FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Secondary storage devices are generally separated into three types: magnetic storage devices, such as hard disk drives and tapes. optical storage devices, such as CDs, DVDs and Blu-ray discs. solid state storage devices, such as solid state drives (SSDs) and USB memory sticks.

Detailed explanation-2: -There are three main categories of storage devices: optical, magnetic and semiconductor. The earliest of these was the magnetic device. Computer systems began with magnetic storage in the form of tapes (yes, just like a cassette or video tape).

Detailed explanation-3: -There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive.

Detailed explanation-4: -Most of today’s optical disks are available in three formats: compact disks (CDs), digital versatile disks (DVDs)–also referred to as digital video disks–and Blu-ray disks, which provide the highest capacities and data transfer rates of the three.

Detailed explanation-5: -Storage devices are available in different forms, depending on the type of underlying device. For example, a standard computer has multiple storage devices including RAM, a cache, and a hard disk. The same device may also have optical disk drives and externally connected USB drives.
