Hub

Hub is also known as a multi-port repeater due to its similarity with the repeater, though there are specific devices called repeaters. The hub was also used to connect computers and share data amongst them, but it is now majorly used as a repeater to repeat signals from long distances. The hub is known as a layer one device (on the OSI model), likewise the repeater.

Ethernet

Ethernet to the cabling and ports system involved in networking. The network cables are referred to as Ethernet cables, and they are used to connect a computer to all other networking devices or for a computer to computer connection. The most common of which is the RJ45 connector.

In Cisco devices, Ethernet ports on a router or switch are known as fast ethernet ports, most of which are denoted by letters and numbers according to how they arranged. For instance, the first ethernet port on a router is labeled Fa0/0, while that of a switch is Fa0/1.
