NOTABLE POINTS IN ICT

Computer Network is a group of computers that are linked to each other such that they can share resources.

Generally, these groups of computers that form a network are called nodes.

Some of these nodes will function to store information which will be served to other computers. The nodes that function to store and serve such information are known as servers.

Some of the computers (nodes) will request information from the server. The computers that functions to request information from the server are known as clients.

The internet and the world wide web (www) isn't the same thing.

The internet is formed from the joining or linking of different networks.

For instance, Google's network, Facebook's network and Yahoo's network are among the many other networks that make up the internet.

World Wide Web on the other hand is a collection of linked pages (for instance, this page you're on).

There are actually billions of linked pages in various servers around the world.

You require the internet and a web browser to get to access the World Wide Web

Functions of a router:

  1. They ensure that data (preferably called packets) make it to their intended destination.
  2. They ensure the security of data to some extent.
  3. When a network becomes too big within a Local Area Network (LAN), routers are used to separate such networks.
  4. They connect different networks. This is the very reason why you are able to access the internet. (The internet's network and your service provider's network are different; but thanks to the router for connecting them).
  5. Multiple devices in the home or office can access the internet through the router, (and with a single IP Address). The term associated with this process is referred to a Network Address Translation (NAT)
