I bough a laptop comp.How can this be used at home for internet access etc; I have dsl at home right now? l?

Go out and buy a router. Connect the router to your DSL modem. Then, look on your laptop for your new network (it will probably be named something like default or the name of the company that makes the router). Run the CD that comes with the router and change the name and put a pword on it (so people can't steal your Internet). After that, your computer should connect automatically.
