Computer: A computer is a combination of hardware and software resources which integrate together and provides various functionalities to the user. Hardware are the physical components of a computer like the processor, memory devices, monitor, keyboard etc. There are a few basic components that aids the working-cycle of a computer i. It needs certain input, processes that input and produces the desired output. The input unit takes the input, the central processing unit does the processing of data and the output unit produces the output. The memory unit holds the data and instructions during the processing. Digital Computer: A digital computer can be defined as a programmable machine which reads the binary data passed as instructions, processes this binary data, and displays a calculated digital output.

The set of instruction is presented to the computer in the form of raw data which is entered through input devices such as keyboard or mouse. Later this set of instructions is processed with the help of CPU [Central Processing Unit], and the computer system produces an output with the help of output devices like printers and monitors. A large amount of data is stored in the computer memory with the help of primary and secondary storage devices temporarily and permanently. This is called as storage devices.

A computer can process data, pictures, sound and graphics. They can solve highly complicated problems quickly and accurately. A computer as shown in Fig. These are. We discuss below each of these Computer operation. Input: This is the process of entering data and programs in to the computer system. You should know that computer is an electronic machine like any other machine which takes as inputs raw data and performs some processing giving out processed data.

Home Computer Fundamentals Block Diagram of Computer A Block diagram of a computer displays a structural representation of a computer system. The block diagram gives you a quick overview of the working process of a computer from inputting the data to retrieving the desired results. These devices are used to input information or instruction into the computer system. Like other electronic machines, a computer takes inputs as raw data binary data and performs necessary processing giving out processed data. Therefore, the input unit is the medium of communication that takes data from us to the computer in an organized manner for processing.

Block diagram of a computer gives you the pictorial representation of a computer that how it works inside. Or you can say that, in computer's block diagram, we will see how computer works from feeding the data to getting the result. All major calculation and comparisons are made inside the CPU and it is also responsible for activation and controlling the operation of other unit. Here arithmetic logic unit performs all arithmetic operations such as addition, subtraction, multiplication and division. It also uses logic operation for comparison.

So a computer is normally considered to be a calculating device that performs arithmetic operations at enormous speed. A computer is an electronic device which is used to perform operation on raw data as per instruction given by user. Like any other device or machine, a computer system has also a number of parts. A computer system can be blocked into mainly three parts:.

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. Block diagrams are typically used for higher level, less detailed descriptions that are intended to clarify overall concepts without concern for the details of implementation. Contrast this with the schematic diagrams and layout diagrams used in electrical engineering, which show the implementation details of electrical components and physical construction.

What is a Computer System Unit? A computer system unit is the enclosure that contains the main components of a computer. It is also referred to as a computer case or tower. Definition A typical desktop computer consists of a computer system unit, a keyboard, a mouse, and a monitor. The computer system unit is the enclosure for all the other main interior components of a computer. It is also called the computer case, computer chassis, or computer tower.

Интересно, увидит ли пилот лирджета, что он подъезжает. Есть ли у него оружие. Откроет ли он вовремя дверцу кабины. Но, приблизившись к освещенному пространству открытого ангара, Беккер понял, что его вопросы лишены всякого смысла. Внутри не было никакого лирджета. Он несколько раз моргнул затуманенными глазами, надеясь, что это лишь галлюцинация.

После разговора со Стратмором она начала беспокоиться о безопасности Дэвида, а ее воображение рисовало страшные картины. - Ну, - послышался голос Хейла, склонившегося над своим компьютером, - и чего же хотел Стратмор. Провести романтический вечер в обществе своего главного криптографа. Сьюзан проигнорировала его вопрос и села за свой терминал. Ввела личный код, и экран тотчас ожил, показав, что Следопыт работает, хотя и не дал пока никакой информации о Северной Дакоте. Черт возьми, - подумала Сьюзан.

ГЛАВА 51 Джабба был похож на гигантского головастика. Подобно киноперсонажу, в честь которого он и получил свое прозвище, его тело представляло собой шар, лишенный всякой растительности. В качестве штатного ангела-хранителя компьютерных систем АН Б Джабба ходил по отделам, делал замечания, что-то налаживал и тем самым постоянно подтверждал свое кредо, гласившее, что профилактика-лучшее лекарство. Ни один из поднадзорных ему компьютеров АНБ не заразился вирусом, и он был намерен не допустить этого и впредь. Рабочим местом Джаббы была платформа, с которой открывался вид на подземную сверхсекретную базу данных АНБ.

Шифр, подумала. Кабинет постепенно утопал в дыму. Стало трудно дышать. Сьюзан бессильно прижалась к двери, за которой, всего в нескольких сантиметрах от нее, работала вентиляция, и упала, задыхаясь и судорожно хватая ртом воздух. Сьюзан закрыла глаза, но ее снова вывел из забытья голос Дэвида.
