Node |
A computer on a network. Identification are associated with a node. So that computer can be identified. Allowing sending and receiving of data. |
|
|
Hub |
An electronic device used in networks. Helps disconnect faulty cables. Can also be referred to as bridge or repeater. |
|
|
Modem (Modulator/Demodulator) |
A common computer which allows home connections to the internet ovee phone lines or cable. Changes signals into digital signals. |
|
|
Repeater |
An electronic device which performs many functions in a network. Strenghtens a signal, takes generallly very little time to work and output signal. |
|
|
Router |
An electronic device which sends and receives signals. Can connect many LANS together. It has an adress to associate different computers. |
|
|
Bridge |
An electrinic device which connects two LANs together. They do not have adresses but can relay signals. |
|
|
Server |
A larger computer containing vast quantities of data. Sends and receives data to computers. |
|
|
Segemnt |
A segment is any portion of a network that is seperated by a switch bridge or other parts of a network. |
|
|
Backbone |
Bigger version of a segemnt carries more data anlt higher rates. |
|
|
Topology |
Is the way that each node is connected physically connected to a network. |
|
|
LAN |
A network of computers in the same general area physcially. If they are further they are called WAN (Wide Area Network). |
|
|
Network Interface Card |
Every computer is connected through a NIC. |
|
|
Media Access Control |
This is the physical address of any device. |
|
|
Unicast |
A transmission from one node to another. |
|
|
Multicast |
Sends a signal to a specific special group. |
|
|
Brodacst |
Sends a signal to all nodes in a network. |
|
|
Bus |
A group nodes daisy changed along the same backbone. At each end of the bus the signal must be terminated. |
|
|
ISO |
International Organization of Standards. |
|
|
Twisted Pair (Topology) |
Long distance, low volume transmission. |
|
|
Coaxial (Topology) |
Longer distance, Greater volume of Data. |
|
|
Fibre Optic (Topology) |
Very large volumes of data, limited by geography. |
|
|
Terrestrial |
Longer distance, large volumes of data, limited by geography. |
|
|
Satellites |
