Detailed explanation-1: -Secondary storage is named as such because it doesn’t have direct access to the CPU. As a result, it is considerably slower than primary storage.
Detailed explanation-2: -Primary memory is volatile, while secondary memory is non-volatile. Primary memory is stored on semiconductor chips, while secondary memory is stored on external hardware devices. Primary memory is classified into cache and random access memory, while secondary memory has no such categories. Primary memory is faster.
Detailed explanation-3: -All devices/computers capable of storing high-volume data are secondary memory. These types of memories are slower than primary memory. However, it can save a large amount of data, from gigabytes(GB) to terabytes(TB). Backup storage or mass storage media are the other names for Secondary memory.
Detailed explanation-4: -Hence the correct order of the computer storage devices in order of speed of data retrieval from fastest to slowest is as follows: main memory, hard disk, and CD-ROM.
