What are the similarities and differences between bus and tree topologies? Similarities :

Answer :

Physical or Logical Network Topologies

With the brief introduction provided above, we simply understand what a basic computer network is all about.

A network topology can either be the physical or logical arrangement of devices on a network.

These connected devices can be routers, switches, firewalls, network printers, wireless access points, user computers etc (basically anything that can be assigned an IP address). Note that end user devices are also part of the network topology.

Logical topology deals with how data is transferred and flows on the network, while physical topology is concerned with the physical layout of the devices on the network and how they are physically connected.

Types of Network Topologies

Network topology goes beyond logical or physical arrangement of devices. This brings us to the various types of network topologies available today. These topologies are Bus, Star, Ring, Tree, Hybrid and Mesh network topologies. Let us take a closer look at each of these types mentioned.

Bus Topology – Advantages and Disadvantages

Bus topology has a network arrangement where nodes make use of a single communication line for data transmission.

Many networks at the beginning of computer networking era made use of this topology due to easy implementation.

Advantages

• Since there is a single communication line, means the same medium is shared. Therefore, the major advantage of using this topology is its simplicity.
• Easy to setup and extend.
• Less costly. Less cabling needs.

Disadvantages

• On the other hand, having a single communication line for data transmission makes it easier for collision to occur, which is seen as a disadvantage of using this network topology.
• If the single network cable has a problem or disconnection, the whole network breaks.
• Difficult to identify a problem.
• All devices receive all signals from every other host. This is not efficient.
