Magnetic tape is secondary storage device used for storing files of data; Example: a company’s payroll record
Access is sequential and consists of records that can be accessed one after another as the tape moves along a stationary read-write mechanism
A hard disk is an electromechanical data storage device from which data is accessed in a random-access manner, individual blocks of data can be stored or retrieved in any order
Both sequential and random access of data is possible in hard disk
In random-access memory (RAM) the memory cells can be accessed for information transfer from any desired random location
That is, the process of locating a word in memory is the same and requires an equal amount of time no matter where the cells are located physically in memory; Hence RAM is random access
