Computer in all its form

From time to time, science has provided us with different surprises one of which is today’s computer. Few years back, Computer had never been the way we see it today. Today computer are present in different sizes and patterns.

Presently computer is of four types depending on the size:

1. Supercomputer: A super computer is a computer that performs at very high operational rates. It is basically used for engineering and scientific works that require very large database. At present there are just a handful amount of supercomputers in the whole world among which Sunway TaihuLight of Wixu, China is the fastest.

2. Mainframe computers: Mainframe computer is almost similar to Super computer in function since its also used for heavy duty works like mission critical operations requiring high volumes of data processing. Its also large in size but yet neither as big as supercomputer nor as fast as it. IBM zSeries,  IBM z13, System z9 and System z10 servers are some examples.

3. Mini Computers: It refers to small computers that intermediate between mainframe computer and microcomputer in size, speed, and capacity, that can support time-sharing, and is often dedicated to single application Control Data's CDC 160A and CDC 1700, DEC PDP and VAX series, Hewlett-Packard, HP 3000 series and HP 2100 series are  some mention able examples of Mini computers.

4. Micro computers: The computers we basically use from day to day life like the Desktop, laptops, tablets are categorized in Micro computer. Some micro computers:

A. Desktop: Regular computers that used usually and are easy to fit in on desks or corners.

B. Notebook or laptop: Portable and lightweight computers that easily fit into briefcases as well.
