Connecting a PC and a laptop?

Question

laptops

There is a computer connected via cable to the router.
There is a laptop connected to the router via wi-fi. You can not connect the cable to the laptop (there is no connector).

Is it possible to somehow connect them to each other so that you can freely exchange files, use the computing power of devices together (for example, conduct a conference in zoom from a computer, while managing the conference from a laptop and using a laptop microphone, and the power will be used by a computer, with laptop to write code, keep a lot of open windows.)

I want to control a computer from a laptop and a laptop from a computer.

How can this be done?
