A process developed by IBM in which client requests over the Internet can be routed to the cell that is geographically closest. When one or more mirror sites exists, ping triangulation uses a process called echo location. When a server receives a client request, it sends out an ICMP echo, or ping, packet across the Internet to the mirror sites and times the echo response. From this information, the most appropriate site to respond to the client request is determined. Basically, ping triangulation maps in multidimensional space the location of every mirror site and the end-user, sending that user not only to an open server but to the closest open server.

)A temporary software connection between two programs or commands. Normally, the operating system accepts input from the keyboard and sends output to the display screen. Sometimes, however, it is useful to use the output from one command as the input for a second command, without passing the data through the keyboard or display screen. Pipes […]
- pipeline burst cache
A type of memory cache built into many modern DRAM controller and chipset designs. Pipeline burst caches use two techniques – a burst mode that pre-fetches memory contents before they are requested, and pipelining so that one memory value can be accessed in the cache at the same time that another memory value is accessed […]
(n.) (1) A technique used in advanced microprocessors where the microprocessor begins executing a second instruction before the first has been completed. That is, several instructions are in the pipeline simultaneously, each at a different processing stage. The pipeline is divided into segments and each segment can execute its operation concurrently with the other segments. […]
