Computer viruses have been around for quite a bit and nearly all of them have been spread through the Internet or its predecessors. Most viruses have been designed to steal users' information, processing power and/or disable the system all together.
The first computer virus, called "Creeper system", was an experimental self-replicating virus released in 1971. It was filling up the hard drive until a computer could not operate any further. This virus was created by BBN technologies in the US.
The first computer virus for MS-DOS was "Brain" and was released in 1986. It would overwrite the boot sector on the floppy disk and prevent the computer from booting. It was written by two brothers from Pakistan and was originally designed as a copy protection.
"The Morris" was the first Computer virus which spread extensively in the wild in 1988. It was written by Robert Morris, a graduate student from Cornell University who wanted to use it to determine the size of the internet. His approach used security holes in sendmail and other Unix applications as well as weak passwords, but due to a programming mistake it spread too fast and started to interfere with the normal operation of the computers. It infected around 15,000 computers in 15 hours, which back then was most of the internet.

Binary Number System: According to digital electronics and mathematics, a binary number is defined as a number that is expressed in the binary system or base 2 numeral system. It describes numeric values by two separate symbols; 1 (one) and 0 (zero). The base-2 system is the positional notation with 2 as a radix.
The binary system is applied internally by almost all latest computers and computer-based devices because of its direct implementation in electronic circuits using logic gates. Every digit is referred to as a bit.
