• clocks n. Processor logic cycles, so called because each generally corresponds to one clock pulse in the processor's timing.
  The relative execution times of instructions on a machine are usually discussed in clocks rather than absolute fractions of a second...
• cycle: 1. n. The basic unit of computation. What every hacker wants more of (noted hacker Bill Gosper describes himself as a "cycle junkie").
  One can describe an instruction as taking so many `clock cycles'....

• bit bang: n. Transmission of data on a serial line, when accomplished by rapidly tweaking a single output bit, in software, at the appropriate times.
  The technique is a simple loop with eight OUT and SHIFT instruction pairs for each byte....
• wall time: n. (also `wall clock time') 1. `Real world' time (what the clock on the wall shows), as opposed to the system clock's idea of time.
  2. The real running time of a program, as opposed to the number of {tick}s required to execute it (on a timesharing system these always differ, as no one program gets all the ticks, and on multiprocessor systems with good thread support one may get more processor time than real time)....

• PDP-10: [Programmed Data Processor model 10] n. The machine that made timesharing real.
  It looms large in hacker folklore because of its adoption in the mid-1970s by many university computing facilities and research labs, including the MIT AI Lab, Stanford, and CMU....
