Q & A

What is the main topic of the video?

The main topic of the video is networking, specifically focusing on various network topologies and their definitions, advantages, and disadvantages.

What is network topology?

Network topology refers to the specific description of how a network is structured, similar to how a house is designed and built, defining the layout and connections of devices within a network.

What are the five basic types of network topologies mentioned in the video?

The five basic types of network topologies mentioned in the video are Bus, Ring, Star, Mesh, and Hybrid.

What is a Bus topology?

A Bus topology is a linear network structure where all devices are connected to a single cable, known as the 'backbone,' with terminators at each end to prevent signal reflection.

What are the advantages of a Bus topology?

The advantages of a Bus topology include cost-effectiveness due to the use of a single cable, ease of installation, and the ability to extend the network by simply adding more devices to the cable.

What are the disadvantages of a Bus topology?

The disadvantages of a Bus topology include the potential for a single point of failure, where a break in the cable can disrupt the entire network, and limited distance due to signal degradation over long cables.

What is a Ring topology?

A Ring topology is a network structure where each device is connected to exactly two other devices, forming a closed loop, which allows for data transmission in one direction around the ring.

What is a Star topology?

A Star topology is a network structure where each device is connected to a central hub or switch, which facilitates the transmission of data between devices.

What are the advantages of a Star topology?

The advantages of a Star topology include simplified installation and expansion, as adding or removing devices only affects the connection to the hub, and improved performance due to the dedicated path for data transmission.

What is a Mesh topology?

A Mesh topology is a network structure where each device is connected to many other devices, providing multiple paths for data transmission, which enhances redundancy and reliability.

What is a Hybrid topology?

A Hybrid topology is a network structure that combines two or more of the basic topologies, such as Bus, Ring, Star, or Mesh, to create a more complex and efficient network design.
