MEMORY & STORAGE
DEVICES
Memory is an important component of a computer where all the data and
information are
stored in the form of binary digits (combination of 0‟s and 1‟s) and retrieved
whenever
necessary.
There are two main functions of the memory:
To store programs, data and
information into the computer.
To store the results of computation.
The storage devices of a computer system are ranked according to the
following criteria:
1. Access time: This is the time required to locate and retrieve
stored data from the
storage unit in response to a program instruction. That is the time interval
between
the read/write request and the availability of the data. A fast access time is
always
preferred.
2 . Storage capacity: It is the amount of data that can be
stored in the storage unit. A Memory System
