Solution:
Storage Devices:
1. Definition: Storage devices are the hardware components used to store, retrieve, and transfer digital data.
2. Examples: Hard disk drives (HDD), solid-state drives (SSD), USB flash drives, memory cards, optical drives (CD/DVD/Blu-ray), magnetic tape drives.
3. Function: Storage devices provide non-volatile storage (data is retained even when power is turned off), allowing users to save and access data in the long term.
4. Capacity: Storage devices come in different storage capacities, ranging from a few gigabytes (GB) to several terabytes (TB) or even petabytes (PB).
5. Portability: Some storage devices like USB flash drives and memory cards are portable and can be easily carried and connected to various devices.
Storage Media:
1. Definition: Storage media refers to the physical material or medium on which data is stored, such as disks, tapes, or chips.
2. Examples: Hard disk platters, magnetic tape, CD/DVD/Blu-ray discs, semiconductor chips.
3. Function: Storage media act as the platform where the actual data is written, encoded, and stored.
4. Types: Storage media can be classified into magnetic media (e.g. hard disks, magnetic tapes), optical media (e.g. CDs, DVDs, Blu-ray), and solid-state media (e.g. semiconductor chips, SSDs).
5. Read/Write: Storage media can be read-only (such as CDs or DVDs) or read-write (such as hard disks or SSDs), determining whether data can only be retrieved or modified as well.
