Study the functioning of switches

A switch is used in a wired network to connect Ethernet cables from a number of devices together. The switch allows each device to talk to the others. Switches aren't used in networks with only wireless connections, since network devices such as routers and adapters communicate directly with one another, with nothing in between.

How to configure and install LAN card

If you want to add your computer to a network or a network device like a router then you need to install or configure your network card. Every new computer and motherboard you buy nowadays has a built in network port known as RJ45 socket. If you have an older computer or a motherboard that does not have a built in RJ45 socket then your only option is to add a PCI or USB network card if you wish to connect to a network. For this guide i will assume that you do not have a network card installed. If you already have a network card then you can skip step 1 to 3.

Physical media of connectivity

The means through which data is transformed from one place to another is called transmission or communication media. There are two categories of transmission media used in computer communications. (1) Bounded/Guided Media. (2) UnBounded/UnGuided Media

Functioning of Hubs, Bridges and Gateway.

Hubs, Bridges, Switches and Routers are used to build networks. If you are trying to design your own LAN (Local Area Network) at home, then you probably need to know what they do and the main differences between them. I will try to cover all that in addition to some networking details to cultivate the article and provide better understanding of how the internet works. After all, always remember that the internet as you know it is nothing more than a network of networks!

LAN Topologies

In Computer networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.
The physical topology of a network is the actual geometric layout of workstations. There are several common physical topologies like Bus, Star, Ring, Hybrid topology.

Different type of LAN technologies

A local Area Network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines.
