True Type Font (TTF)
The invention of movable type by Johann Gutenberg brought about a revolution
in printing by making economical text reproduction possible for the first time.
Since the beginning of the DTP boom, print has again been undergoing a
revolution that has been shaped significantly by True Type technology and
PostScript Type 1 fonts. Both font technologies are not described in the form of
dot patterns, but by means of vectors, which makes it possible to scale them
without a loss in quality. The file extension for these fonts is .ttf.
Virtual memory
Also called disk swapping. The temporary relocation of currently unneeded data
from main memory to the hard disk. This is a mechanism to effectively increase
the amount of available main memory.
