On the basis of data handling capabilities , the computer is of three types:.

Mainframes are designed to process large volumes of data at high speed.

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.

List of computer size categories

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.

Four types of computers

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.

Introduction To Computers – Technology Applications. There are a lot of terms used to describe computers. Do you know the different types of computers? PC​.

4 Examples of Different Computer Types

There are four different types of computers which vary according to their size, power and performance. Depending on the kind of task you would want to perform, a computer is usually the best tool for you. People use computers for different reasons depending on their needs. For instance, simple users such as students use these electronic brains for learning and research, while advanced users like data analysts use computers for processing complex permutations and analysis to derive meanings. As such, computers are created for particular reasons and applications.

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.

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.

another. II, Computer sizes and power. Computers can be generally classified by size and power programs as fast as possible, whereas a mainframe uses its power to execute many but there are many variations on these two basic types.
