A computer is a device that accept information and manipulate it for some result based on a program or sequence of instruction how the data is to be processed Complex computer also include the means of storing data for some necessary duration a program maybe in variables and built into computer or different program may be provided to computer today's computer have both kind of programming
Features and characteristics of computer: high speed, accuracy, large storage capacity. high availability and versatility are some important features of computer
Speed: it has a very high speed of execute instruction CPU of a computer can perform more than 10 million operation per second all the instructions are executed
Storage :the speed with which computer can process large quantities of data information the size of inputs also the output is quite larger size of information to be stored for the increase due to Graphic application all these information is to be installed in auxiliary memory that is hard disc fitted inside the computer
Accuracy: the accuracy of result computer by computer is consistently high due to digital teknik the error is very small the error in computing may be due to logical mistake by a program or due to inaccurate data
Reliability: the reliability of result processed by a computer is very high for a program is executed any number of time with same set of data Abbott and the result would be the same
Verstality :computer are capable of performing all the tracks provided that as can be reduced to a series of logical steps so that appropriate program in a suitable language can be fed to a computer memory of course the input and output device should be capable of performing the desired task because of these capability is a number of process can automated with the help of computer
apart from those outline about computer and some other features also they are automatic to a great extent that is a run with very little human interference they can work and less at the same level of efficiency and productivity modern computer are becoming more and more user-friendly that is computers it self help the user at every stage visual display limited but effective use of natural language life English and appropriate software has been made it very easy to operate computer
