vector art

hi all, been in the community for a short while and been hearing and seeing wonderful works done by vector art. i'm a lilttle confused and completely lost about this art. Is it a  new form of drawing or its a kind of drawing done in corel. do i need to use corel for a long time before i start with vector drawing. help really needed cos its ben bothering me for a while. would greatly appreciate it if someone directs me. thanks
