Packets, routers and IP addresses

  1. 1. The Internet a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.
  2. 2. Domain names and IP address’ • A Domain name is what you type in to navigate to a website. • The IP address is the ‘real’ address and it made up of numbers and dots for example 123.23.234.45. • We use domain names instead of IP addresses when finding a website as for most people it is easier to remember words instead of a combination of numbers and dots.
  3. 3. Data Packets and Packet Switching. • A packet is a basic form of communication over a digital network it is also called a datagram, a segment, a block, a cell or a frame. It travels along a given network path. • Packet switching is a type of data transmission where the data is split into a number of parts which are sent individually and put back together when it reaches the destination.
  4. 4. The function of routers • Routers determine where information should be sent from one computer to another. • They send your information and messages through thousands of pathways to their destinations. • They also make sure information doesn’t go somewhere it isn’t needed and makes sure it does go to the right place.
