compatible peripheral.
Port, number
– Used to identify a specific process to which an Internet or other network message is to be forwarded when it
arrives at a server.
Port, software – A memory address that identifies the physical circuit used to transfer information between a microprocessor
and a peripheral.
Protocol
– In IT terminology, this describes the special set of rules that end points in a telecommunication connection use
when they communicate.
RAM (Random Access Memory)
– Generally referred to as a computer’s “memory.” An integrated circuit memory chip that
allows information to be stored and retrieved by a microprocessor or controller. The information can be stored or accessed
in any order, and all storage locations are equally accessible.
Seek Time
– The amount of time (in thousandths of a second, or milliseconds) that it takes a hard drive’s read/write head
to move to a specific location on the disk. Average seek, then, is the average of a large number of random samplings all
over the disk. Seek time is CPU independent, meaning that seek time is the same for a disk drive, whether it is attached to a
computer or not.
Software
– In a nutshell, software is a set of instructions for the computer. A set of instructions to perform a particular
task is called a program. There are two main types of software: system software (an operating system such as Mac OS or
Windows) which controls the operation of the computer and application software (programs such as Word or Excel) which
enable users to perform tasks such as word processing, spreadsheet creation, graphics, etc.
Storage
– In computers, any equipment in which information may be kept. PCs generally use disk units and other external
storage media (diskettes, CD-ROMs, magnetic disks, etc.) for permanent storage of information.
Striping
– Spreading data evenly over multiple disk drives to enhance performance. Data striping can be performed on a
bit, byte or block basis for optimum application performance.
Subnetwork (Subnet)
– This is a separate, identifiable part of a network, such as all of the computers at one geographic
location, in one building or on the same local area network. Subnets make it possible to have an organization’s network
connected to the Internet with a single, shared network address.
Transfer Rate
– The rate at which the drive sends and receives data from the controller. Transfer rates for reading data from
the disk drive may not be the same as the transfer rate for writing data to the disk drive. Transfer rates are CPU dependent,
