Raster (addressable, modifiable pixels) devices attached to computers as
output devices.

The libraries to access them are non-standard, so the standard has no need
to mention such a thing.

Your sarcasm detector is broken. It seems exceptionally likely that
Dag-Erling knew this.

Screen is a full-screen window manager that multiplexes a
physical terminal between several processes (typically
interactive shells). Each virtual terminal provides the
functions of a DEC VT100 terminal and, in addition, sev-
eral control functions from the ISO 6429 (ECMA 48, ANSI
X3.64) and ISO 2022 standards (e.g. insert/delete line and
support for multiple character sets). There is a scroll*-
back history buffer for each virtual terminal and a copy-
and-paste mechanism that allows moving text regions
between windows.

(From the man page.)
