A top level domain, when it comes to the internet, is most easily described as an extension at the end of the web pages name. Websites can have all different kinds of endings including .com, .org, or .net and many others. Originally, .org was for non-profit organizations, .com was for commercial websites, and .net was for networks. The ICANN, or Internet Corporation for Assigned Names and Numbers, manages top-level domains. ICANN operates the IANA, or Internet Assigned Numbers Authority, as well. Here is some information about top level domains and how they can affect your company.
