Answer

Computer is an automatic machine: Once the data and instructions are fed into a computer, it executes them one by one without human intervention.
Memory or Storage: The memory of a Computer is so large that it can store any volume of information or data for being processed. Such informations can be stored in it on a permanent basis on magnetic discs, floppy discs, punched cards or microfilms etc. The information stored in it can also be recalled at any time when required.
High Speed: Computers are known for their lightning speed of operations. The speed is so high that it is ordinarily expressed in microseconds (1 micro second $=\frac{ 1}{10,00,000}$ of one second). In other words, they can perform millions of operations in one second. Moreover, the calculations will be error-free and the speed is rapidly increasing day-by-day.
