Networking concept

Let’s know about basics of Networking concept. In the broadcast sense a

 network is any interconnected group of people or things capable of sharing meaningful information with one another. In a technology context, network is usually short for "computer network" or "data network" and implies that computers are the things sharing the meaningful information.

The network you have at home uses the same networking technologies, protocols and services that are used in large corporate networks and on the Internet. The only real difference between an home network and a large corporate network is the size. A home network will have between 1 and 20 devices and a corporate network will have many thousands.

Networks can be wired or wireless with most networks being a mixture of both. There are many different ways network nodes can be connected together. This isn’t normally a consideration in small networks but has networks get larger it becomes more important.

Common connection technologies like Wi-Fi, Bluetooth etc are designed to work using a particular network topology. When designing networks and choosing connection protocols having an understanding of these topologies is important.

Common are:

·         Bus

·         Ring

·         Mesh

·         Star

·         Hybrid

Each of these topologies has advantages and disadvantages this Network topologies article has a really good overview of each topology along with advantages and disadvantages.

Early Ethernet networks used a bus structure, modern Ethernet networks and Wifi networks. use a star bus (hybrid) structure.
