| Sever | a computer program running to serve the needs or requests of other programs (referred to in this context as "clients") which may or may not be running on the same computer. |
| World Wide Web | is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them via hyperlinks. |
| Network packet | formatted unit of data carried by a packet mode computer network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links |
| Telephone line | a single-user circuit on a telephone communication system. Typically this refers to the physical wire or other signaling medium connecting the user's telephone apparatus to the telecommunications network, and usually also implies a single telephone number for billing purposes reserved for that user. |
| Internet | global system of interconnecting computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. |
| Hyperlink | a reference to a document that the reader can directly follow, or that is followed automatically |
| DARPA | Defense Advanced Research Projects Agency an agency of the United States Department of Defense responsible for the development of new technology for use by the military. DARPA has been responsible for funding the development of many technologies which have had a major effect on the world, including computer networking, as well as NLS, which was both the first hypertext system, and an important precursor to the contemporary ubiquitous graphical user interface. |
| ARPANET | was the world's first operational packet switching network and the core network of a set that came to compose the global Internet. The network was funded by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense |
