Limitations of Computer

A computer is a machine that can perform only within the limits set by the program. There can be two types of limits to computer operations, namely

i. Internal 

ii. External

1. Internal :

Computer has no intuition and ability to adapt. It cannot learn from past experience nor can it think, reason or discover. It cannot take decisions on its own. If incorrect information is fed into the computer, it will give incorrect result. A computer has no capability to anticipate nor can it act beyond instructions given to it. If there is a slight variation in the instruction given contrary to the intented one, it can not correct and it would only obey the incorrect instructions. In this case a human being can detect the error and suggest corrective action.

2. External :

In addition to a faulty program or wrong input data there could be errors due to power failures and voltage problem. The computer systems are also open to corruption due to viruses. Virus is a software program that affects the integrity of the operating system and/or data files. A virus may be introduced intentionally or by use of infected discs. Viruses are usually capable of reproducing themselves and can spread rapidly throughout the computer system. Another limitation with a computer system could be the absence of suitable security measures. Installing a computer system is quite expensive and moreover time consuming. Since the hardware technology is rapidly advancing, a computer may be technologically obsolete before it is installed.
