What describes the function of a network hub?

A network hub serves as a central connection point that facilitates communication among various devices connected to a local area network (LAN). Its primary function is to receive data packets from one device and then broadcast that data to all other devices attached to the network. This allows the devices to communicate with one another, effectively acting as a central location for network connections.

While it is important to note that a hub does not manage traffic intelligently like a router or switch—meaning it does not direct the data or prevent collisions—it plays a critical role in enabling connectivity within a network. This basic yet essential role of the hub underpins the functioning of many simple networks.

In contrast, routing decisions and traffic management are functions associated with more advanced networking devices, such as routers or switches. A hub does not have any capability to eliminate collisions; instead, it can actually exacerbate them in busy networks due to its broadcasting method. Additionally, providing internet access is not a function of a hub; rather, it is typically handled by a modem or router that connects to an Internet Service Provider (ISP).
