Star wiring diagram is among the most popular network topologies used in the computer networking field. It is a network configuration that has a central point or hub, which is connected to individual nodes or devices across the network. The central point, also known as the hub, is usually a switch or router, while the nodes are devices such as computers, printers, servers, and other networking equipment.
Advantages of Using the Star Wiring Diagram
Advantages of using the star wiring diagram in computer networking include:
1. Easy to Install and Manage
Star topology is simple to install and manage since every network device is connected to a central point. Adding new devices to the network is also easy since you need to connect the new device to the central hub or switch. Managing the network is also easy since you only need to monitor the central hub or switch for any possible issues.
2. High Reliability and Performance
The central hub or switch used in the star topology is usually designed to provide high reliability and performance. This means that the network can handle a high data transfer rate without causing any significant delays. Also, since every node is connected to the central point, the failure of one device does not affect the entire network, making it more reliable.
3. Scalability
The star topology is highly scalable since you can add more devices to the network by connecting them to the central hub or switch. This makes it ideal for use in large organizations that have many devices on their networks.
4. Easy to Identify Faults
Star topology makes it easy to identify and isolate faults on the network. When a device fails or experiences an issue, the central hub or switch can quickly identify the affected device, making it easier to troubleshoot and fix the problem.
5. Security
The star topology is considered to be more secure than other network topologies such as bus and ring. This is because every node or device is connected to the central hub, making it difficult for unauthorized users to access the network.
Disadvantages of Using the Star Wiring Diagram
The star topology also has some disadvantages that include:
1. Costly to Implement
The star topology is relatively costly to implement, especially when compared to other network topologies such as bus and ring. This is because every device needs to be connected to the central hub or switch, which can be costly, especially for large networks.
2. Dependency on Central Hub or Switch
In the star topology, every device is connected to the central hub or switch. This means that if the central hub or switch fails or experiences an issue, the entire network can be affected, causing significant downtime and loss of productivity.
3. Limited Distance Coverage
The star topology has a limited distance coverage since every device needs to be connected to the central hub or switch. This means that the network can only cover a limited distance, making it unsuitable for large geographical areas.
4. Complicated Cabling
Implementing the star topology requires complicated cabling since each device needs to be connected to the central hub or switch. This can be time-consuming and requires skilled personnel to manage the cabling.
5. Limited Compatibility
The star topology is not compatible with all types of devices. Some devices such as printers and scanners may require a different network topology, making the use of the star topology limited.
