The most powerful computers in terms of performance and data processing are the Supercomputers. A supercomputer is pretty much exactly what it sounds like.

Introduction to Computing. Since the advent of the first computer different types and sizes of computers are offering different services. The most powerful computers in terms of performance and data processing are the Supercomputers. These are specialized and task specific computers used by large organizations. These computers are used for research and exploration purposes, like NASA uses supercomputers for launching space shuttles, controlling them and for space exploration purpose.

Four types of computers

A computer is most imaginary machine that manages the many different types of instructions which are given by user, finally produce the accurate output for user. Computer is able to perform all types of simple and complex operations. There are 4 types of computers with their classification such as:. In old days, large enterprises and organizations used the supercomputer because they required large-scale computing power. A supercomputer is architectural and operational totally depend on parallel and grid processing, because with the help of thousand of processor all processes are executed simultaneously.

A computer is a machine that accepts data as input, processes that data using programs, and outputs the processed data as information. Many computers can store and retrieve information using hard drives. Computers can be connected together to form networks, allowing connected computers to communicate with each other. The two principal characteristics of a computer are: It responds to a specific instruction set in a well-defined manner and it can execute a prerecorded list of instructions call a program. There are four main processing steps in a computer: inputting , storage , outputting and processing. Modern computers can do billions of calculations in a second. Being able to calculate many times per second allows modern computers to multi-task, which means they can do many different tasks at the same time.

4 Examples of Different Computer Types

Supercomputers are the fastest and the most expensive computers. These huge computers are used to solve very complex science and engineering problems. Supercomputers get their processing power by taking advantage of parallel processing ; they use lots of CPUs at the same time on one problem. A typical supercomputer can do up to ten trillion individual calculations every second. Example Supercomputers:. Mainframe colloquially, "big iron" computers are similar to supercomputers in many aspects, the main difference between them is the fact that a supercomputer uses all its raw power to focus on very few tasks, while a mainframe perform thousands or millions of operations concurrently. Due to its nature, mainframes are often employed by large organizations for bulk data processing, such as census , industry and consumer statistics, enterprise resource planning and transaction processing.

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.

Mainframe computer

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.

A mainframe computer , informally called a mainframe or big iron , [1] is a computer used primarily by large organizations for critical applications, bulk data processing such as the census and industry and consumer statistics , enterprise resource planning , and large-scale transaction processing. A mainframe computer is larger and has more processing power than some other classes of computers, such as minicomputers , servers , workstations , and personal computers. Most large-scale computer-system architectures were established in the s, but they continue to evolve. Mainframe computers are often used as servers.

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.

Alfred is a long-time teacher and computer enthusiast who works with and troubleshoots a wide range of computing devices. Google exec Amanda Rosenberg modeling Google Glass which fall under the small size computers. By Max Braun. The different types of computers can be grouped into six major categories according to size. Each category excels at specific functions. Generally, the size of the computer determines the processing abilities.

 Спальня, - без колебаний отозвался. Сьюзан смутилась. - Хорошо, а что, если… кошка. - Жила! - не задумываясь выпалил Беккер. - Жила.

 - Она не дала ему договорить. Бринкерхофф почти физически ощущал, как интенсивно работают клеточки ее мозга. - Помнишь, что случилось в прошлом году, когда Стратмор занимался антисемитской террористической группой в Калифорнии? - напомнила. Бринкерхофф кивнул.

 Тебе следовало бы работать в полиции, - улыбнулся Стратмор.  - Идея неплохая, но на каждое послание Танкадо, увы, поступает ответ. Танкадо пишет, его партнер отвечает. - Убедительно.

 - Они все… - Красно-бело-синие? - подсказал парень. Беккер кивнул, стараясь не смотреть на серебряную дужку в верхней губе парня.

Она встала, но ноги ее не слушались. Надо было ударить Хейла посильнее. Она посмотрела на беретту и внезапно почувствовала тошноту. - Вы действительно собираетесь пристрелить Грега Хейла.

 Это многое объясняет, - настаивала.  - Например, почему он провел там всю ночь. - Заражал вирусами свое любимое детище. - Нет, - сказала она раздраженно.  - Старался спрятать концы в воду, скрыть собственный просчет.

Чуть впереди, у остановки, притормозил городской автобус. Беккер поднял. Дверцы автобуса открылись, но из него никто не вышел. Дизельный двигатель взревел, набирая обороты, и в тот момент, когда автобус уже готов был тронуться, из соседнего бара выскочили трое молодых людей. Они бежали за уже движущимся автобусом, крича и размахивая руками.

Он заберет личные вещи Танкадо и вернется домой. Разве это не услуга. Сьюзан промолчала. Она поняла: все дело в деньгах.
