batch processing
A system that takes a set (a "batch") of
commands or jobs, executes them and returns the results, all
without human intervention. This contrasts with an
{interactive} system where the user's commands and the
computer's responses are interleaved during a single run.
A batch system typically takes its commands from a disk file
(or a set of {punched cards} or {magnetic tape} in the old
days) and returns the results to a file (or prints them).
Often there is a queue of jobs which the system processes as
resources become available.
Since the advent of the {personal computer}, the term "batch"
has come to mean automating frequently performed tasks that
would otherwise be done interactively by storing those
commands in a "{batch file}" or "{script}". Usually this file
is read by some kind of {command interpreter} but batch
processing is sometimes used with GUI-based applications that
define script equivalents for menu selections and other mouse
actions. Such a recorded sequence of GUI actions is sometimes
called a "{macro}". This may only exist in memory and may not
be saved to disk whereas a batch normally implies something
stored on disk.
