Short for "standard play"--the highest possible quality speed for standard VHS, offering two hours of recording on a standard videocassette. (Of course, for VHS, this isn't saying much.) As opposed to EP/SLP and LP speeds.

The trademarked name for a line of supercomputers from IBM. These impressive machines are built out of many SMP servers (2-way to 8-way depending on the model) linked together by a high speed, proprietary communication interface (the so called SP switch) to create a large distributed memory parallel computer. You will find a large population of SP's on the Top500 supercomputer listing: http://www.top500.org/
