Define flash memory, cache memory and virtual memory.
Flash
memory: Flash memory is a non-volatile memory chip used for storage and for
transferring data between a personal computer (PC) and digital devices.
It has the ability to be electronically
reprogrammed and erased. It is often found in USB flash drives, MP3 players,
digital cameras and solid-state drives.
Cache memory: Cache memory is a small sized type
of volatile computer memory that provides high speed data access to a processor
and stores frequently used computer programs, applications and data.
Virtual memory: Virtual memory is a memory
management capability of an OS that uses hardware and software to allow a
computer to compensate for physical memory shortages by temporarily
transferring data from random access memory (RAM) to disk storage.
OR
Virtual memory (VM) is a feature developed for
the kernel of an operating system (OS) that simulates additional main memory
such as RAM (Random Access Memory) or disk storage.
Certainly! Flash memory is non-volatile storage used in devices like USB drives. Cache memory is fast, volatile memory found in CPUs, enhancing data access speed. Virtual memory is a storage technique that uses a portion of the hard drive as RAM to manage resource allocation efficiently. Cache memory modules accelerate data retrieval.
