Functions of computers.
Computer can perform many functions: they can do
mathematical and logical operations, mathematical
operations including arithmetic and algebraic operations,
such as addition, subtraction, multiplication and division,
raising to a power, selecting, sorting and matching.
Computers are divided into four main classes:
microcomputers, minicomputers, mainframes and
supercomputers.
A minicomputer is a computer manufactured on a single
printed board which contains one or more chips. Most
computers are personal computers. At present personal
computers have become so powerful that they are used
as CAD/ CAM systems.
4. A microprocessor is a very small device used in
microcomputers, which deals with memories by reading
and writing process. Microprocessors can obtain from
memory and execute a limited set of instructions in
order to perform addition or subtraction on a binary
word and to input or output binary data.
5. Memory is a device for storing digital information.
Memory should be small in size and large in capacity. It
should take little power and work at the same speed as
computer logic. There are many types of memories. All
microcomputers use Random Access Memory (RAM)
and Read Only Memory (ROM).
6. RAM is called so because information can be put into
or out of any single byte of memory. ROM is permanent
memory for program storage.
7. People know many types of memory units, hard disks
and floppy disks being widely used. Floppy disks
(flexible plastic disks) are used in personal computers.
