To connect computers you need source network :
1.Hub (Not secure )
2.Switch
Router is to connect different network
Ethernet is Topology (Method to connect each
other computers ) More à Topology Network!
Kinds of Ethernet
1.Ethonet 10Mb/s use 4 wired (orange,orange white, green ,
green white)
2.Fast
Ethonet100 Mb/s use 4 wired
(orange,orange white, green , green white)
3.Giga Ethernet 1000 Mb/s (1gb) all wire used
Bus Topology
To Connect the devices we need:
Cables
-Straight
Cable à To connect different
devise PC à Switch
Router à Switch
PC à Hub
To Connect device , should be same color
coding. There 8 colors coding in common.
-Cross
Cable
à Same Device
Router to Router
Router to PC
Switch to Switch
Hub to Hub, Hub to Switch
Cross cable for giga ethernet
How
to create ethonet with the straight cable.
Correct wire color coding
1.orange
2.orange white
3.Green
4.Blue white
5.Blue
6.Green White
7.Brown
8.Brown white
Take RJ 45. There are 8 pins on it…so
take the cable colors out and separate into 8 pieces, straighten it, put the
pin facing u and put the cables into each pin…cramp it. The right connection
will connect 1 to 1 , 2 to 2 and so on.
Note
: To create Giga ethonet..it must connect whole wire so it can get 1gb/s.

How
to change IP Adress
Control panel-Network & Internet –Network &
Sharing center-LAN-properties-Internet protocol v4-Properties-use following IP address-change
the ip-write subnet mask
To identify subnet mask :
19.50.10.2 à this is class A
where 1 bit is Net id (255) and 2-4 is
host id (0)
255.0.0.0 so
it becomes this subnet mask
192.168.20.30 à
class c where 1-3 is Net id (255) and 4 is host id (0)
255.255.255.0 so it
becomes this subnet mask.
