Types and Classification Of Computer

Types and Classification Of Computer

 A computer is a system that transforms facts into significant information. It procedures the enter according to the set of directions provided to it via the person and gives the desired output. Computers are of a range of kinds and they can be classified in two ways on the basis of measurement and on the groundwork of data dealing with capabilities.

So, on the groundwork of size, there are five kinds of computers: (Classification)

• Supercomputer
• Mainframe computer
• Minicomputer
• Workstation
• PC (Personal Computer)

And on the basis of data handling capabilities, there are three types of computer: (Types)

• Analogue Computer
• Digital Computer
• Hybrid Computer

Now let us discuss each type of computer in detail:

Supercomputer:

When we speak about speed, then the first name that comes to thinking when questioning of computer systems is supercomputers. They are the largest and quickest computers(in phrases of velocity of processing data). Supercomputers are designed such that they can procedure a huge quantity of data, like processing trillions of directions or information just in a second. This is due to the fact of the hundreds of interconnected processors in supercomputers. It is basically used in scientific and engineering functions such as climate forecasting, scientific simulations, and nuclear strength research. It was first developed by Roger Cray in 1976.

Characteristics of supercomputers:

• Supercomputers are the computers which are the fastest and they are additionally very expensive.
• It can calculate up to ten trillion individual calculations per second, this is also the reason which makes it even extra faster.
• It is used in the stock market or big businesses for managing the on-line currency world such as bitcoin etc.
• It is used in scientific lookup areas for inspecting statistics acquired from exploring the solar system, satellites, etc.

Mainframe computer:

Mainframe computer systems are designed in such a way that it can aid lots or thousands of users at the equal time. It additionally supports multiple applications simultaneously. So, they can execute distinctive techniques simultaneously. All these facets make the mainframe laptop best for big businesses like banking, telecom sectors, etc., which manner a excessive quantity of information in general.

Characteristics of mainframe computers:

• It is also an highly-priced or luxurious computer.
• It has excessive storage potential and brilliant performance.
• It can method a massive quantity of data (like information worried in the banking sector) very quickly.
• It runs easily for a long time and has a lengthy life.

 Minicomputer:

Minicomputer is a medium dimension multiprocessing computer. In this type of computer, there are two or greater processors, and it helps 4 to 200 users at one time. Minicomputers are used in places like institutes or departments for distinct work like billing, accounting, stock administration etc. It is smaller than a mainframe pc however large in evaluation to the microcomputer.

Characteristics of minicomputer:

• Its weight is low.
• Because of its low weight, it is convenient to lift anywhere.
• less highly-priced than a mainframe computer.
• It is fast.

Workstation/ Microcomputer:

Workstation is designed for technical or scientific applications. It consists of a fast microprocessor, with a massive quantity of RAM and excessive speed photo adapter. It is a single-user computer. It typically used to perform a unique challenge with incredible accuracy.

Characteristics of Workstation:

• It is steeply-priced or excessive in cost.
• They are exclusively made for complex work purposes.
• It gives large storage capacity, with higher graphics, and a extra effective CPU when in contrast to a PC.
• It is additionally used to take care of animation, statistics analysis, CAD, audio and video creation, and editing.

 PC (Personal Computer):

It is also acknowledged as a microcomputer. It is basically a general-purpose laptop and designed for individual use. It consists of a microprocessor as a central processing unit(CPU), memory, input unit, and output unit. This form of laptop is appropriate for non-public work such as making an assignment, watching a movie, or at workplace for workplace work, etc. For example, Laptops and computer computers.

Characteristics of PC (Personal Computer):

• In this restricted quantity of software program can be used.
• It is smallest in size.
• It is designed for non-public use.
• It is easy to use.

Analog Computer:

It is in particular designed to method analog data. Continuous facts that modifications continually and cannot have discrete values is called analog data. So, an analog laptop is used the place we don’t want genuine values or want approximate values such as speed, temperature, pressure etc. It can without delay take delivery of the data from the measuring system besides first converting it into numbers and codes. It measures the non-stop adjustments in bodily quantity. It gives output as a analyzing on a dial or scale. For example speedometer, mercury thermometer, etc.

 Digital Computer:

Digital computers are designed in such a way that it can without difficulty perform calculations and logical operations at excessive speed. It takes raw statistics as an enter and processes it with packages saved in its memory to produce the remaining output. It solely knows the binary enter zero and 1, so the uncooked enter records is transformed to zero and 1 by the pc and then it is processed with the aid of the pc to produce the result or remaining output. All cutting-edge computers, like laptops, desktops consisting of smartphones are digital computers.

Hybrid Computer:

As the name suggests hybrid, which capacity made via combining two exclusive things. Similarly, the hybrid computer is a aggregate of both analog and digital computers. Hybrid computer systems are quickly like an analog pc and have memory, and accuracy like a digital computer. So, it has the potential to manner each non-stop and discrete data. For working when it accepts analog alerts as input then it converts them into digital form earlier than processing the enter data. So, it is extensively used in specialized functions the place each analog and digital data is required to be processed. A processor which is used in petrol pumps that converts the measurements of fuel waft into volume and rate is an example of a hybrid computer.
