Detailed explanation-1: -A Register is commonly used to accept, store, and transfer data and instructions as fast as possible. The process done by the Register is then used by the CPU(Central Processing Unit). The Register is also said to be the High-speed Memory Storing Unit.
Detailed explanation-2: -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.
Detailed explanation-3: -The devices are easily available online and offline and need no expertise for usage. The capacity and size of these drives and devices has become an added advantage. Even in terms of performance, using these storage devices the data can be saved easily but can also be transferred easily from one device to another.
Detailed explanation-4: -While hard disks have moving parts, solid state drives are shock-resistant. If you drop your laptop while the read/write head of a hard drive is in motion-which it usually is-it could result in data failure. This doesn’t happen with SSDs.
