=Telephone systems=

In the USA, this term became important during the Modification of Final Judgment. A point of presence was a location where a long-distance carrier could terminate services and provide connections into a local telephone network.

=Internet=

An Internet point of presence is an access point to the Internet. It is a physical location that houses servers, routers, ATM switches and digital/analog call aggregators. It may be either part of the facilities of a telecommunications provider that the Internet service provider (ISP) rents or a location separate from the telecommunications provider. ISPs typically have multiple POPs, sometimes in the thousands. POPs are also located in Internet exchange points and colocation centres.

Sometimes the term is used for an internet cafe in a franchising chain.
