When Should a Network Switch be Used Instead of a Hub?

Answer: A network switch should be used instead of a hub for improving the performance, reduced collisions, and better security in modern network environments.

Below are the scenarios in which network switch can be used instead of a hub.

Scenario 1: Segmentation

When dividing a network into multiple segments, a switch make sure that the network traffic is only sent to the desired destination, which reduce congestion and improve network speed. This is important in larger networks where multiple devices communicate in same time.

Scenario 2: Bandwidth Management

Switches provide proper bandwidth to each port, allowing devices to communicate at their maximum speed without sharing bandwidth with other devices.

Scenario 3: Collision Avoidance

Switches use a method called store-and-forward to process data packets, this reduce the chances of collisions and packet loss. This is important for maintaining a reliable network.

Scenario 4: Security

Switches create individual collision domains for each port, this prevents unauthorized access to network traffic.

Scenario 5: Quality of Service (QoS)

Switches support QoS mechanisms, this allows the administrators to prioritize certain types of traffic, such as voice or video data, for optimal performance.
