Classification of computer according to its size?

Answer 1

According to size

• Supercomputers

• Mainframe Computers

• Minicomputers

• Workstations

• Microcomputers, or Personal Computers

Supercomputers : are widely used in scientific applications such as aerodynamic design simulation, processing of geological data.

• Supercomputers are the most powerful computers. They are used for problems requiring complex calculations.

• Because of their size and expense, supercomputers are relatively rare.

• Supercomputers are used by universities, government agencies, and large businesses.

Mainframe Computers: are usually slower, less powerful and less expensive than supercomputers. A technique that allows many people at terminals, to access the same computer at one time is called time sharing. Mainframes are used by banks and many business to update inventory etc.

• Mainframe computers can support hundreds or thousands of users, handling massive amounts of input, output, and storage.

• Mainframe computers are used in large organizations where many users need access to shared data and programs.

• Mainframes are also used as e-commerce servers, handling transactions over the Internet.

Minicomputers: are smaller than mainframe, general purpose computers, and give computing power without adding the prohibitive expenses associated with larger systems. It is generally easier to use.

• Minicomputers usually have multiple terminals.

• Minicomputers may be used as network servers and internet servers.

Workstations

• Workstations are powerful single-user computers.

• Workstations are used for tasks that require a great deal of number-crunching power, such as product design and computer animation.

• Workstations are often used as network and Internet servers.

Microcomputers, or Personal Computers : is the smallest, least expensive of all the computers. Micro computers have smallest memory and less power, are physically smaller and permit fewer peripherals to be attached.

• Microcomputers are more commonly known as personal computers. The term "PC" is applied to IBM-PCs or compatible computers.

• Desktop computers are the most common type of PC.

• Notebook (laptop) computers are used by people who need the power of a desktop system, but also portability.

• Handheld PCs (such as PDAs) lack the power of a desktop or notebook PC, but offer features for users who need limited functions and small size.

They can also be classified in different ways like classification of computers by size. v Super computer

Super computers can process huge amounts of data, The biggest in size, the most expensive in price than any other is classified and known as super computer. It can process trillions of instructions in seconds. This computer is not used as a PC in a home neither by a student in a college. Governments specially use this type of computer for their different calculations and heavy jobs. Different industries also use this huge computer for designing their products. In most of the Hollywoods movies it is used for animation purposes. This kind of computer is also helpful for forecasting weather reports worldwide. v Mainframes

Another giant in computers after the super computer is Mainframe, which can also process millions of instructions per second and is capable of accessing billions of data. This computer is commonly used in big hospitals, air line reservation companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis. This is normally to expensive and out of reach from a salary-based person who wants a computer for his home. This kind of computer can cost thousands of dollars. v Minicomputer

This computer is next in line but offers less than mainframe in work and performance. These are the computers which are mostly preferred by the small type of business personals, colleges, etc. v Personal computers

Almost all the computer users are familiar with the personal computers. They normally know what the personal computer is and what are its functions. This is the computer mostly preferred by the home users. These computers are lesser in cost than the computers given above and also, small in size; they are also called PCs in short for Personal computers. This computer is small in size and you can easily arrange it to fit in your single bedroom with its all accommodation. Today this is thought to be the most popular computer in all. v Notebook computers

Having a small size and low weight the notebook is easy to carry to anywhere. A student can take it with him/her to his/her school in his/her bag with his/her book. This is easy to carry around and preferred by students and business people to meet their assignments and other necessary tasks. The approach of this computer is also the same as the Personal computer. It can store the same amount of data and having a memory of the same size as that of a personal computer. One can say that it is the replacement of personal desktop computer.
