RAM is slower than secondary storage

RAM is non-volatile

when software, applications and data are opened they are copied from secondary storage to RAM

When a computer turns on, the OS automatically loads

Main memory is where files, data and programs are being stored - even when switched off

Computers have unlimited amount of RAM storage

when RAM runs out, virtual memory is used

virtual memory is where uncommonly used programs etc are stored

virtual memory is needed when the computer switches off

The CPU can easily read memory in virtual memory

using virtual memory makes computers slow when switching between apps or using a memory-intensive application.

ROM is volatile memory

ROM is found on a flash memory chip in the motherboard

the BIOS is not found on ROM, but instead on the OS

as soon as the computer is switched on, the CPU reads the ROM instructions

ROM can be written to, despite its name
