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.
