Q6.Answer the following questions.

 

a.Define computer. Explain speed and accuracy characteristics of a computer.

A computer is a machine that can store, process, and retrieve information.

Speed means how fast a computer can work, and

accuracy means how correctly it can do tasks.

 

b.What do you mean by storage capacity of a computer? Write the different storage units of computer.

Storage capacity of a computer refers to how much data it can hold.

 

Different units for storage are

kilobyte (KB),

megabyte (MB),

gigabyte (GB), and

terabyte (TB).

 

c. Explain diligence of a computer in brief.

Diligence of a computer means it can do repetitive tasks without getting tired or making mistakes.

 

d.Why is computer called versatile machine?

A computer is called a versatile machine because it can do many different things like calculations, graphics, and communication.
