ASSIGNMENT QUESTION: define connectivity hard ware.
Write at least 10 example and describe.
Connectivity hard ware is the hard ware that allows computer to be physically connected to
different type of networks. Common connectivity hard ware includes:
1 CONNECTORS:
The connectors is used to terminate cables in order to be plugged into a network interface
card or another network component.
2 MODEM:
The modem enable computer to connect and transmit data over phone lines by converting the
send, the computer’s digital signals to analog and back again for receiving computer.
3 GATEWAYS: this device performs a protocol conversion so that different networks can
communicate even though they speak different languages.
4 CHANNEL SERVICE UNIT:
This is a device that act as a buffer between a LAN and public carriers WAN to ensure
signals placed on the public lines are appropriately timed and formed for the network.
5 MULTIPLEXER:
This is used to share a communication line among a number of users by converting and
combing a signal from multiple users for simultaneous transmission over a single line.
6 ROUTER:
This is an intelligent device used to connect two or more individual networks. When it
receives a signal, it looks up the address and passes it to the appropriate network.
7 HUBS:
This is a central point of connection between media segment enabling network extension to
accommodate more personal computers (PCs)
8 NETWORK INTERFACE CARD:
The personal computer expansion board with its own unique identifier that plugs into a
computer allowing it to be connected to network.
9 BRIGES;
Used to connect two different LANs or two segments of the same LAN by forwarding traffic
between segments.
10 REPEATER:
This is a network device to replicate a signal as it weakens when travelling across a network.
11 ROUTER:
This is short for bridge router and provides the functions of two or more links together. Such
as internet protocol network. A router receives packets and selects the optimum path to
forward the packet to other network.
12 SWITCH: A connection device in a network that functions much like a bridge, but direct
transmission to various work stations rather than forwarding data to all work station on the
network.
13 TRANCEIVER: The name transceiver is derived from the combination of words
transmitter and receiver. It is a device that both transmits and receives signals and connect a
computer to the network. A transmitter may be external or located internally on the NIC.
14 MEDIA DEPENDANT ADAPTER: A MDA is a plug-in module allowing selection
among fiber-optic, twisted pair, and coaxial cable.
15 MULTISTATION ACCESS UNIT: MAUs are special connectors or hubs for use in
Token Ring networks instead of Ethernet networks.
