What is the primary function of a network hub?

The primary function of a network hub is to connect multiple devices in a network. A hub is a basic networking device that serves as a central point through which data is transmitted between connected devices. When one device sends data to the hub, the hub broadcasts that data to all other devices connected to it, allowing them to receive the information. This makes it a simple yet effective way to facilitate communication within a local area network (LAN).

While managing network traffic efficiently is an important aspect of networking, hubs do not perform intelligent traffic management like switches do; they simply transmit data to all ports without filtering or directing traffic. Storing data for network clients is a function of storage devices or servers, and providing software updates is typically handled by dedicated update services or management systems. Thus, the correct focus on connecting devices emphasizes the fundamental role a hub plays in establishing a network.
