NOTE

NETWORK TOPOLOGY

A topology for the network is known to be a layout for the connected devices. This is important because this is used to provide a proper flow of data within the said network. Here are the various topologies:

  1. Bus – This is the type of structure that uses a single medium to connect the computer.
  2. Ring – Each computer is connected to another neighboring computer for data transfer. One failed network can cause all networks to turn off.
  3. Star – This is a structure that’s common in homes. It uses a certain hub or a router to make the network possible.
  4. Tree – This is a complicated structure that connects the star into multiple buses. This is common for internet cafes and offices.
  5. Mesh – this is a connection that leads to various data transmissions which are perfect for routing huge networks.

EVALUATION:    1. Define network topology

  1. List and explain four types of network topology
