NETWORK DEVICES

1-LAN CARD
2-HUB
3-BRIDGE
4-ROUTER
5-BROUTER
6-GATEWAY
7-MODEM


LAN CARD :-
1-Address
1-Ports

Physical Address
1-MAC(Media Access Control)
2-NIC(Network Interface card)
3-Ethernet Address


Logical Address & IP Address
1-Static
2-Dyanamic
3-APIPA(Automatic Private IP Address)

PORTS:-
1-Physical Port-Where we connect RJ45 LAN cable.
2-Logical Port(Total Ports=65535)




2-HUB:-
             Non intelligence device,It Provide share Bandwidth.



TYPES OF SWITCH
1-Store & Forward(Quality,performance,Costly & slow)
2-Fragnent free(First 64bytes repair 7 other direct forward)
3-Cut-through(Normal type of switch,No costly)



STATIC ROUTING:-Static Routing is the process where Administrator manually adds route in each routing table.


DYNAMIC ROUTING:-Dynamic Routing protocol finds the best route on the basis of metric.


LOGICAL PORT:-

    21: File Transfer Protocol (FTP)
    22: Secure Shell (SSH)
    23: Telnet remote login service
    25: Simple Mail Transfer Protocol (SMTP)
    53: Domain Name System (DNS) service

    443: HTTP Secure (HTTPS)

IANA- Internet Assigned Number Authority
                                                                      The Port are divided into three ranges.
1-The well known ports
2-The registered ports
3-The dynamic or private ports



3-BRIDGE
                  Network device bridge connects two or more seprate computer network together to unable communication.
It connects two or more local area network.


4-BROUTER
                     Brouter are combination of bridge and router.it function as bridge as well as router.It filters the data and re-direct to dedicated network.

5-GATEWAY
                     Gateway is a device which is used to connect multiple network and act as a gateway between different network to take entry or exit from the network.

6-MODEM
                  Modem is a device which converts the computer digital signal to analog signal and analog signal to digital signal.
