A networking protocol developed for the creation of a robust internet being a connection across a variety of local networking mechanisms. The protocol used to connect to and through what is known today as the internet. The internet uses a layered architecture with several protocols. The TCP (Transmission Control Protocol) defines session-based communications, and the IP (Internet Protocol) addresses the lower-level issues of packet fragmentation and routing
Conditioned air is supplied to the inlets of the rack/cabinet for convective cooling of the heat rejected by the components of the electronic equipment within the rack. It is understood that within the rack, the transport of heat from the actual source component (e.g., CPU) within the rack itself can be either liquid- or air-based, but the heat rejection media from the rack to the terminal cooling device outside of the rack is air
The system being tested, as distinct from anything in the testbed being used to drive the test
Within IEEE 802.3, the total number of symbols per second transferred to or from the medium dependent interface (MDI) on a single wire pair. For 100BASE-T4, the symbol rate is 25 MBd. For 100BASE-X, the symbol rate is 125 MBd. For 100BASE-T2, the symbol rate is 25 MBd. For 1000BASE-T, the symbol rate is 125 MBd
Combination of electrical disconnects and/or circuit breakers meant to isolate equipment in or near an electrical substation
