what is computer?

Answer 1

A computer is a machine for manipulating data according to a list of instructions known as a program.

Computers are extremely versatile. In fact, they are universal information-processing machines. According to the Church–Turing thesis, a computer with a certain minimum threshold capability is in principle capable of performing the tasks of any other computer. Therefore, computers with capabilities ranging from those of a personal digital assistant to a supercomputer may all perform the same tasks, as long as time and memory capacity are not considerations. Therefore, the same computer designs may be adapted for tasks ranging from processing company payrolls to controlling unmanned spaceflights. Due to technological advancement, modern electronic computers are exponentially more capable than those of preceding generations (a phenomenon partially described by Moore's Law).

Computers take numerous physical forms. Early electronic computers were the size of a large room, while entire modern embedded computers may be smaller than a deck of playing cards. Even today, enormous computing facilities still exist for specialized scientific computation and for the transaction processing requirements of large organizations. Smaller computers designed for individual use are called personal computers. Along with its portable equivalent, the laptop computer, the personal computer is the ubiquitous information processing and communication tool, and is usually what is meant by "a computer". However, the most common form of computer in use today is the embedded computer. Embedded computers are usually relatively simple and physically small computers used to control another device. They may control machines from fighter aircraft to industrial robots to digital cameras.

Answer 2

. A device that accepts data, processes the data in accordance with a stored program, generates results, and usually consists of input, output, storage, arithmetic, logic, and control units. 2. A functional unit that can perform substantial computation, including numerous arithmetic operations or logic operations, without human intervention during a run. Note 1: This definition, approved by the Customs Council, distinguishes a computer from similar devices, such as hand-held calculators and certain types of control devices. Note 2: Computers have been loosely classified into microcomputers, minicomputers, and main-frame computers, based on their size. These distinctions are rapidly disappearing as the capabilities of even the smaller units have increased. Microcomputers now are usually more powerful and versatile than the minicomputers and the main-frame computers were a few years ago.

Answer 3

Any device capable of processing information to produce a desired result. No matter how large or small they are, computers typically perform their work in three well-defined steps: (1) accepting input, (2) processing the input according to predefined rules (programs), and (3) producing output.

Answer 4

Computer is a Electronic and Calculative device which is capable of formattig data. It runs according to Program(A set of instructuions) and it understands only Binary language(consists of aseries of 0's and 1's).

Answer 5

Computer is an electronic device for the storage and processing of information.

Answer 6

The litteral meaning of computer is :
an electronic machine that can store, find and arrange information,calculate amounts and control other machines.

Answer 7

It was a prehistoric animal that died 389 million years ago.It had 8 legs,2 heads,7 tails,and 4 mouths on each head and looked a little bit like beyonce knowles.

Answer 8

Computer is an automatic electronic machine which does subtraction, addition, multiplication, division and other functions.

Answer 9

it is a electronic device which process it and store it and give meaningful information
the various operation of a computer are :-
* input
* storage
* processing
* output
* control

Answer 10

I'll humour you....

Also called processor. an electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. Compare analog computer, digital computer.
2. a person who computes; computist.
