Generic top levels domains are meant to be "general purpose domains" and are not generally associated with a particular country. Typically these domains can be registered by anyone, however a few extensions are considered "restricted" which means that a specific group of people are eligible to register then, but are not directly tied to a specific country. These include (but are not limited to) .COM, .NET, .ORG, .BIZ, .INFO, .MOBI, .TRAVEL, .PRO, etc.
