(i). Its operation is wholly electronic, and therefore, very fast, accurate and reliable.
(ii). Data must be transferred to the Main storage before it can be acted on by the Processor.
(iii). It provides direct data access, i.e., data is instantly accessible from the Main memory & the Processor can act directly on the data.
(iv). It is of low/ limited storage capacity.
The Internal memory of the computer is designed in such a way that it reaches a capacity beyond which it cannot extend.
(v). It is volatile.
For example, the RAM (the section of the Main memory that stores the user programs, application data, instructions and intermediate results during processing) loses its contents immediately when the power is switched off.
The Main memory is therefore, used to store temporary programs and data.
(vi). The speed of the processor depends on the Main memory.
(vii). It is very expensive, due to the technology involved & the elements used in making them.
