Short for plain old telephone service, which refers to the standard telephone service that most homes use. In contrast, telephone services based on high-speed, digital communications lines, such as ISDN and FDDI, are not POTS. The main distinctions between POTS and non-POTS services are speed and bandwidth. POTS is generally restricted to about 52 Kbps (52,000 bitsper second).
The POTS network is also called the public switched telephone network (PSTN).
POTS should not be confused with pot, an abbreviation of potentiometer.

The physical server and single instance of the operating system is virtualized into multiple isolated partitions, where each partition replicates a real server. The OS kernel will run a single operating system and provide that operating system functionality […]
Short for Plastic Pin Grid Array. PPGAs were first developed by Intel in 1993 to combat power supply decoupling issues in high-performance microprocessors.This square chip packaging technology was designed for microprocessors with greater numbers of transistors on each chip than previous models. Unlike ceramic pin grid arrays (CPGA) or tape carrier packages (TCP), PPGA packages […]
Short for Point-to-Point Protocol, a method of connecting a computer to the Internet. PPP is more stable than the older SLIP protocol and provides error checking features. Working in the data link layer of the OSI model, PPP sends the computer’s TCP/IP packets to a server that puts them onto the Internet.
Short for Point-to-Point Protocol over Asynchronous Transfer Mode (ATM). PPPoA relies on two widely accepted standards: PPP and ATM. It is an end-to-end asymmetric digital subscriber line (ADSL) architecture. IP packets travel from the PC over Ethernet to the DSL modem, called the ADSL transceiver unit-remote (ATU-R). The ATU-R adds the PPP protocol to the […]
