Your internet cable is small copper wire smaller than a paper clip. And just like a paper clip, if you move it back and forth, it will break. When it breaks and it will, you will never know it, the device will just stop working. To help stop the wire from breaking, proper termination is required. The proper way to terminate the connector is to make sure that the sheathing is crimped in the connector to prevent damage.
Why are we talking about wires?
Wires that come straight out of the wall or ceiling instead of using a wall plate can be damaged very easily. To repair the wire a technician will need to repair it. During that time the device will be down and you can not use that printer, terminal, etc.
All you need is a patch cable
To repair the device all you need is a patch cable that you can get at a hardware store.
With a wall plate all you have to do is replace the patch cable and your employees can get back to work.
Outside covers will help protect your wires.
Wall plates make the data drops easier to identify.
