The word ‘Computer’ comes from the Greek word “compute” which means to calculate. In fact, the original objective for inventing the computer was to create a fast calculating machine.
- However, more than 80% of the work done by computers today is of non-mathematical or non-numerical nature. Hence, to define a computer merely as a calculating device is to ignore over 80% of its functions.
A computer is a multitasking electronic device that is capable of performing a lot of tasks within a single moment.
- It can solve problems by accepting data and instructions, processing the data according to the given instructions and presenting the results of operation through a suitable output media.
