The term 'PART OF AN INTERNET ADDRESS' can be broken down into two parts: WWW and DOT. WWW stands for World Wide Web, which is the system of interlinked hypertext documents that are accessed via the Internet. DOT stands for Domain Name System, which is a hierarchical decentralized naming system for computers, services, or other resources connected to the Internet or a private network. Together, WWW and DOT form the basis of an Internet address.
