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. Sure, most computers have their own distinct design - and different brands of hardware installed - but the components listed above are standard across all computers.

Computer hardware and software

Von-Neumann computer consists of two main components: memory and CPU. This concept has not yet been overcome and even the latest computers still come from von-Neumann architecture. An application software is a computer program designed to perform a group of coordinated functions, tasks, or activities. Applications may be connected with the computer and its system software or may be published separately, and may be coded as proprietary or open-source. Operating system is defined as a system software that manages computer hardware and software resources and provides common services for computer programs.

Digital computer , any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code —i. By counting, comparing, and manipulating these digits or their combinations according to a set of instructions held in its memory , a digital computer can perform such tasks as to control industrial processes and regulate the operations of machines; analyze and organize vast amounts of business data; and simulate the behaviour of dynamic systems e. A brief treatment of digital computers follows. For full treatment, see computer science: Basic computer components. A typical digital computer system has four basic functional elements: 1 input-output equipment , 2 main memory , 3 control unit, and 4 arithmetic-logic unit.

Hardware refers to the physical, tangible computer equipment and devices, which provide support for major functions such as input, processing internal storage, computation and control , output, secondary storage for data and programs , and communication. A computer system is a set of integrated devices that input, output, process, and store data and information. Computer systems are currently built around at least one digital processing device. There are five main hardware components in a computer system: Input, Processing, Storage, Output and Communication devices. Are devices used for entering data or instructions to the central processing unit. Are classifie according to the method they use to enter data. Keyboard similar to a typewriter is the main input device of a computer.

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 computer age introduced a new element to businesses, universities, and a multitude of other organizations: a set of components called the information system , which deals with collecting and organizing data and information. An information system is described as having five components. This is the physical technology that works with information. Hardware can be as small as a smartphone that fits in a pocket or as large as a supercomputer that fills a building.

A computer is a complex machine. While most of it works on a microscopic level, it certainly has recognizable macroscopic components that contribute to its uses. A computer can be used to do just about anything from simple calculations to preparing reports to sending rockets into space to simulating the spread of cancer in body organs. And yet, for all that complexity, the building blocks of the average computer are easy enough for anyone to understand.

ГЛАВА 43 В свои сорок пять Чед Бринкерхофф отличался тем, что носил тщательно отутюженные костюмы, был всегда аккуратно причесан и прекрасно информирован. На легком летнем костюме, как и на загорелой коже, не было ни морщинки. Его густые волосы имели натуральный песочный оттенок, а глаза отливали яркой голубизной, которая только усиливалась слегка тонированными контактными линзами. Оглядывая свой роскошно меблированный кабинет, он думал о том, что достиг потолка в структуре АНБ. Его кабинет находился на девятом этаже - в так называемом Коридоре красного дерева. Кабинет номер 9А197. Директорские апартаменты.

 - Какой смысл хлестать мертвую кобылу. Парень был уже мертв, когда прибыла скорая. Они пощупали пульс и увезли его, оставив меня один на один с этим идиотом-полицейским.

Эти числа отлично работают при создании шифров, потому что компьютеры не могут угадать их с помощью обычного числового дерева. Соши даже подпрыгнула. - Да.

Росио покачала головой: - Это. Но вам ее не найти. Севилья - город большой и очень обманчивый. - Я постараюсь.  - Вопрос национальной безопасности… - Если вам не повезет, - сказала Росио, бросив взгляд на пухлый конверт, выпирающий в кармане Беккера, - пожалуйста, заходите.

    (1) Scanner: An input device that can convert the contents of a paper document into a digital image that can be stored in the computer. (2) CPU (Central Processing Unit) or the processor: The "brain" of the computer where programs are run. It is one of the most expensive parts of the hardware.
