Various Storages

Storages are integral parts of computers. They enable computers to carry information over time as transmission devices carry information over space. In normal cases, a computer system includes several types of storages for different purposes.

CPU Registers

are used as workspace for computation.

Main Memory

is usually volatile but randomly accessible.

Hard Disks

provide computers with persistence and capacity.

Backup Devices

are slow and sequential but have huge capacity.

Caches

bridge the performance and cost gaps between devices.

Networks

are not storage devices but enable distributed storages.
