PoP stands for Point of Presence or Post Office Protocol. This is the point at which most devices share a common connection and can communicate with each other. At this point, a company's public network ends and the customer's private network begins. For this reason, a PoP is also called an artificial demarcation point.
A POP consists of high-speed telecommunication devices and technologies. It is a protocol that allows you to communicate over the Internet with people all over the world. E-mail clients on a network usually use this type of protocol to retrieve e-mail from the mail server.
This protocol works together with TCP/IP and enables fast communication between devices on the network. To ensure that the Internet connection is not interrupted, the user must be connected to the private network provided by the Internet service provider. If you want to send and receive e-mails from your home computer, you need to connect to the public Internet through a router or a modem.
