In a legacy network environment where devices communicate using a shared medium, which device amplifies incoming signals and rebroadcasts them to all connected nodes, often leading to data collisions?
A hub amplifies incoming signals and rebroadcasts them to all connected nodes, creating a shared medium for communication that can lead to data collisions. A switch reduces collisions by creating a virtual point-to-point connection between sender and receiver. A bridge connects and filters traffic between two network segments, and a wireless LAN controller manages multiple access points but does not create shared communication mediums like a hub does.
