How to find out by what standard the network card works (Fast Ethernet \ gigabit ethernet), from under windows?
Provided that we do not know the maximum throughput of the port where the network card is connected.

Answer 1

Provided that we do not know the maximum throughput of the port where the network card is connected.

The question is, of course, a trick. Not by standard means. Most likely, special programs are needed. Or the name of the network card itself should contain the maximum speed.
This is what a gigabit network card connected to a 100 megabit port shows.
But when the cable is not connected, the logic changes

Answer 2

You can also look at the LED at the port, one is responsible for the link, the other for data transfer. So if green means up to 100, if orange then up to 1000.

Answer 3

Isn't it?

Answer 4

at what speed that standard works and is used. Writes 100Mbps means 802.3u, if 1000Mbps is 802.3ab. If it is not connected to anything, then no standard is used.
