What is the primary function of a hub in a network?

The primary function of a hub in a network is to connect multiple devices. Hubs serve as networking hardware that enables various devices, such as computers and printers, to communicate with each other within a local area network (LAN).

When data is sent to the hub, it broadcasts that data to all connected devices rather than directing it to a specific device. This means that while a hub connects multiple devices, it does not have intelligence in the data transfer process or manage the traffic. Hubs operate at the physical layer of the OSI model, and their main role is to facilitate communication between devices on the same network segment, which is essential for creating a functional network environment.

In contrast, options such as managing bandwidth, storing data, or assigning IP addresses are functions typically associated with more advanced networking devices like switches, routers, and servers, which perform specific roles that a basic hub does not address.
