Basic networking concepts

This article introduces you with the basic networking concepts which are essential for every person learning about computer science. Hope you have already read about history of computers.

 

Network

A network is a collection of interconnected computers, which are connected using communication media along with communication devices. Examples of communication devices are: modems, routers and bridges.

 

Examples of communication media are: telephone cables, coaxial cables, twisted pair cables and fiber optical cables.

 

Using a network has several advantages like:

  • Easy to share the information.
  • Easy to share the resources like printers etc.
  • Saves time and money.

Network Model

A network model refers to how the computers over the network communicate with each other. The famous networking model is client-server model. In this model there are two types of entities called client and server. A client always issues requests and the server always serves the requests. This can be viewed diagrammatically as shown below:

Topology

The topology of a network refers to the structure in which the computers are interconnected with one another or the arrangement of networking components. Some of the well-known network topologies are mesh, star, bus and ring as shown in the following picture:

Internet

The collection of networks throughout the world which consists of billions of computers is known as internet. Internet can also be defined as network of networks. We can transfer data from one part of the world to anywhere in the world.

WWW (World Wide Web)

The World Wide Web (WWW) is the collection of all the webpages available on the internet. The webpages consists of information in the form of text, images, audio or video. One webpage can be linked with another webpage by using hyperlinks.

World Wide Web (WWW)

 

It is important to know that Internet and WWW are not the same thing. Internet is the carrier and WWW is the content that gets transferred through the Internet.

 

That’s it about basic networking concepts. Now it’s time to learn about basics of programming languages.
