A switch is a network device that is responsible for separating collision domains.
In computer networking, a collision domain is a network segment where packet collisions can occur when two or more devices transmit data simultaneously. This can lead to data loss, network congestion, and performance issues. To prevent these issues, collision domains need to be separated, so that only one device can transmit data at a time within a given segment.
A switch is a network device that operates at the data link layer (Layer 2) of the OSI model. It receives data frames from connected devices and forwards them to their intended destinations based on the Media Access Control (MAC) addresses in the frames. By doing so, a switch can create multiple collision domains, with each connected device having its own dedicated path to the switch.
This is different from a hub, which operates as a simple repeater, broadcasting all data it receives to all connected devices, effectively creating a single collision domain. Routers, on the other hand, operate at the network layer (Layer 3) and are responsible for forwarding data between different networks, rather than within a single network.
Therefore, the correct answer is A. Switch.
