- Locality of networks [r]: The assumption, in networking technologies, about the characteristics of the user space they support, and, as importantly, the user spaces they should ignore [e]
- Metcalfe's Law [r]: A controversial way of assessing the economic values that allow pairwise communications, such as the Public Switched Telephone Network, based on the number of users. [e]
- Packet switching [r]: Network communications method that groups all transmitted data, irrespective of content, type, or structure into suitably-sized blocks, called packets. [e]
- Pentagon Building [r]: Headquarters office building of the U.S. Department of Defense, as well as a symbol of the U.S. military [e]

- Unix [r]: A computer operating system originally conceived and developed by a group of researchers as an unofficial project while they were working at AT&T's Bell Laboratories. [e]
- Value of networks [r]: A variety of factors influence the value of communications networks, including the number of participants, the interconnections among the participants, and the reliability of both the physical network and the information it carries. [e]
- Voice Over IP [r]: Add brief definition or description
- Voice over Internet Protocol [r]: A family of standards that permits carrying voice telephony over Internet Protocol networks that handle both voice and data, instead of dedicated telephony networks. [e]
