Procedures of making LAN

In this article , i want  to explain the concept of LAN and procedure of making LAN.Simply LAN is a abbreviation of local area network and explain as area in a 100 meters of network is called LAN or local area network.

Procedures of making LAN

                   Following are four procedures use in making LAN.

1)Ethernet

2)Token Ring

3)FDDI

4)Local talk(use only for apple computers)

1)Ethernet:

Interchange of data locally is called ethernet.

Attach LAN card in all computer.

we have to use central entity.

It can be hub or switch.

Following are types of making ethernet LAN.

!Star topology:We can make  ethernet LAN through star topology.Topo means network and logy means study

1) Central entity use in star topology

2) RJ45 connector use in it.

3) Use LAN card which support this technology.

4) It has IEEE 802-3standard .

5) single point of failure.

6) Multiple point of failure

!Token ring topology:

1) Logically entity in Token ring.

2) To share data  ring topology  can be used.

3) Maximum 255 computers can be attached

4) To transfer data we use ticket that name is token.

5)Token can move clockwise as well as anticlockwise.

6) Data transfer is slow

7) Other client have to wait for token

8) single point of failure

9) Co_axial cable use in it.

10) BNC connector use in it

11) It has standard 802-5

12) Hacker can break the security.

FDDI:

1) Fiber data distributed interface topology

2)Same topology of ring is use in it.

3)Two token use in it

4)one is clockwise and other is anticlockwise

5) Fiber cable use in  it.

6) speed is high but security also breaak in it.
