basic networks

Type of networks
Local area network - LAN
Wide area Network –WAN

Local area connection
LAN these networks designed for small geographical areas
such like office and home, internet cafe’s, etc

Wide area Networks
WAN these networks using for larger geographical area communicate
Such like internet (DSL), dial up, ISDN


Lets learn about how to setup
Step 1
We need have two or more computers with network card














Before you go to next step we need to know about cabling...

For network we are use many kind of cables
Copper, fiber, coaxial, power cables (main power)

Copper cables better for local area network when you consider speed and cost of the network so we better use copper cables other all will discuss later

Ex: copper cables its call CAT5, CAT6,

CAT5 cables has eight pairs you can see picture bellow
Connectors for CAT5
We need to use connectors to terminate both end of the cable
That connectors is call RJ 45 connectors
We need to crimp cable in order to RJ45 connector (see below)
After crimp it properly you can check your cable using cable tester
See ‘cable tester image’

At least you need to make two cables like this we call it straight cable (see cable concept picture)
Then you need to net work switch or hub to connect two each other
Network hub –network hub how its works
Basic hub are just a device with number of network ports 4prts,8 ports,16ports,it communicates each other ports see “network HUB picture”

You can connect 2 ends of PCs(in network port)and other end to network hub
Go to control panel network (in vista network sharing center) double click and find manage network connections in left side pane
And go to local area connection right click and chose properties in that property you can see TCP/IP protocol in default you can see its autos that you need change to manually assign

(See picture network) then we need to assign IP address (about IP address see ip address tab)
Now we will enter this TCP/IP number -192.168.1.1
Subnet mask-255.255.255.0
Do change same second computer and change it to this TCP/IP -192.168.1.2
Subnet mask-255.255.255.0
