TERMINOLOGY
10BaseT
10BaseT is a physical Layer Specification for Twisted-Pair Ethernet using
Unshielded Twisted Pair wire at 10Mbps. This is the most popular type of LAN
cable used today because it is very cheap and
easy to install. It uses RJ-45
connectors and has a cable length span of up to 100 meters. There are two
versions, STP (Shielded Twisted Pair) which is more expensive and UTP
(Unshielded
Twisted Pair), the most popular cable. These cables come in 5
different categories. However, only 3 are normally used in LANs, Category 3,
4 and 5. CAT 3 TP (Twisted Pair) cable has a network data transfer rate of up
to 10Mbps. CAT 4 TP cable has a network data transfer rate of up to 16Mbps.
CAT 5 TP cable
has a network data transfer rate of up to 100Mbps.
Access Point
Access Point is a
device that is able to receive wireless signals and transmit
them to the wired network, and vice versa, thereby creating a connection
between the wireless and wired networks.
Ad-Hoc
An Ad-Hoc wireless LAN is a group of computers, each with LAN adapters,
connected as an independent wireless LAN.
Adapter
An adapter is a device used to connect end-user nodes to the network;
each one
contains an interface to a specific type of computer or system bus, e.g. EISA,
ISA, PCI, PCMCIA, CardBus, etc.
Auto-negotiation
Auto-negotiation is a
signaling method that allows each node to define its
operational mode (e.g., 10/100 Mbps and half/full
duplex) and to detect the
operational mode of the adjacent node.
Backbone
Backbone is the core infrastructure of a network. The portion of the network
that transports information from one central location to another central location
where it is unloaded onto a local system.
