The idealized office in which paper is absent because all information is stored and transferred electronically. With the ever-expanding application of computers into business areas as diverse as accounting, desktop publishing, billing, mail, and scheduling, it seemed in the early 80s that the real paperless office was just around the corner. Ironically, just the opposite has transpired. The ease with which computers enable people to print all sorts of documents has created a flood of new paper. Indeed, perhaps the most widespread computer application is the fax machine, which uses paper by the ream.
Some analysts believe that the paperless office is still an achievable and laudable goal, but that certain key technologies such as optical character recognition (OCR) must be improved. Others, however, argue that the tangibleness of paper documents yields certain benefits that will never disappear.
In digital video and film terminology parabolic is a type of microphone that is used to record sounds from a great distance.
In digital photography, parallax is the term used to describe the difference between the image as seen by a viewing system and the image as recorded by the sensor. Variance occurs as subjects move closer to the lens. Only through the lens viewing systems avoid parallax error. See “A Quick Guide to Digital Cameras” in […]
Refers to processes that occur simultaneously. Printers and other devices are said to be either parallel or serial. Parallel means the device is capable of receiving more than one bit at a time (that is, it receives several bits in parallel). Most modern printers are parallel.
- parallel interface
A channel capable of transferring more than one bit simultaneously. Almost all personal computers come with at least one parallel interface. The other type of interface is a serial interfaces.
- Parallel Port
A parallel interface for connecting an external device such as a printer. Most personal computers have both a parallel port and at least one serial port. On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth. It is often […]
