INF file (Information File)
Information (INF) files store information in a specific format. The set-up functions retrieve
information from the INF file to use when performing installation operations. Examples of the type of
information stored in an INF file include INI and registry changes, file names, and locations of the
source files on source media.
Interlaced/non-interlaced
Interlaced.
The method of writing a picture on the screen by initially writing all even lines and subsequently
writing all odd lines of the picture. Result: The complete picture is composed of two interlaced half
pictures (or fields). With interlacing, a vertical (or field) frequency of 50 Hz means a picture (or
frame) frequency of 25 Hz.
Non-interlaced.
The method of writing a picture on the screen by successive video lines of the picture so that a full
frame is written onto the screen in one vertical sweep of the beams. With a non-interlaced display, a
vertical frequency of 50 Hz means a picture (or frame) frequency of 50 Hz. At any given resolution,
non-interlaced modes are preferable to interlaced modes; however, generation of non-interlaced
modes is more expensive.
