| Post Office Protocol. This is a common protocol used for sending, receiving, and |

|
| Port |
| An Internet port refers to a number that is part of a URL, appearing after a colon (:), |
|
|
|
| directly following the domain name. Every service on an Internet server listens on a |
|
|
|
| particular port number on that server. Most services have standard port numbers, for |
|
|
|
| instance, Web servers normally listen on port 80. |

|
| Port (H/W) |
| An interface on a computer for connecting peripherals or devices to the computer. A |
|
|
|
| printer port, for example, is an interface that is designed to have a printer connected to |
|
|
|
| it. Ports can be defined by specific hardware (such as a keyboard port) or through |
|
|
|
| software. |

| POTS |
| Plain Old Telephone Service is the analog telephone service that runs over copper |
|
|
|
|
| |
|
|
| wires connect homes and businesses to a neighborhood central office. This is called the |
|
|
|
| local loop. The central office is connected to other central offices and |
|
|
|
| facilities. |

| PPP |
| Point to Point Protocol. PPP encapsulates and transmits IP (Internet Protocol) |
|
|
|
| datagrams over serial |
|
|
|
| (Internetwork Packet Exchange). The protocol is defined in IETF (Internet Engineering |
|
|
|
| Task Force) RFC 1661 through 1663. PPP provides |

| PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to |
|
|
|
| the Internet through a common broadband medium, such as a single DSL line, wireless |
|
|
|
| device or cable modem. All the users over the Ethernet share a common connection, so |
|
|
|
| the Ethernet principles supporting multiple users in a LAN combine with the principles |
|
|
|
| of PPP, which apply to serial connections. From authentication, accounting and secure |
|
|
|
| access to configuration management, PPPoE supports a broad range of existing |
|
|
|
| applications and services. |

| PPTP |
|
| |
| Protocol |
| A "language" for communicating on a network. Protocols are sets of standards or rules |
|
|
|
| used to define, format and transmit data across a network. There are many different |
|
protocols used on networks. For example, most web pages are transmitted using the HTTP protocol.
