`_ “In”. device. rernote computing cyc—
`‘x'.m..—']‘he exchange device controls
`the flow of information between the
`computer and the terminals. Characters
`[wed at the terminals are sent to the
`computer one line at a tune vta the ex-
`change device. The computer returns
`ah answer
`to the exchan e device.
`which, in turn. sends It to t_e proper
`terminal.
`_1 he exchan e device allows
`each terminal to sen
`or receive data
`independent of all other terminals.

`ing-
`"flhgnge instruction—An instruction to
`replace the contents of one register (or
`set of registers) With the contents ol'an-
`other and vice versa.
`
`exchonge, monUoI—An exchange where
`calls are routed by an operator.
`.xchonge, message — A device placed be-
`tween :1 communication line and a com-
`puter in order to take care of certain
`communication functions and thereby
`free the computer for other work.

`NOR.
`
`exclusive OR — A Boolean lo ic operation
`performed between 5 eci ed registers
`on a bu-by-btt basis.
`'
`lo ic one is left
`in the results register ifeit ter bit in any
`bit position of either register is a one. A
`logic zero is left if both are a logic one
`or both are a logic zero.
`exclusive OR function — A lo ic operation
`in which the result is logica ly true when
`only one inpttl function is true. and false
`when both inputs are true or false.
`exclusive OR, logical—Smite as gate. ex-
`clusuve OR.
`
`exclusive segments—See segments. ex-

`
`
`execute cycle -~ The portion of the opera-
`tional sequence ofa computer when the
`actions required to perform an instruc-
`tion are actually accomplished. Occurs
`after a "fetch" cycle has obtained an in-
`struction from memory.
`execute phose — l. The part of the com-
`
`puter operating cycle wherein a com-
`mand in the program register is carried
`out u on the address indicated. ‘2. The
`
`act 0 performing a command.
`execution -— The processes which are per-
`formed by computer devices and cir-
`cuitry which accomplish a particular in-
`struction or design.
`
`execution cycle—That portion of a ma-
`chine cycle during which the actual exe-
`cution of the instruction takes
`lace.
`Some operations (e.g.. divide. mu tiply}
`may need a large number ol‘these oper-
`ation cycles to complete the operation.
`and the normal
`instruction/operation
`alternation will be held up during this
`time. Also called operation cycle.
`execution-error
`detection — Detection
`concerned with those errors detected
`
`during the execution ol'the user's pro-
`gram. 'l‘hey include errors that are de-
`teclable only during program execution
`(e.g.. invalid subscript value. reference
`to an undefined variable. arithmetic
`spills. etc.) along with those errors of
`completeness detected because either
`(1) they were disregarded by the user
`when previously detected or (2)
`they
`were not detected in the first place be-
`cause the user did not indicate that his
`
`program was completed.

`Computer to produce the result spe-
