From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   d8Pathopd2la \[d8]Path`o*p[d2]"la\, n.; pl. {-ias}. [NL., from
      Gr. [?]; [?] passion + [?] to make.] (Rhet.)
      A speech, or figure of speech, designed to move the passion.

From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
      1. The first modern computer.   It had main
      {registers}, processing circuits, information paths within the
      {central processing unit}, and used {Von Neumann}'s
      {fetch-execute cycle}.
      The IAS machine's basic unit of information was a 40-bit
      {word} and the memory had 4096 words.   A word stored in memory
      could represent either an instruction or data.   Each IAS
      instruction was twenty bits long, so that two instructions
      could be stored in each 40-bit memory location.   Each
      instruction consisted of an 8-bit {operation code} and a
      12-bit address that could identify any of 2^12 locations that
      may be used to store an {operand} of the instruction.
      The {CPU} consisted of a data processing unit and a program
      control unit.   It contained various processing and control
      circuits along with a set of high-speed {registers} for the
      temporary storage of instructions, memory addresses, and data.
      The main actions specified by instructions were performed by
      the arithmetic-logic circuits of the data processing unit.   An
      electronic clock circuit was used to generate the signals
      needed to synchronise the operation of the different parts of
      the system.
      [Who?   Where?   When?   Implemented using what?]
      2. {Immediate Access Storage}.
