Final answer:
A tree topology is a network configuration that uses a single cable as the backbone for communication with all devices in the network. It combines features of star and bus topologies and is suitable for groups of computers located in close proximity.
Step-by-step explanation:
Tree topology is a network configuration where a single cable serves as the backbone for communication between all devices in the network. It combines the features of star and bus topologies. Data in a tree topology travels in a circular pattern from one computer to another, making it ideal for groups of computers located in close proximity.
