ISDN (Integrated Services Digital Network)
International standard for switched, digital dial-up telephone service for voice and data. Analog telephones and fax machines are used over ISDN lines, but their signals are converted into digital by the ISDN terminal adapter (see below).

IP (Internet Protocol)
IP uses a packet-switched architecture, in which data are broken up into smaller "packets," with each packet containing a source address and destination address. IP packets are handed over to a data link layer protocol, such as Ethernet, for the actual, physical transmission to the next node in the network path.

Codec - (enCOder/DECoder or COmpressor/DECompressor)
Software or hardware that compresses and decompresses audio and video data streams. The purpose of this type of codec is to reduce the size of digital audio samples and video frames in order to speed up transmission and save storage space

CPU
(Central Processing Unit) The computing part of the computer. Also called the "processor”. Today, the CPUs of almost all computers are contained on a single chip. May be separate computer, may be integrated.
