Question 2

Answer 2.1

In this particular approach, the various topologies have been stated with their advantages and weaknesses:

1. Star Topology

Strength: Centralized and easy to operate with proper isolation of each device

Weakness: Central hub services if critical can result in total network shutdown

2. Ring Topology

Strength: Passage of data is transparent and provides better accountability in comparison

Weakness: If a single node is un-operational, the entire network might start to create issues

3. Bus Topology

Strength: Most easy installation and cost-effective compared to other networks

Weakness: The network structure is not viable in case of a huge number of nodes

4. Mesh Topology

Strength: Point-to-point operational contact is done to ease the data transactions

Weakness: Significantly higher complexity often leading to unused connections

Answer 2.2

1. Star Topology

Ease of Installation: Fairly easy to install through one centralized structure

Performance: Operates efficiently if the central hub is functional

Cost: Very Low Cost

2. Ring Topology

Ease of Installation: Fairly easy to install through simple circular structure

Performance: Performance is not very high as the speed of such network is slow

Cost: High Cost

3. Bus Topology

Ease of Installation: Highly easy to implement through simple structure

Performance: Performance is very low as it is not a viable structure for large networks

Cost: Low Cost

4. Mesh Topology

Ease of Installation: Highly complex installation and is not at all easy

Performance: Very high performance related to the systems complexity and application

Cost: Very High Cost

Answer 2.3

In the consideration of providing redundancy operations, these aspects need to be quantified through proper analysis of each of the topologies under management. In these particular operational systems, the relative perspective of trouble-free operations can be implemented with proper determination and judgment. In terms of the cost-effective nature of network and ease of operational construction, the bus topology tops all other network topologies. In case of the fastest operational might and secure data application, Mesh Topology tops others. While in case of best accountability, it is always more secure through Star Topology.

Answer 2.4

In case of limited wireless network operations, various topologies would be essential as usual. However if there are less resources for a network setup, then Bus Topology would be essential. The operational structure of Bus Topology has been associated with proper determination of simple application of network and their options. The use of basic devices would be essential for the operational designing and development of a limited wireless network application.

Answer 2.5

1. Bus Topology

In case of Bus Topology, the cost of operational structure of the network is les as a single main network connection from the server is able to serve various nodes within the internal network of the systems.

2. Ring Topology

In case of Ring Topology also, the cost is fairly less as the connectivity of the network is single and simple. The ring topology structure is related with basic use of devices and server systems with the nodes.

3. Mesh Topology

The cost of operation is significantly high as the various nodes are independently connected to each other. Use of physical connectivity for such network structure requires advanced server applications within higher expense.

4. Star Topology

The cost of operation for Star Topology is also highly anticipated. Star topology operates mainly on a centralized management server system. This centralized systems needs to be operated with proper security and expense.
