screen saver
<tool> A program which displays either a completely black
image or a constantly changing image on a computer monitor to
prevent a stationary image from "burning" into the phosphor of
the screen. Screen savers usually start automatically after
the computer has had no user input for a preset time. Some
screen savers come with many different modules, each giving a
different effect.
Approximately pre-1990, many cathode ray tubes, in TVs,
computer monitors or elsewhere, were prone to "burn-in";
that is, if the same pattern (e.g., the WordPerfect status
line; the Pong score readout; or a TV channel-number
display) were shown at the same position on the screen for
very long periods of time, the phosphor on the screen would
"fatigue" and that part of the screen would seem greyed out,
even when the CRT was off.
Eventually CRTs were developed which were resistant to burn-in
(and which sometimes went into sleep mode after a period of
inactivity); but in the meantime, solutions were developed:
home video game systems of the era (e.g., Atari 2600s) would,
when not being played, change the screen every few seconds, to
avoid burn-in; and computer screen saver programs were
developed.
The first screen savers were simple screen blankers - they
just set the screen to all black, but, in the best case of
creeping featurism ever recorded, these tiny (often under 1K
long) programs grew without regard to efficiency or even basic
usefulness. At first, small, innocuous display hacks
(generally on an almost-black screen) were added. Later, more
complex effects appeared, including animations (often with
sound effects!) of arbitrary length and complexity.
Along the way, avoiding repetitive patterns and burn-in was
completely forgotten and "screen savers" such as Pointcast
were developed, which make no claim to save your monitor, but
are simply bloated browsers for push media which
self-start after the machine has been inactive for a few
minutes.

screen scraper
<tool> A piece of software used to automate interaction
between two computer systems through the terminal interface
(designed for human use) of one of those systems.
Typically, the screen scraper interacts with terminal
emulation software to generate input to and process output
from the "host" system through terminal screens. Screen
scrapers are advantageous when modifications to the host
system are undesireable, when it is desireable to make use of
the existing business and data integrity logic on the host,
and when no other (peer-to-peer) interface method is
available.
Some products employ screen scraping combined with additional
functionality which provides a DBMS-like or other
specialised interface to the host. The host system is often
called a "legacy system" because it usually the older of the
systems involved and based on older technology.
