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.

Computer hardware and software

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. This is by no means intended to be an invitation to disassemble your computer, nor is it a set of instructions to do so. Without the proper knowledge, you can severely damage your computer, and importantly, doing so is unsafe. What it is : All components of a computer communicate through a circuit board called the motherboard, as was mentioned above. It fetches, decodes, and executes these instructions.

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.

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.

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 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.

Arithmetic Logic Unit (ALU)

Черт возьми! - снова мысленно выругался.  - Никакая это не паранойя. Этот чертов компьютер бьется над чем-то уже восемнадцать часов. Конечно же, все дело в вирусе. Чатрукьян это чувствовал. У него не было сомнений относительно того, что произошло: Стратмор совершил ошибку, обойдя фильтры, и теперь пытался скрыть этот факт глупой версией о диагностике. Чатрукьян не был бы так раздражен, если бы ТРАНСТЕКСТ был его единственной заботой.

 Я не хочу никоим образом нарушать покой директора и говорить с ним о кризисе, в то время как он не в состоянии предпринять хоть что-нибудь. Сьюзан понимала, что коммандер прав. Даже в такие моменты ему удавалось сохранять ясность рассудка. - А вы не думали о том, чтобы позвонить президенту. Стратмор кивнул: - Думал.

Скоростной карт фирмы Кенсингтон повернул за угол и остановился. Сзади, перпендикулярно туннелю, начинался коридор, едва освещаемый красными лампочками, вмонтированными в пол. - Пойдемте, - позвал Бринкерхофф, помогая Сьюзан вылезти. Она шла следом за ним точно в тумане. Коридор, выложенный кафельными плитками, довольно круто спускался вниз, и Сьюзан держалась за перила, стараясь не отставать. Воздух в помещении становился все прохладнее. Чем глубже под землю уходил коридор, тем уже он становился.

Такая красивая женщина пошла бы с этим типом, только если бы ей хорошо заплатили. Боже. Такой жирный. Крикливый, тучный, мерзкий немец! - Клушар заморгал, стараясь переменить положение, и, не обращая внимания на боль, продолжал: - Ну чистая скотина, килограмм сто двадцать, не меньше. Он вцепился в эту красотку так, словно боялся, что она сбежит, - и я бы ее отлично понял.

Он запаникует и в конце концов, столкнувшись с группой вооруженных людей, ничего не сможет поделать. После минутного упорства ему придется уступить. Но если я вызову агентов безопасности, весь мой план рухнет, - подумал .

    (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.
