Swapping bishops for knights

Ok,going to tie a few things into this post - firstly hello, it's my first. I'm pretty new to chess, so all the phrases and shorthand is a bit above my head at the moment. I was wondering though, when I'm playing people (computer esp) will swap their bishop for my knight as soon as possible, if my knights on c3 or something. Was just wondering what the obvious advantage to doing thing was? Sorry if this questions a bit of a 'how longs a piece of string'' feel free to point me to a pages with basics like this if you know of one. Cheers!
