operating system-level virtualization
More commonly called OS-level virtualization. A type of server virtualization technology which works at the OS layer. 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 to each of the partitions. Not to be confused with operating system virtualization.
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 […]
Acronym for Point-to-Point Protocol over Ethernet. PPPoE relies on two widely accepted standards: 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 […]
Short for Palm Query Application, a Web clipping application that allows Palm PDA users to interact wirelessly with Web content.
