Define ‘Diligence’ in the context of computers.
A computer can perform millions of tasks or calculations with the same consistency and accuracy without fatigue.
What does ‘Versatility’ refer to in computing?
The capability of a computer to perform different kinds of work with the same accuracy and efficiency.
How do computers achieve high ‘Speed’?
By processing millions of instructions per second, measured in microseconds and nanoseconds.
What is meant by ‘Accuracy’ in computers?
Computers perform calculations with 100% accuracy, with potential errors due to data inconsistency.
