`
`PLUG AND PLAY a standard way of configuring PC-compatible com-
`putcr hardware automatically. developed by Microsoft and a number of
`other companies in the mid-1990s. Plug and Play hardware is compul-
`ible with conventional hardware (ISA. PCI, PCMCIA, Micro Channel,
`etc.) but has additional capabilities. Each card or accessory inserted
`into a computer contains identifying in1"orina1ion that can be read by
`the BIOS and the operating system. Thus, the computer can see all die
`installed accessories and can configure itself to use them appropriately.
`PLUG-IN an accessory program that provides additional functions for a
`main application program. Plug-ins have to be loaded at the some time
`as the main program; they then show up as an option in an appropriate
`menu.

`FIGURE 169. POINT
` j_..j
`
`POINT a unit of typographical measurement equal to g inch. The height
`of type is usually expressed in points. However, this is not a measure-
`ment of the size of the letters, but rather of die wooden blocks on
`which the metal type was mounted for printing presses. This usually
`included some space at the top of the tallest capital letters and below
`the descenders. Therefore, different typefaces of the same point size
`may actually differ in size. To this day, even digitized typefaces show
`some of die same idiosyncrasies. A desire to be faithful to the original
`designs has prevented the type‘s apparent sire from being regularized.
