• Speed:

A computer is a fast data processing system. The time taken by the computer system to execute any task is very fast. It can process thousands of millions of data within a second. A recent computer has a speed of 300 MHX. This means that it can execute an instruction in about 10 nanoseconds.

• Accuracy:

Although computer works at very high speed, it doesn’t make any mistake in data processing. It is 100% accurate machine. Errors can occur in a computer, but these errors are due to inaccurate data or bugs. That means if we feed the wrong data to a computer then the result produced by a computer is also wrong.
