Partition — A logical division on a hard drive that the operating system treats as a
separate hard drive. Each partition is assigned a unique drive letter.
Port (Hardware) — A specialized outlet on a device for connecting to other devices
using a cable or a plug. Ethernet ports, power ports, and USB ports are examples.
Protocol — A convention of data transmission that defines timing, control format,
and data representation.
RAID — Redundant Array of Independent Disks. A grouping of hard drives in a single
system to provide greater performance and data integrity.
RAID 0 — RAID protocol in which data is striped across multiple hard drives,
enabling the accelerated reading and recording of data by combining the work of two
or more drives to increase performance. See also Striping.
RAID 1 — RAID protocol in which two copies of the data are instantaneously
recorded — each on separate hard drives. RAID 1 ensures the protection of users'
data because in the event that one of the hard drives fails, the other hard drive(s)
continue to read and write data until the faulty hard drive is replaced and rebuilt to
once again safely mirror the data. See also Mirroring.
RAM — Random Access Memory. Memory that allows any storage location to be
accessed randomly, as opposed to sequential access devices such as tape drives.

Spanned — Combines drives in a linear fashion to create one large logical volume. A
spanned drive is like a single, bigger drive, in that files written to the volume earlier go
to the “beginning” of the volume, on the first physical drive. If one of the drives fails, all
data is lost.
SSH — Secure Shell. A network protocol that uses encryption and authentication
keys to enable two devices on the network to exchange data securely. See also

services between a web server and a web browser. See also Protocol.
