- A popular window system developed by MIT and implemented on
a number of workstations.
- Two work stations used as a COW. One of the stations is used
for display only, the other for a cursor selectable menu (uses
- X-Ray Screen
- A profile monitor off the beam path where x-rays created by
a synchrotron radiation source hit some material to generate
secondary emission of visible light. The light itself is recorded
by a video camera and transmitted by cable to MCC. This type of
beam monitor is used extensively in storage rings where anything
placed in the beam path would kill the stored beam.
- A standard protocol for computer display windows and
graphics developed by MIT and available for most computers.
DECWINDOW is the version for VAXes and microvaxes, MACX is the
version for MACs.

create their own customized tags to provide functionality not
available with HTML. For example, XML supports links that point
to multiple documents, as opposed to HTML links, which can
reference just one destination each.
