RAM - RANDOM ACCESS MEMORY

Memory types:

RAM, ROM and Cache Memory

RAM- Random Access Memory – it is dynamic memory and made by using capacitors and transistors, Slow compared to Cache memory.

Its contents are deleted after you reboot.

ROM –Read Only Memory – No changes possible after storage. Program is written once.

Cache Memory –

Cache Memory Static Memory [ made by using transistors] – It is the fastest and used to run your system faster. More cache memory = Fast computer.

DRAM- Dynamic RAM - [made by using transistors and capacitors] - Capacitor in this memory get discharge so it require refresh signal. So it is slow.

But it is cheaper than cache Static memory.

Types of cache memory – L1, L2 and L3 cache

L1 cache - inside CPU

L2 cache - on the CPU

L3 cache - on the motherboard

To check cache memory in the system . Open Task Manager→click

Performance tab → click on CPU
