Gigabit ports working together with 100 Mbps?

Question

Computer networks

Good afternoon, will a gigabit card of computer A connected to a gateway with a gigabit card through a gigabit switch port work and at the same time computer B with a 100 megabit card connected to the same gateway through a 100 megabit switch port in the same network? Will there be different speeds or will everything drop to the minimum fast ethernet of 100 Mbps because of Computer B?

Answer 1

Everything that works at a gigabit speed will work at a gigabit speed
Everything that works at a speed of 100 mb / s will work at a speed of 100 mb /
s

Answer 2

It will be no problem, each at his own pace. On modern switches, each channel exchanges independently, and the internal bus is designed for much more flow than one channel can provide in any mode.

Answer 3

At what speed network interfaces agree to work, each joint will work at this speed. The lane between A and B will depend on all intermediate sections and will not become faster than the slowest section.
The switch has independent ports - one can work with FE, the other can work with GE.
rs: computers in standby mode can generally transfer the network interface to 10mbps and nothing, the network does not die from this.

Answer 4

One more nuance should be noted ... In gigabit networks, the minimum packet size (in length, in a wire) is the same as for 100 megabits. But gigabit networks can combine several small packets into one large one. Therefore, if the switch is not completely left-handed and knows how to do it, then everything is ok.
But if it is a little blunt, then with a dense stream in the form of a bunch of small packets from the 100-megabit network, the gigabit part will also be packed to capacity.
