A computer is a programmable machine designed to sequentially and automatically
Carry out a sequence of arithmetic or logical operation .the particular sequence of
Operations can be changed readily , allowing the computer to solve more than one
Kind of problem . an important class of computer operations no some computing
Platforms is the accepting of input from human operators and the output of results
Formatted for human consumption . the interface between the computer and the
Human operators is as the user interface.

Conventionally a computer consists of some form of  memory for data storage, at
Least one element that carries out arithmetic and logic  operations ,and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from an external source ,and allow the results of operation to be sent out.

A computer is processing unit executes series of instructions make it read,
Manipulate and then store data. Conditional instructions change the sequence of
Instructions as a function of the current state of the machine or its environment
(1940-1945).originally, they were size of a large room, consuming as much
Power as several hundred modern computers (PCS).in this era mechanical
Analog computer were used for military application.

Modern computers based on integrated circuits are millions billions of time more
Capable than the early machines, and occupy a fraction of the space. Simple
Computer are small enough to fit into mobile devices, and mobile computers can be
Powered by small batteries. Personal computers in their various forms are icons of
The information age and are what most people think of as computers .however,
The embedded computers found in many devices from mp3 players to fighter aircraft
And from toys to industrial robots are the most numerous
