Computer Fundamentals,What is Computer, Computer is an advanced electronic device that takes raw data as input from the user and. processes these data under the control of set of instructions called program and gives. the result output and saves output for the future use It can process both numerical and. non numerical arithmetic and logical calculations,A computer has four functions. a accepts data Input,b processes data Processing,c produces output Output.
d stores results Storage,Input Data, Input is the raw information entered into a computer from the input devices It is the. collection of letters numbers images etc, Process is the operation of data as per given instruction It is totally internal process of. the computer system, Output is the processed data given by computer after data processing Output is also. called as Result We can save these results in the storage devices for the future use. Computer System, All of the components of a computer system can be summarized with the simple. COMPUTER SYSTEM HARDWARE SOFTWARE USER,Hardware Internal Devices Peripheral Devices.

On the basis of Size,a Super Computer, The fastest type of computer Supercomputers are very expensive and are employed for. specialized applications that require immense amounts of mathematical calculations For. example weather forecasting requires a supercomputer Other uses of supercomputers. include animated graphics fluid dynamic calculations nuclear energy research and. petroleum exploration, The chief difference between a supercomputer and a mainframe is that a supercomputer. channels all its power into executing a few programs as fast as possible whereas a. mainframe uses its power to execute many programs concurrently. b Mainframe Computer, A very large and expensive computer capable of supporting hundreds or even. thousands of users simultaneously In the hierarchy that starts with a simple. microprocessor in watches for example at the bottom and moves to supercomputers at. the top mainframes are just below supercomputers In some ways mainframes are more. powerful than supercomputers because they support more simultaneous programs But. supercomputers can execute a single program faster than a mainframe. c Mini Computer, A midsized computer In size and power minicomputers lie between workstations and. mainframes In the past decade the distinction between large minicomputers and small. mainframes has blurred however as has the distinction between small minicomputers. and workstations But in general a minicomputer is a multiprocessing system capable of. supporting from 4 to about 200 users simultaneously.
