IP Address. The 32-bit numeric address that identifies a computer or device on a
TCP/IP network. An IP address is written as four numbers separated by periods.
For example, 1.160.10.240 could be an IP address.
IPX (internetwork packet exchange). A networking protocol used for
connectionless communications.
Kbps (kilobits per second). A measure of bandwidth capacity or transmission
speed representing a thousand bits per second.
Kilobit. 1,024 bits for technical purposes, such as data storage. 1,000 for general
purposes. Data transfer rates are measured in kilobits per second, abbreviated as
Kbps, and count a kilo as 1,000 bits.
Kilobytes. In decimal systems, kilo stands for 1,000, but in binary systems, a kilo
is 1,024 (2 to the 10th power). Technically, therefore, a kilobyte is 1,024 bytes,
but it is often used loosely as a synonym for 1,000 bytes. In computer literature,
kilobyte is usually abbreviated as K or KB. To distinguish between a decimal K
(1,000) and a binary K (1,024), the IEEE has suggested following the convention
of using a small k for a decimal kilo and a capital K for a binary kilo, but this
convention is by no means strictly followed.
LAN (local area network). A data communications network covering a small
area, usually within the confines of a building or floors within a building.
Common LAN protocols are Ethernet and Token Ring.
LED (light-emitting diode). An electronic device that lights up when electricity
is passed through it.
Line sharing. Allows a consumer to use his or her existing phone line for both
normal phone service provided by the local phone company and high-speed
digital subscriber line (DSL) Internet access through another provider.
MAC (media access control) Address. A unique hardware address that identifies
each node of a network.
Mbps (megabits per second). A measure of bandwidth capacity or transmission
speed. It represents a million bits per second.
MBps (megabytes per second). A measure of bandwidth capacity or
transmission speed. It represents a million bytes per second.
Megabit. When used to describe data storage, 1,024 kilobits. When used to
describe data transfer rates, it refers to one million bits. Network speeds are often
measured in megabits per second.
Megabyte. When used to describe data storage, 1,048,576 bytes. Megabyte is
frequently abbreviated as M or MB. When used to describe data transfer rates, as
in MBps, it refers to one million bytes.
Microsoft Windows®. A computer operating system by Microsoft Corporation,
Modem (MOdulator/DEModulator). Equipment that converts digital signals to
analog signals and vice versa. Modems are used to send data signals (digital) over
the telephone network, which is usually analog.
