Answer 1

Hmm. If there is water tank with 1000 gallon water in it.
There are 10 water tap outlets.

Those 10 water taps are connected to water tank with single pipe. That pipe has limited capacity to transfer water. If you open all 10 tap outlets. Water will come out slowly.

Main bottleneck is usually the transfer pipe. In your case internet speed will be divided into multiple outlets slowing it for single user.
