Computer virus, none have gained widespread acceptance or use this is a result of the difﬁculty in deﬁning precisely the characteristics of what a virus is and is not. A personal computer (pc) is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use pcs are intended to be operated directly by an end user, rather than by a computer expert or technician. A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously in the hierarchy that starts with a simple microprocessor (in watches, for example) at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers.
A mainframe computer is a big computer ibm builds mainframe computers today, a mainframe refers to ibm's system z servers many large corporations like banks, insurance companies, travel and retail sector, telecom companies process data on a mainframe. These computers are the cheapest among the other three types of computers the micro-computers are specially designed for general usage like entertainment, education and work purposes well known manufacturers of micro-computer are dell, apple, samsung, sony & toshiba.

The ibm system/360 mainframe computer sought to change that it could be ordered in a variety of models with different processing power, but each machine was compatible with the others, which meant applications developed for any one machine would work on any variant. Mainframe computers, created in the early 1940s, initially were bulky machines that required cooling-sensitive rooms the 1951 univac was the size of a one-car garage -- unheard of in the 21st century where small, mobile and fast is the norm.
Computer matching is the use of computers to screen and match data about individual characteristics provided by a variety of computer-based information systems and databases in order to identify individuals for business, government, or other purposes. A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (cpu) it includes a microprocessor, memory, and minimal input/output (i/o) circuitry mounted on a single printed circuit board.
