Coaxial Cable Question? - job in cords cable

Well, I have no idea what I'm saying Please bare with me. : - /

I decided to rearrange my room and my cable is not long enough to reach the cable-TV, now on the front of my room.

My questions:

Coaxial cable is what I'm looking for?

Do I have purchased additional product in order to join my son to other cables? Or does it work?

So lost. Please help? = /
