IP
Internet Protocol. IP is a layer 3 network protocol that
is the standard for sending data through a network. IP
is part of the TCP/IP set of protocols that describe the
routing of packets to addressed devices. An IP address
consists of 32 bits divided into two or three fields: a
network number and a host number or a network
number, a subnet number, and a host number.

IP Address

Internet Protocol Address. A unique identifier for a
device attached to a network using TCP/IP. The address
is written as four octets separated with periods
(full-stops), and is made up of a network section, an
optional subnet section and a host section.
ISP
Internet Service Provider. An ISP is a business that
provides connectivity to the Internet for individuals and
other businesses or organizations.
LAN
Local Area Network. A network of end stations (such
as PCs, printers, servers) and network devices (hubs and
switches) that cover a relatively small geographic area
(usually not larger than a floor or building). LANs are
characterized by high transmission speeds over short
distances (up to 1000 metres).
Layer 2
Data Link layer in the ISO 7-Layer Data Communications
Protocol. This is related directly to the hardware
interface for the network devices and passes on traffic
based on MAC addresses.
Link Aggregation
See Trunking.
MAC
Media Access Control. A protocol specified by the IEEE
for determining which devices have access to a network
at any one time.
MAC Address
Media Access Control Address. Also called the
hardware, physical or Ethernet address. A layer 2
address associated with a particular network device.
Most devices that connect to a LAN have a MAC
address assigned to them as they are used to identify
other devices in a network. MAC addresses are 6 bytes
long.
