1 . LAN CARD (NIC- Network interface card ) – is a network device which use to make the connection in between computer to computer as well as other device 

èWired LAN card :-

·          10 base 2 Lan card – used with coaxial cable (10 base 2) BNC 10 mbps.

·          10 base 5 Lan card – used with coaxial cable (10 base 2) AUI 100 mbps.

·          10 base 3 lan card – used with TP cable RJ45 10 mbps

·          100 base T lan card – used with TP cable RJ 45 10/100 mbps

·          Gigabyte lan card – use with TP  cable RJ 451 gbps to 100 gbps

2 . Repeater -: It is a Network device which use to Regenerate or amplifier the signal

èIts use with Coaxial cable

èIt use two LAN segment at a time

èIt is non intelligent device because it does not understand the LAN card MAC address.  It create the collision 

3 . Bridge -: It is a Network device which use to regenerate or amplifier the signal

èIt is an advance version of repeater

èIt connect the multiple lan segment at a time (up to 8)

èIt is an intelligent device because it understand LAN card MAC Address

èIt does not create the collision

4 . Hub -: It is Network device which use to make the connection between computer to computer

èIt has 4/8/16/24 Port device

èIn which there two types of port

Up link                                    Non up link

èIt is non-intelligent device because it does not understand the MAC Address

èIt create the collision 

èIt is a broadcast device

5  . Switch -: It is a Network device which use to make the connection or create the connection in between computer to computer

èIt is an Advance version of HUB

èIt has 8/10/24/48 port device

èIt is an Intelligent device

èIt is uncast device

6 . Router -: It is a Network device which use to provide the Communication in between tow or more than two Network

                èThere are two types of Router

ð  Software Router (MCITP III module )

ð  Hardware Router ( CCNA Module IV )

7 . Gateway -: It is a Network device which use to provide the route or path of traffic or internal network to external network as well as external to internal Network

                Two types of Gateway

ü  Hardware Gateway

ü  Software Gateway

8 Broughter -: It is a Network device which use to connected the multiple LAN segment as well as provide the communication in between two or more than two Network

ü  It is combination of Bridge and Router

ü  It is a Advance version of Bridge

ü  It is intelligent device

ü  It does not create the collision

9 Layer 3 Switch -: It is a Network device which use to make connection in between computer to computer as well as provide the communication in between different  network

ü  It is  a combination of switch and router

ü  It is a advance version of switch

ü  It provide higher performance.  It create the large LAN..

10 Modem -: It is a network device which used to complete the modulation of de-modulation process   It means it convert analog signal to digital signal and digital signal to analog signal

11 . Access Point -:  It is a wireless
