Here’s why:
The two computers will share a single point which requires half duplex comms. Most switches assume full duplex comms. So you might have issues with network collisions and everything will be super slow. Think 50 mbit per second instead of 1 000 mbit per second.
You’ll also potentially lose things due to electrical noise depending on exactly what you use in your solution.
If you just want to tap you’re looking at something similar regarding losing data to noise.
The best and cheapest solution is to buy an unmanaged switch. Avoids data collisions, preserves electrical signal integrity, and allows for traffic to not be spammed all over the network because it’ll send traffic to the correct location (after it’s learned where the “correct” location is).
So, you want a switch (as others have stated).
