4. Data and Information Storage
The fourth and equally very important function of a computer
is data and information storage. After sleepless nights of video and
animation creation and editing, the user wants to have the finished
product stored for future dissemination and additional editing.
A computer can store information internally and externally.
The hard disk drive (HDD) and/or solid-state disk drive (SSD) are
internal storage devices and serve to protect and house all data and
information on a computer. In bigger systems, the RAID system is
used. Multiple disk drives operate simultaneously to ensure data
and information integrity.
External storage is achieved through accessories that attach
externally to the computer. They include external drives and opti-
cal disks.
