optical character recognition (OCR) software OCR software converts an electronic image of text, such as
a scanned document, into a form that word processor, spreadsheet, and database programs can use.

result in a higher resolution, more visible detail in the image, and a larger file size.

used by extensions to place incoming or outgoing calls. Normally, the equipment is owned by the customer
rather than leased from the telephone company.
public switched telephone network (PSTN) The worldwide dial-up telephone network or a portion of that

services carried over a path initially established using normal telephone signaling and ordinary switched long-
distance telephone circuits.
