Network Hubs are devices used to help connect computers and other network devices together. They act as a central point of connection for all devices on a network and enable them to communicate with each other. Hubs are commonly used in Local Area Networks (LANs), where they are used to connect computers, printers, routers, and other network devices.
When a computer or other device sends a signal, the signal is broadcasted to all connected devices. Hubs do not provide any filtering or routing of the signal, but instead, simply direct the signal to all connected devices. Hubs are considered to be “dumb” devices, as they provide no intelligence or logic as to which device should receive the signal.
Hubs typically have multiple ports, which allow multiple cables to be connected to the hub. These cables can be used to connect the hub to other devices on the network. The most common type of cable used is the Ethernet cable, which is used to connect computers, routers, and other network devices. Other types of cables, such as Fibre Optic cables, can also be used when higher speeds or longer distances are needed.
In addition to providing a central point of connection, hubs can also help to extend the range of a network. By connecting multiple hubs together, the range of the network can be increased. This is especially useful for large networks, such as those found in businesses and universities.
Overall, network hubs are an important part of any network, and are necessary for the proper functioning of the network. They provide a central point of connection for computers and other network devices, and allow them to communicate with each other. Moreover, they can also help to extend the range of a network.
