     Super Computer Supercomputers are the fastest computer and have a large data storage capacity. A supercomputer can execute more than 100 million instruction per second. It has multiple processors which are based on parallel processing architecture for achieving high speed. It is made for some special purpose. It can support more than 1000 users at a time. It is used for Space Research, satellite management, Wheatear forecasting Aerodynamics, and complex computation. Ø First Indian Super Computer “PARAM2000”. Ø The first supercomputer is CDC 6600 (designed by CDC Control Data Corporation in USA). Ø The first five fastest supercomputer of the world are 1.       Summit (US) 2.     Sierra (US) ... 3.     Sunway TaihuLight (China) ... 4.     Tianhe-2 (China) ... 5.      Frontera (US) Ø Speed of Supercomputer is measured in FLOPS. Ø FLOPS (Floating Point Operation per Second). MAINFRAME COMPUTER A mainframe is a very large in size computer which is capab

  The word “computer” comes from the word “compute”, which means to calculate”. Charles Babbage is known as the ' Father of computer' .  A computer often referred to as a “data processor” because it can store, process, and retrieve data whenever desired.  The activity of processing data using a computer is called data processing.    Data processing consists of three sub activities:- (1)          Capturing input data (2)          Manipulating the data and (3)          Managing output results. Data : - Data is raw material used as input to data processing. Data can be anything like numerical, non-numerical or a mixture of both. Information : - Information is processed data obtained as output of data processing. Computer: - A computer is an electronic device which performs numerical calculation and logical calculation at high speed and produces information that are expressible in numerical as well as in logical form.
