To make it a bit clearer to the uninitiated, it should be said that the top-level domain is what generally comes after the domain name, for example .com (conceptinfoway.com). Every country has its own top-level domain, even if not all of them is used on the Internet. There's also a couple of general/international top-level domains (e.g .com, .net and .org). Even more general/international are being developed and will be applicable sometime under 1998. Most top-level domains have different regulations and fees for use of domain name under their top-level domain.
