Classification of Computers

Types of Computer/Classification of Computers

• Supercomputer
• Mainframe Computer
• Microcomputer
• Minicomputer

1.Supercomputer:

A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).

• Powerful. Funnels capacity into a few programs as quickly as possible. ...
• Expensive. Hundreds of millions of dollars. ...
• Built for specific applications. Animating graphics. ...
• Made up of tens of thousands of computing nodes. CPUs. ...
• Most controlled by Linux software. ...
• Water cooled.

At any given time, there are a few well-publicized supercomputers that operate at extremely high speeds relative to all other computers. The term is also sometimes applied to far slower (but still impressively fast) computers. The largest, most powerful supercomputers are really multiple computers that perform parallel processing. In general, there are two parallel processing approaches: symmetric multiprocessing (SMP) and massively parallel processing (MPP).

As of June 2016, the fastest supercomputer in the world was the Sunway TaihuLight, in the city of Wixu in China. A few statistics on TaihuLight:

• 40,960 64-bit, RISC processors with 260 cores each.
• Peak performance of 125 petaflops (quadrillion floating point operations per second).
• 32GB DDR3 memory per compute node,  1.3 PB memory in total.
• Linux-based Sunway Raise operating system (OS).

2. Mainframe Computer:

Mainframes (also called "big iron") are powerful computers used for large information processing jobs. They are mainly used by government institutions and large companies for tasks such as census, industry and consumer statistics, enterprise resource planning, and financial transaction processing.

*How does a mainframe computer work?

A mainframe computer is a combination of memory (RAM) and many processors. It acts as a central processing unit for many workstations and terminals connected with it. A mainframe computer is used to process the large and huge amount of data in petabytes. It can control thousands of user 's.

*Who made mainframe computer?

The UNIVAC I (UNIVersal Automatic Computer I) was the first commercial mainframe computer produced in the United States, in March , 1951. It was designed principally by J. Presper Eckert and John Mauchly, the inventors of the ENIAC, the first general purpose electronic digital computer, operational in 1946.

*What is the purpose of mainframe computer?

Mainframe computers or mainframes (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing.

*What is the role of mainframe developer?

Mainframe Developer Responsibilities and Duties. ... Head responsibility to integrate system on allocated software projects and perform as project manager or technical lead for those projects. Analyze designs, develop and execute custom application features and functions.

3.Microcomputer:

The definition of a small personal computer with a microprocessor as a central processor is an example of a microcomputer. A tiny little handheld computer device similar to a SmartPhone that has a central microprocessor is an example of a microcomputer.

*What is microcomputer explain?

A microcomputer is a computer with a central processing unit (CPU) as a microprocessor. Designed for individual use, a microcomputer is smaller than a mainframe or a minicomputer. The term microcomputer is not as commonly used as it was during the 1970s-1980s
