Cable tester

A cable tester is a special toy that helps grown-ups make sure that their computer and internet wires are working properly. Just like how you check your toys and make sure they are not broken, grown-ups need to check their wires too.

You know how you have different puzzle pieces and they have to fit perfectly together? The same is true for wires. If they are not connected properly, then the computer or internet may not work. A cable tester helps grown-ups make sure that the puzzle pieces, or wires, fit perfectly.

The cable tester is like a magic wand that checks the wires. Grown-ups plug one end of the wire into the tester and the other end into the computer or internet box thingy. The tester tells them if the wire is connected in the right way and if the connection is good. If something is wrong, the tester will show a sad face, just like when you have a boo-boo.

So, just like how you take care of your toys, grown-ups take care of their computer and internet wires with a special toy called a cable tester.
