Supercomputers are the fastest and the most expensive computers. These huge computers are used to solve very complex science and engineering problems.

Information can be transmitted over different types of electrical cables. Also, you will learn about the most common types of protocols used by the network models while communicating one system with another. Computer networks are used to share files and data between computers like sharing file in office or sharing file from one city to other city.

4 Examples of Different Computer Types

An Operating System OS is a software that acts as an interface between computer hardware components and the user. Every computer system must have at least one operating system to run other programs. The OS helps you to communicate with the computer without knowing how to speak the computer's language. It is not possible for the user to use any computer or mobile device without having an operating system. To speed the same process, a job with a similar type of needs are batched together and run as a group.

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 differ based on their data processing abilities. They are classified according to purpose, data handling and functionality. According to purpose, computers are either general purpose or specific purpose. General purpose computers are designed to perform a range of tasks. They have the ability to store numerous programs, but lack in speed and efficiency.

What is Computer? Types of Computer

On the basis of data handling capabilities , the computer is of three types:. Analogue computers are designed to process analogue data. Analogue data is continuous data that changes continuously and cannot have discrete values. We can say that analogue computers are used where we don't need exact values always such as speed, temperature, pressure and current. Analogue computers directly accept the data from the measuring device without first converting it into numbers and codes. They measure the continuous changes in physical quantity and generally render output as a reading on a dial or scale.

What is Computer Bus: The electrically conducting path along which data is transmitted inside any digital electronic device. Each wire carries just one bit, so the number of wires determines the largest data WORD the bus can transmit: a bus with eight wires can carry only 8-bit data words, and hence defines the device as an 8-bit device. A computer bus normally has a single word memory circuit called a LATCH attached to either end, which briefly stores the word being transmitted and ensures that each bit has settled to its intended state before its value is transmitted. The Computer bus helps the various parts of the PC communicate. If there was no bus, you would have an unwieldy number of wires connecting every part to every other part. It would be like having separate wiring for every light bulb and socket in your house.

Primary Memory This is the main memory of the computer. This type of RAM is a volatile memory that needs to be refreshed with voltage regularly. Each of those act as the working storage of every computer, with DRAM serving as the main memory and SRAM being used for high-speed caches and buffers. Semiconductor memory is used in all forms of computer applications: there are many types and technologies that are used. Primary memory is further divided in two types: 1.

Classification of Computers | Type of Computer

A computer is one type of machine manage different kinds of programs to perform useful tasks to the users. Computer gives proper response to the users through the set of instructions arranged in proper order. It has storage capacity along with execution benefits. Computers can perform both complex and simple operations.

We have four different computer types classified according to their performance, power, and size. A computer is an electronic device that accepts data, processes it, stores data, and then produces an output.

 - Я кое о чем тебе не рассказал. Иной раз человек в моем положении… - Он замялся, словно принимая трудное решение.  - Иногда человек в моем положении вынужден лгать людям, которых любит. Сегодня как раз такой день.  - В глазах его читалась печаль.  - То, что сейчас скажу, я не собирался говорить никому.

Стратмор сощурил. - А ты как думаешь. И уже мгновение спустя ее осенило. Ее глаза расширились. Стратмор кивнул: - Танкадо хотел от него избавиться.

Файлы, содержащие программы, незнакомые устройству, немедленно отвергались.

Директорские апартаменты. В этот субботний вечер в Коридоре красного дерева было пусто, все служащие давно разошлись по домам, чтобы предаться излюбленным развлечениям влиятельных людей. Хотя Бринкерхофф всегда мечтал о настоящей карьере в агентстве, он вынужден был довольствоваться положением личного помощника - бюрократическим тупиком, в который его загнала политическая крысиная возня. Тот факт, что он работал рядом с самым влиятельным человеком во всем американском разведывательном сообществе, служил ему малым утешением.

Это личный кабинет директора. - Это где-то здесь, - пробормотала она, вглядываясь в текст.  - Стратмор обошел фильтры.

Сьюзан, увидев, что дело пошло, попыталась помочь Стратмору. Дверь приоткрылась на несколько сантиметров. Они держали ее что было сил, но сопротивление оказалось чересчур сильным и створки снова сомкнулись. - Подождите, - сказала Сьюзан, меняя позицию и придвигаясь ближе.

В АНБ он получил кличку Джабба и приобрел репутацию полубога. Он бродил по коридорам шифровалки, тушил бесконечные виртуальные пожары и проклинал слабоумие нерадивых невежд. Чатрукьян знал: как только Джабба узнает, что Стратмор обошел фильтры, разразится скандал.

Мидж смотрела на цифры, не веря своим глазам.
