Question 33


Describe in Detail


What are the two types of transmission technology available?


Broadcast Network

  • Broadcast networks have a single communication channel shared or used by all the machines on the network.
  • Short messages called packets sent by any machine are received by all the others.
  • Use a special code in the address field for addressing a packet to all the concerned computers.
  • Some broadcast systems support transmission to a subset of the machines known as multicasting.
  • On receiving a packet, machine checks if the packet is addressed to it then the packet is processed, otherwise it is ignored.

Point-To-Point Network

  • Point to point networks consists of many connections between individual pairs of machines. To go from the source to the destination a packet goes through intermediate computers before reaching the desired computer.
  • Since packets follow multiple routes, of different lengths, routing algorithms are very important in the point-to-point networks.

An important general rule is that localized networks (e. g. LAN) tend to use the broadcasting; whereas networks over wide geographical areas (such as WAN, Internet) use point-to-point transmission.
