SSD (solid state drive)

RAM (Random access memory)

Cache

Flash Memory

Virtual Memory

ROM (Read Only Memory)

Registers

Solid storage media with no moving parts or a device that uses flash memory.

RAM is non volatile as it erases data when turned off and it holds data and information currently used by the CPU.

Cache is a hardware or software component that stores data to make the CPU execute instructions and data faster.

A kind of memory that stores data without a use of power.

Virtual memory is simulated memory that is written to a file on a hard drive that appears to exist as RAM but is secondary storage

ROM is volatile and is not erased. It is permanently on the ROM chip and holds the start up system and the bootstrap loader.

MAR (Memory address register) copies and transfers the data on the PC (program counter) through the address bus.

PC (Program counter) is where the next instruction is held in the processor.

MDR/MBR (Memory Data/Buffer Register) is where data and instructions are held to be executed.

CIR (Current Information Register) is where the information from the MDR is held after it has been executed.
