This type of storage provides only temporary or volatile storage.
RAM
Compact drive, also known as a flash drive, which is used to transport data and information between computers, specialty devices and the Internet.
USB drive
Measures the amount of time required by the storage device to retrieve data and programs.
access speed
A characteristic of secondary storage that measures how much a particular storage medium can hold.
capacity
When a read/write head makes contact with the hard disk's surface, it causes a head:
crash
Help with file organization; run through each track of a stack of platters.
cylinder
Measures how tightly the magnetic charges can be packed next to one another on the disk.
density
Improves hard disk performance by acting as a temporary high-speed holding area between a secondary storage device and the CPU.
disk caching
This hard-disk performance enhancement anticipates data needs.
disk caching
An organizational strategy to promote efficient and safe use of data across the networks.
enterprise storage system
Type of hard drives that are removable and typically connect to a USB or FireWire port on the system unit.
external
