Classification of the computer on the basis of brand
Computers can be classified into various classes according to on the basis of working principle, on the basis of size, on the basis of brand. On the basis of brand computers are classified in to three types IBM PC, IBM compatible, Apple/Macintosh.
The computers manufactured by IBM (International Business Machine) company are called IBM computers. The microcomputers of IBM companies are called IBM PC. IBM is one of the leading companies in computer industry. Computers developed on the principle of IBM computers are called IBM Compatible. It can perform all the tasks that an IBM computer does.

Classification of computer based on size
Computer can be classified into four categories based on size namely Micro, Mini, Mainframe and Super computer. Micro computers are smallest and based on the use of microprocessors. Microprocessor is combined or integrated circuit which contains all the elements of processing. Smaller than mainframe and have lowspeed, low storage capacity. Basically used for small businessapplication are known as home computers.
Minicomputers are little larger than micro computes also use samemicroprocessor but with more speed. They can be lined with other systems to form network. Support multiuser and multi task. These are used in business and commerce such as payroll, stock control.
Mainframe computer can handle hundreds of users at same time because of high speed and large memory. They are designed for distributing system . Data is physically separate but logically they are treated as one unit. These...
