Switch or HUB allows us to add more computers in our LAN or existing LAN. Switch or HUB is usually needed when we are networking more than two PCs. Why we need Switch or HUB only when networking more than two PCs? Because, for two PC networking we have crossover connection which does not require any expensive hardware like Switch or HUB. So, it is wise to use crossover connection.

Here we are going to connect more than two PCs, so we need a Switch or HUB. These devices are user friendly, and you don’t need to worry about what configuration these device need. The entire attention should be paid in crimping and IP address assigning. Because if you crimped the cables in RJ45 wrongly, you will need a new RJ45 and good quality of RJ45 cost double of ordinary one. I always recommend you good quality of RJ45 & UTP cables.

If you want to purchase switch or hub devices then please check my suggestion of products below or you can visit my Amazon.com store for more option.

Color code of direct LAN cabling is simpler than the crossover LAN cabling, because there no jumble of wires all goes from one RJ45 to another RJ45 directly. No changes at all.

Here is a simple diagram showing you connection of two RJ45 connectors. As you can see that there is various color of wire denoting the standard color code for cable. This should be arranged in this manner. Left side RJ45 is No.1 & right side RJ45 is no. 2.

RJ45 no. 1 & RJ45 no. 2 will have the wires according to standard color code and there will be no changes.

If you have arranged your wires according to standard color code then crimp them cautiously. Now get ready for the next step which is IP address assigning to your Client & Server.
