True or False: A switch can be said to segment collision domains in a network.

A switch can indeed be said to segment collision domains in a network. This statement is accurate because switches operate at the data link layer (Layer 2) of the OSI model and manage data traffic by creating separate collision domains for each of their ports.

In a traditional hub-based network, all devices share a single collision domain, meaning that if two devices transmit data simultaneously, a collision occurs, resulting in data loss and the need for retransmission. Switches alleviate this issue by allowing each connected device to communicate without interfering with others, as they only forward data to the specific port where the destination device is connected. This isolation effectively reduces the chances of collisions, enhancing network performance and efficiency.

The ability of switches to segment collision domains plays a crucial role in larger networks, especially in environments with high traffic, as it enables scalability and reliable data transmission.
