Redundant Array of Inexpensive
Disks. A method of using two or more disks to constantly mirror
or store your data in such a way that if one disk fails, all is not
lost. There are different types of RAID, ranging from RAID1 (One disk mirrored
onto another) through to RAID5 (Information spread across a number of
disks, as pictured:)

| RAM |
Random Access Memory.
Volatile memory; memory that is lost when the computer is turned off.
RAM is based on semi-conductor circuitry and is accessed by other parts
of the computer. The amount of memory a computer has is measured in
megabytes (MBs) or gigabytes (GBs). The more RAM you have, generally the
faster you computer will run and more programs that can be ran at the
same time. RAM is usually removable and therefore usually can be
upgraded, although a number of technical restrictions may apply.
