Memory: RAM, ROM and Cache
RAM (Random Access Memory)
RAM is the main memory of a computer.
It is a volatile memory, meaning its contents are lost when the computer is powered off.
RAM is responsible for loading and executing instructions from hard disk or other storage devices into the processor.
It has much faster access times compared to ROM and cache.
ROM (Read-Only Memory)
ROM is a non-volatile memory.
It is permanently programmed into the chip during manufacturing.
ROM contains firmware, operating system, and other essential software that cannot be changed during normal operation.
It is used for critical system tasks, such as booting the computer and managing hardware controls.
Cache Memory
The cache is a memory that is faster than RAM but slower than ROM.
It is used as an intermediate storage between RAM and the CPU.
The cache is divided into two parts: a data cache and a instruction cache.
The data cache stores recently used data, while the instruction cache stores frequently used instructions.
The cache is updated by the CPU frequently, but it is much faster than RAM
