4 Examples of Different Computer Types

This list of computer size categories attempts to list commonly used categories of computer by the physical size of the device and its chassis or case, in descending order of size. One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has value, as it provides a ranked categorization of devices. It also ranks some more obscure computer sizes. There are different sizes like-mini computers, microcomputer, mainframe computer and super computer. The classes above are not rigid; there are "edge devices" in most of them. For instance, the "subnotebook" category can usually be distinguished from the "PDA" category because a subnotebook has a keyboard and a PDA has not; however, tablet PCs may be larger than subnotebooks making it seemingly correct to classify them as laptops and also lack a keyboard, while devices such as the Handspring Treo have something that might charitably be called a keyboard, but are still definitely in the "smartphone" category.

Patrick, a computer technician, is a dedicated writer who wishes to make the world better by informing individuals who seek more knowledge. Wikimedia Commons. 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. In this article, we are going to have a look at the differences between super, mainframe, mini, and microcomputers.

Mainframes are designed to process large volumes of data at high speed. They are used by large businesses such as. A desktop computer is the most common kind of PC. It is a collection of a number of different hardware devices. This type of computer is sited permanently on a desk because its design means it cannot be easily moved.

Before getting into the detail, it is essential to understand the concept of Computer System. Computer System is a general purpose device which can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operation can be readily changed, the computer can solve more than one kind of problems. In this assignment I will work on the following four different phases. Each phase will cover the related content in detail.

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.

Types of Computer

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.

2. Mainframe computers

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.

Generally, the size of the computer determines the processing abilities.

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. Supercomputer mostly implemented in large scale scientific and engineering areas, because where required maintenance for large amount of database. Mainframe Computer.

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.  - Хорошо, теперь давайте. Дверь снова приоткрылась на дюйм.

Теперь пользователь мог посылать конфиденциальные сообщения: ведь если даже его послание перехватывалось, расшифровать его могли лишь те, кто знал ключ-пароль. АНБ сразу же осознало, что возникла кризисная ситуация. Коды, с которыми столкнулось агентство, больше не были шифрами, что разгадывают с помощью карандаша и листка бумаги в клетку, - теперь это были компьютеризированные функции запутывания, основанные на теории хаоса и использующие множественные символические алфавиты, чтобы преобразовать сообщение в абсолютно хаотичный набор знаков.

Он должен был бы удариться в панику, но этого не произошло: он точно знал, куда держит путь. Свернув влево, на Менендес-пелайо, он прибавил газу. Мотоцикл пересек крохотный парк и выкатил на булыжную мостовую Матеус-Гаго - узенькую улицу с односторонним движением, ведущую к порталу Баррио - Санта-Крус. Еще чуть-чуть, подумал .

Дэвид Беккер исчез, но это ненадолго. Из всех севильских автобусов мистер Беккер выбрал пользующийся дурной славой 27-й маршрут. Автобус номер 27 следует к хорошо известной конечной остановке.

Терпи, - сказал он.  - Терпи. Потом закрыл глаза и глубоко вздохнул.
