Computer

Computer is a great wonder of science. Charles Babbage, an English mechanical engineer and polymath, discovered the concept of a programmable computer. He is considered the “father of the computer”. But it is modified day by day. Now a days we get laptop,notebook,probook etc. It help us a lot. We can carry this product and be benifited. Every person are interested about it.

There are two units in computer the input unit and the output unit. During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated manual computers. Hardware and software also two parts of a computer. The term hardware means all of those parts of a computer that are tangible physical objects. Circuits, computer chips, graphic cards, sound cards, memory (RAM), motherboard, displays, power supplies, cables, keyboards, printers and “mice” input devices are all hardware.

 

The principle of the modern computer was made by Alan Turing in his seminal 1936 paper, On Computable Numbers. Software refers to parts of the computer which do not have a material form, such as programs, data, protocols, etc. Software is that part of a computer system that consists of encoded information or computer instructions, in contrast to theĀ  hardware from which the system is built. The benefits of computer is very good.
