NETWORK
COMPONENT
The following terms are use to describe network component
Ø
NODE / HOST: a node is any device
(such as workstation, server, or printer) that can communicate on the network.
Each must have a unique address. The term Host is often used in
TCP/IP networking to mean the same thing, while a node on a wireless network is
also called a station
Ø
TRANSMISSION MEDIA information must
be transferred between nodes using some form of media. Typically, this takes
the form of a cable but wireless media using technologies such as radio can
provide the same function
Ø
INTRANETWORK DEVICES most network
use extra devices to facilitate connections between nodes. Rather than using
cables to link the nodes directly, each node is connected to an intranetwork devices, such as a switch.
Ø
SEGMENT
are parts of a lager network that are linked together by an
intranetwork device. All nodes on the
same segment use the same type of transmission media and have the same bandwidth
Ø
BANDWIDTH is measured on how much data can be
transferred through a link.
INTERNETWORK
DEVICES
Separate networks can be join using internetwork devices
such as routers. Such networks may use different types of transmission media and protocols.
The term intermediate system (IS) can be used to distinguish
nodes with routing (or switching) capability from End System (ES).
SUBNETWORK or subnet
is a logical grouping of host within a single network. Subnets must use
internetwork devices to communicate.
