Questions with Long answers.
Question:1 Write a note on
primary memory?
Answer: Primary memory is also
called internal memory or main memory. This memory is part of the CPU. Primary
memory stores only those data and instructions on which the computer is working
at that time. Micro conductors are used in it which are very fast and special
types of electronic circuits. The larger the size of the main memory of the
computer, the faster that computer is considered.
Question:2 What is a hard disk
drive (HDD)? Explain in detail.
Answer: Internal hard disk is
also called fixed disk, it is a permanent type of memory, it works at a lower
speed than primary memory. The CPU does not use the data stored in it directly,
the data stored in the hard disk is first sent to the main memory and then the
CPU uses it. It is made of one or more strong metal plates, on which a layer of
metal oxide is coated. Data is recorded magnetically in the hard disk. Data is
stored in all the disks except the bottom and top disks of the internal hard
disk. A read-write head is installed on each disk. The platters installed in
the hard disk rotate the disk at a high speed, the disk rotates at a speed of
5400 to 7200 revolutions/minute. The storage capacity of a typical computer can
be from 20 GB to 1 TB.
Question: 3 What is secondary
memory? Tell about any one secondary memory device.
Answer: Secondary memory is also
called external memory, auxiliary memory or physical memory. Data and
information can be stored in secondary memory for a long time. The information
in it is not erased when the power goes out. Its capacity to read and write
data is higher than that of the main memory. Its cost is also very low.
Secondary memory is used as auxiliary memory because of its ability to store
more information.
