SECONDARY STORAGE :

Secondary storage is a term that applies to a wide range of devices that provide persistent (permanent) storage for data files and applications. Secondary storage is non-volatile, so does not require a power supply. You have already learnt that main memory is needed to store data and instructions during processing

The UNIVAC I (1951) used seven memory units, each containing 18 columns of mercury, storing 120 bits each. This provided a memory of 1000 12-character words with an average access time of 300 microseconds.
