Explanation
The term ‘Computer’ is derived from a Latin word “computare” which means to “to calculate”, “to count”, “to sum up” or “to think together”. So, more precisely the word computer means a “device that performs computation“.

Explanation
an Assistant sub-inspector (ASI) is a non-gazetted police officer ranking above a police head constable and below a Sub-inspector.

Explanation
Read-only memory is a type of non-volatile memory used in computers and other  electronic devices. Data stored in  ROM  cannot be electronically modified after the manufacture of the memory device.

Explanation
A media access control is a network data transfer policy that determines how data is transmitted between two computer terminals through a network cable.

Explanation
RAM and ROM difference       Sr# RAM ROM 1.                       Ram stands for  Random Access Memory ROM stands for  read-only memory , 2.                       Ram operation is  read and write Ram operation is  only read 3.                       It is like something  written on sand  which is temporary and would be erased. It is like something  written on stone  that cannot be removed or changed once written. 4.                       It is  temporary memory , also called volatile memory. It is  permanent storage  devise and data remains safe on ROM even when  computer is off  also called non-volatile memory. 5.                       RAM  stores information which is currently processed by computer.  When power off, it loses all the information. Data can be read, stored, modified or delete from the RAM. It contains information related to  computer startup  process which is written at the time of memory manufacturing 6.                       volatile memory non-volatile memory 7.                       It is a  high-speed  memory.
