The data is normally stored in the computer’s memory and processed according to a set of instructions called a program stored in the computer’s memory.Computer is a machine that can be used for performing any type of calculations such as addition, subtraction, multiplication, division, etc.
What are the different types of Computers?
Depending upon the storage capacity of the computers, computers can be classified into two categories:
(A) Mainframe Computers:
Mainframe computers have large capacity storage as compared to that of the personal computers. Mainframe computers are a type of large, powerful computer. They operate on a different architecture than personal computers and have been around for much longer. Mainframes are often used for large-scale data processing, like compiling statistics and financial analysis.
(B) Personal Computers:
Personal computers are devices that can be customized to the user’s needs and abilities. The most common use for a PC is word processing, spreadsheets, emailing, and Internet surfing.
