Study Notes

Primary Storage

Primary storage is directly accessible to the CPU.
Main memory or immediate access store (IMAS)
Located on the motherboard
Consists of RAM and ROM chips.
RAM is volatile which means data is lost when the computer is turned off.
RAM is temporary and used for active processing.
RAM is expensive and has a limited capacity.
ROM is nonvolatile which means data is retained when the computer is turned off.
ROM stores the BIOS program and other system level programs.
ROM is used for starting the computer.

Secondary Storage

Also called auxiliary or backup storage.
Permanent storage compared to RAM.
Cheaper than primary storage.
Unlimited capacity compared to primary storage.
Examples include magnetic disks, optical disks, flash memory, and USB drives.
