Advantages: Dependent on the central hub, if it fails the entire network goes down. Disadvantages: Easy to install and manage, if one device fails it does not affect the rest of the network.
Advantages: Requires minimal cabling, if one device fails it affects the rest of the network. Disadvantages: Easy to install and manage. Data travels slowly.
Advantages: Easy to install and manage, if one device fails it does not affect the rest of the network. It is scalable and data travels pretty fast on it. Disadvantages: Dependent on the central hub, if it fails the entire network goes down.
Advantages: Difficult to install and manage, if one device fails it affects the rest of the network. Disadvantages: Not dependent on the central hub, if it fails the entire network goes down.

Circular network
Linear network
Star-shaped network
Explain the advantages and disadvantages of using Ring Topology.
Advantage: Ring Topology is the most secure and reliable network topology. It is scalable and fault tolerant. Disadvantage: It is expensive to set up and data travels slowly along it.
Advantage: Ring Topology allows for easy identification and isolation of network issues. It is fault tolerant and cheap to set up. Disadvantage: It is not scalable and there is a single point of failure.
Advantage: Ring Topology is the fastest and most efficient network topology. It is scalable and complex. Disadvantage: It is not redundant and it is expensive to set up.
Advantage: Easy and cheap to install. and it provides equal access to all devices. Data travels quickly and it has some redundancy, though not a lot. Disadvantages: Single point of failure, not fault tolerant and not scalable.
What is the main characteristic of a Mesh Topology?
There is no connection between nodes
Each node is connected to only one other node
Each node is connected to many other nodes
Nodes are connected in a circular fashion
Explain the advantages and disadvantages of using Mesh Topology.
Advantages: Medium reliability, some fault tolerance, moderate scalability, and can handle moderate traffic loads. Disadvantages: Moderately expensive to implement and maintain, somewhat complex to manage and configure.
Advantages: High reliability, fault tolerance, scalability, and can handle heavy traffic loads. Disadvantages: Expensive to implement and maintain, complex to manage and configure.
Advantages: Low reliability, no fault tolerance, limited scalability, and cannot handle heavy traffic loads. Disadvantages: Inexpensive to implement and maintain, simple to manage and configure.
