IP address Acronym for `Internet Protocol' address. IP is the protocol within
TCP/IP that is used to send data between computers over the Internet. An IP ad-
dress is an assigned number used to identify a computer that is connected to a
network through TCP/IP. An IP address consists of four numbers (each of which
can be no greater than 255) separated by periods, such as 192.168.1.1.
IP Acronym for `Internet Protocol'. The protocol within TCP/IP that is
used to send data between computers over the Internet. More specifically, this pro-
tocol governs the routing of data messages, which are transmitted in smaller com-
ponents called packets.
ISO/OSI reference model Abbreviation for "International Organization for Stand-
ardization Open Systems Interconnection" reference model. An architecture that
standardizes levels of service and types of interaction for computers that exchange
information through a communications network. The ISO/OSI reference model
separates computer-to-computer communications into seven protocol layers, or
levels; each builds on and relies on the standards contained in the levels below it.
The lowest of the seven layers deals solely with hardware links; the highest deals
with software interactions at the program level. It is a fundamental blueprint de-
signed to help guide the creation of hardware and software for networks.
ISP Acronym for `Internet service provider'. A company that provides individuals
or companies access to the Internet.
Kbps Abbreviation of `kilobits per second'. Data transfer speed, as through
a modem or on a network, measured in multiples of 1,000 bits per second.
LAN Acronym for `local area network'. A group of computers and other de-
vices dispersed over a relatively limited area (for example, a building) and connect-
ed by a communications link that enables any device to interact with any other on
the network.
MAC address Abbreviation for `media access control' address. The address
that is used for communication between network adapters on the same subnet.
Each network adapter is manufactured with its own unique MAC address.
MAC layer Abbreviation for `media access control' layer. The lower of two sub
layers that make up the data-link layer in the ISO/OSI reference model. The MAC
layer manages access to the physical network, so a protocol like Ethernet works at
this layer.
Mbps Abbreviation of `megabits per second'. A unit of bandwidth measure-
ment that defines the speed at which information can be transferred through a net-
work or Ethernet cable. One megabyte is roughly equivalent to eight megabits.
Modem A device that transmits and receives information between computers.
MPPE Microsoft Point to Point Encryption (MPPE) is a means of represent-
ing Point to Point Protocol (PPP) packets in an encrypted form.
Multicast To transmit a single message to a select group of recipients. A simple
example of multicasting is sending an e-mail message to a mailing list. Teleconfer-
encing and videoconferencing also use multicasting, but require more robust proto-
cols and networks.
