The maximum speed supported by the router or the network card is usually defined on the back of the device in question.

The IP address of our computer is roughly the identification number of our PC in a network. When we are connected to the Internet, all devices have two types of IP, a public one, which corresponds to the router's IP address, and a private one, which matches the identity of our device (computer, tablet, mobile, etc.). Currently there are still many doubts regarding the IP address. "What is my fixed IP", "how to change the IP address", "what public IP do I have", "how to change the public IP", "how to know the IP of the router" .
