Today I would like to share with all of you about NETWORK EQUIPMENT..!!
Network equipment consists of FILE SERVER, WORKSTATIONS, NETWORK INTERFACE CARD (NIC), BRIDGES, HUB AND SWITCH, ROUTER AND REPEATER.
First: FILE SERVER-----> stands at the heart of most networks.
very fast computer and large amount of RAM and storage space.
WORKSTATION-------> User computer that is connected to a network.
Almost any computer can serve as a network stations.
NETWORKING INTERFACE CARD-------> Provide the physical connection
between the network and
the computer.
Major factor in determining the speed
and the performance of a network.
3 Most common network interface------>
ETHERNET CARDS
LOCAL TALK CONNECTOR
TOKEN RING CARD.
BRIDGE--------> Monitors the information traffic on both sides of the network so that it can pass packets of
information to the current location.
Manage the traffic to maintain optimum performance on both sides of the network.
ROUTER------->Select the best path to route a message, based on the destination address and origin.
Redirect data around those sections until they clear up.
Direct signal traffic efficiently.
REPEATER------> To boost the signal with a device.
Electrically amplifies the signal it receives and rebroadcast it.
Can be separate devices or they can be incorporated.
HUB-----> Transmit all data received to all node connected to the hub.
SWITCH-----> Identifies the device on the network for which the data is intended and sends the data to
that node only.
Can connect Ethernet, Token ring, Fibre and other packet switched network.
GATEWAY-----> A network node equipped for interfacing with another network that uses different
protocols.
A protocol translation or mapping gateway interconnects network with different network
protocol technologies by performing the required protocol conversions.
here are the video to make all the things more vividly......^^
