NOTABLE POINTS IN ICT

The internet and the World Wide Web (www) IS NOT 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 the World Wide Web

Types of Networks Based on Geographical size

  1. Personal Area Network (PAN): An instance is a Bluetooth connection between two devices.

  2. Local Area Network (LAN): This is the network under a single administrative control and usually within a building.

  3. Campus Area Network (CAN): This network connects various devices within a campus or college

  4. Metropolitan Area Network (MAN): This network connects two offices/companies within a city

  5. Wide Area Network (WAN): This network connects devices throughout the globe. The internet is a typical example of a WAN.

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 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 internet (and with a single IP Address). The term associated with this process is referred to a Network Address Translation (NAT)
