Speed : - A computer is a very fast device it can perform in few seconds, the amount of work that a human being can do in an entire year. Accuracy : - computers are very accurate. Accuracy of a computer is consistently high and the degree of its accuracy depends upon its design. Diligence : - A computer is free from monotony, tiredness and lake of concentration, unlike human Beings A computer will perform the last one with exactly the same accuracy and speed as the first one. Versatility : - Versatility is one of the most wonderful things about a computer. We can use computer to perform completely different types of work at the same time. Storage : - Computer can store mass storage of data with appropriate format. As Disadvantage No. I.Q :- A computer is a machine that has no intelligence to perform any

  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.
