Question: 1 / 400

A star topology in networking primarily uses which component to manage connections?

Hub or Switch

In a star topology, the central component responsible for managing connections between all devices in the network is the hub or switch. This configuration consists of a central node, typically a hub or a switch, which acts as a point through which all devices communicate. Each device is individually connected to this central node, allowing for efficient data transfer and management of network traffic.

Using a hub or switch facilitates the isolation of issues; if one connection fails, it does not disrupt the entire network. In contrast, a router primarily deals with directing data between different networks rather than managing individual connections within a single local network. A repeater amplifies signals to extend the network's range, while a modem connects the network to the internet but does not manage local connections. Therefore, the hub or switch is essential for the effective operation of a star topology.
