read-eval-print loop definition
<language, LISP, programming> (REPL) A programming structure
within LISP which repeatedly reads a form from the user,
evaluates it, and displays the result.
A read-eval-print loop forms the basis of the Top-Level
shell that programmers of the LISP family of languages
interact with.
In many dialects of LISP a very simple REPL could be
implemented as:
(loop (print (eval (read)))).

README file definition
<convention> An introduction traditionally included in the
top-level directory of a Unix source distribution,
containing a pointer to more detailed documentation, credits,
miscellaneous revision history, notes, etc. The file may be
named README, or READ.ME, or rarely ReadMe or readme.txt or
some other variant.
In the Macintosh and IBM PC worlds, software is not
usually distributed in source form, and the README is more
likely to contain user-oriented material like last-minute
documentation changes, error workarounds, and restrictions.
The README convention probably follows the famous scene in
Lewis Carroll's "Alice's Adventures In Wonderland" in which
Alice confronts magic munchies labelled "Eat Me" and "Drink
Me".

Read-Only Memory definition
<storage> (ROM) A type of data storage device which is
manufactured with fixed contents. In its most general sense,
the term might be used for any storage system whose contents
cannot be altered, such as a gramophone record or a printed
book; however, the term is most often applied to
semiconductor integrated circuit memories, of which there
are several types, and CD-ROM.
ROM is inherently non-volatile storage - it retains its
contents even when the power is switched off, in contrast to
RAM.
ROM is often used to hold programs for embedded systems
since these usually have a fixed purpose. ROM is also used
for storage of the lowest level bootstrap software
(firmware) in a computer.

<jargon> Describes a luser who uses computers almost

useful information.
