A computer is any machine that can be programmed to carry out a set of algorithms and arithmetic instructions. In terms of construction, each of these main components are attached to the motherboard and then put into a protective case—resembling the clean, polished look most of us are accustomed to seeing.

The basic parts of a desktop computer are the computer case , monitor , keyboard , mouse , and power cord. Each part plays an important role whenever you use a computer. Looking for the old version of this video?

The legacies of earlier designs, such as Babbage's difference engine and the mainframe punch card systems of the s, have a significant impact on today's computer systems. In my first article in this historical series, Computer history and modern computers for sysadmins , I discussed several precursors to the modern computer and listed characteristics that define what we call a computer today.

A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. A "complete" computer including the hardware , the operating system main software , and peripheral equipment required and used for "full" operation can be referred to as a computer system. This term may as well be used for a group of computers that are connected and work together, in particular a computer network or computer cluster. Computers are used as control systems for a wide variety of industrial and consumer devices. This includes simple special-purpose devices like microwave ovens and remote controls , factory devices such as industrial robots and computer-aided design , and also general-purpose devices like personal computers and mobile devices such as smartphones.

Computers internal architectural design comes in different types and sizes, but the basic structure remains same of all computer systems. Devices that are not integral part of CPU referred to as peripherals. The below section describe briefly all the computer components in a computer system. All the input unit devices provide the instructions and data are transformed into binary codes that is the primary memory acceptable format. Memory or Storage unit is used for storing Data during before and after processing. The capacity of storage is expressed in terms of Bytes. The two terms Memory or Storage unit are used interchangeably, so it is important to understand what is the difference between memory and storage?

Любое правительство выложит любые деньги. Можешь ли ты представить себе, как мы будем докладываем президенту, что перехватили сообщения иракцев, но не в состоянии их прочитать. И дело тут не только в АНБ, речь идет обо всем разведывательном сообществе. Наша машина обеспечивает информацией ФБР, ЦРУ, Агентство по борьбе с наркотиками - всем им теперь придется действовать вслепую.
