Q6) Answer the following questions :-
a) Solution:
Computer memory is a part or storage place where the data or instructions which
are feeded into computer are being stored. There are different types of computer memories but mainly two memories are used viz are i) Primary memory and ii) Secondary memory. The user can also access the data or instructions stored in the computer memory whenever it’s required but if it’s stored then only. Storing of data/instructions on the computer memory reduces the work feeding of data or instructions again and again in the computer system. Storage capacity of computer memory is measured in bytes, kilobytes(kb), Mega bytes (Mb) giga bytes (gb) etc.
b) Solution:
c) Solution:
d) Solution:
i) ROM :- ROM stands for Read Only Memory. The data or instructions stored on
such type of memory, does not gets erased even if the power supply is been turned off. It holds the data for a long period of time. RAM memory is permanent memory. The data which is written on ROM, cannot be changed/ altered. It can be only read.
ii) PROM:- It stands for Programmable Read Only Memory. They are manufactured as blank chips, which are used to write any data with the help of PROM programmer.
e) Solution:
Cache is the special small and high speed storage/memory within the central
processing unit of the computer system for frequent access. It deals with the increase in the processors speed. When the processor performs the task of read and write operations it first checks cache memory.
