Networking terms and abbreviations
Internet or IP
telephony
IP or Internet telephony are communications, such as voice, facsimile,
voice-messaging applications, that are transported over the Internet,
rather than the public switched telephone network (PSTN). IP
telephony is the two-way transmission of audio over a packet-switched
IP network (TCP/IP network).
An Internet telephone call has two steps: (1) converting the analog
voice signal to digital format, (2) translating the signal into Internet
protocol (IP) packets for transmission over the Internet. At the
receiving end, the steps are reversed. Over the public Internet, voice
quality varies considerably. Protocols that support Quality of Service
(QoS) are being implemented to improve this.
IP Internet Protocol is the method or protocol by which data is sent from
one computer to another on the Internet. Each computer (host) on the
Internet has at least one IP address that uniquely identifies it. Internet
Protocol specifies the format of packets, also called datagrams, and
the addressing scheme. Most networks combine IP with a higher-level
protocol called Transmission Control Protocol (TCP), which
establishes a virtual connection between a destination and a source.
IPC Interprocess Communication. A capability supported by some
operating systems that allows one process to communicate with
another process. The processes can be running on the same
computer or on different computers connected through a network.
