Characteristics of Computer

Speed - Computer can process millions of instructions per second.

Accuracy - Computer performs any given task with 100% accuracy rate.

Diligence - Millions of jobs or calculations can be completed by a computer with the same consistency and accuracy. It doesn't sense any fatigue or loss of attention. It is also superior to humans in terms of memory.

Reliability - Computer has higher reliability because it has high accuracy and speed.

Versatility - The ability of a computer to carry out many tasks with the same level of accuracy and effectiveness is referred to as versatility.

Storage - Computers have high storage capability, even if the primary memory is full we can use secondary storage and we can also use external storage devices.
