The presence of of a link light indicates that the transmit and receive pairs are properly aligned and the connected devices are communicating.
Link light
A crossover cable is used to connect a Hub or Switch to another Hub or Switch - or a PC to another PC.

Port in hub/switch refers to the interface where you connect your computers.
it is a switch in hubs
A hub, a switch, a router. They are all what you have described. A hub is a central point of a computer network. A switch is a series of ethernet ports with no wireless functionality. A router can have both wireless and wired capabilities, but can also have a modem built in.
Hubs and Switches make 1 ethernet connection out of as many is on the hub or switch.

I suggest a hub as they are more reliable.
Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports. That makes the hub inefficient - in a hub, only one computer can transmit at a time.Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports.

This is actually just a modem. A hub is a device with multiple ports for connecting computers to each other. A hub is now rarely used as a network switch is a faster more reliable device. Confusion comes from people like BT who supply what they call a home hub, which is actually a wireless router, they use the term home hub to refer to the central point (as in hub of a wheel) connection, probably because it's bright young designers never heard of a network hub! A modern wireless router normally consists of a combined router, 4 or 5 port network switch and wireless access point in one, and a non wireless one is the router and network switch Mohammad Talha 009746411902
