or to steal very important data.

Since it is very difficult to avoid the virus,your best defense is a powerful antivirus program.In order to fight with such viruses,the software vendors should focus on making their products more robust.This may ask for a trade-off between user-friendliness and security.In specific cases it may require line-by-line inspection,code retooling and even systems automation to defend the installed programs.
