The evolution of computers goes long back ago and its very interesting as well as quite important for understanding the working of computer.
Long back about 4ooB.c first every computing instrument was developed which can add and subtract. graduaklly afterwards there was importance of an computing instrument. pascal first computer came in 1642and other scientist loike napiers and leibnitz done significant work in this field which eventually led to present day computer. MARK-1 was the first modern computer. British mathematician AUGUSTA ADA BYRON was the first ever programmer. BASIC was introduced in 1965. IBM pc was introduced in 1981. First graphical computer “MAC” came in 1984 and microsoft was introduced in 1985. windows 3.1 become most popular in 1992 bthe first general computer was ENIAC( ELECTRONIC NUMERICAL INTEGRATOR AND CALCULATOR). JOHN VON NEUMAN gave the concept of stored program.

Computer hardware and software are two sides of the same coin. Computer hardware cannot function if it doesn’t have the necessary software to operate it. It will be just a piece of junk without the support of the required software. Computer Software is of 3 types:
System Software helps in running the computer hardware and computer system. It helps to shield the programmer to a great extent from the details of the particular computer hardware or system being used, especially memory and other accessory devices like printers, readers, communications, displays, keyboards, displays,

No matter who you are and what you do today the use of a computer is vital to your success. With increasing technological advances and direct connection of the entire world through networks, the web, and various lines of communication, using computers is becoming the way of life. With all its benefits come the problems associated with it. Granted the pros out-weigh the cons, it is still evident that nothing good comes easy. That is why so much malware is constantly revealing itself through our computerized world. Malware is short for malicious software and is typically used as a catch-all term to refer to any software designed to cause damage to a single computer, server, or computer network, whether it is a virus, spyware, and or anything harmful to your computer. We all know that viruses, just as in the medicinal world, can quickly spread and evolve as it cleverly finds ways to inflict damage of some sort to any computer (most times accidental). Viruses are computer programs or scripts that attempt to spread from one file to another on a single computer and/or from one computer to another, using a variety of methods, without the knowledge and consent of the computer user. This makes it hard to predict because most users have no idea that they are sending and receiving viruses. The most significant characteristic of a virus is that it spreads itself most commonly through emails.
