The limitations of computer systems are as follows – Lack of in-built intelligence – Computer is a simple device that works as per the instructions fed in it. It comes with zero IQ, which prevents it from making any decisions to generate better outputs. Lack of decision-making capabilities – Decision-making is a complex process that includes analysis of data using knowledge, intelligence, and wisdom. A computer system lacks the ability to make wise decisions on its own. They are only programmed to take a specific set of decisions and work accordingly.
