- optical drive — optical disk drive
- optical fiber — optical fibre
- optical fibre — (communications) (fibre optics, FO, US "fiber", light pipe) A plastic or glass (silicon dioxide) fibre no thicker than a human hair used to transmit information using infra-red or even visible light as the carrier (usually a laser). The light beam is an electromagnetic signal with a frequency in the range of 10^14 to 10^15 Hertz. Optical fibre is less susceptible to external noise than other transmission media, and is cheaper to make than copper wire, but it is much more difficult to connect. Optical fibres are difficult to tamper with (to monitor or inject data in the middle of a connection), making them appropriate for secure communications. The light beams do not escape from the medium because the material used provides total internal reflection. See also FDDI, Optical Carrier n, SONET.
- optical mouse — (hardware) Any kind of mouse that uses visible light or infrared to detect changes in its position.
- optical wedge — a wedge-shaped filter whose transmittance decreases from one end to the other: used as an exposure control device in sensitometry.

- output device — (hardware) Electronic or electromechanical equipment connected to a computer and used to transfer data out of the computer in the form of text, images, sounds or other media to a display screen, printer, loudspeaker or storage device. Most modern storage devices such as disk drives and magnetic tape drives act as both input and output devices, others such as CD-ROM are input only.

- pacific ocean — an ocean bordered by the American continents, Asia, and Australia: largest ocean in the world; divided by the equator into the North Pacific and the South Pacific. 70,000,000 sq. mi. (181,300,000 sq. km); greatest known depth, 35,433 feet (10,800 meters).
- pacific plate — Geology. one of the major tectonic divisions of the earth's crust, comprising four sea-floor basins; separated from the Nazca, Cocos, and North and South American plates by the East Pacific Rise and San Andreas fault and bounded in the western Pacific Ocean by a series of major ocean deeps, including the Kuril, Japan, Mariana, Kermadec, and Tonga trenches.
- packet driver — (networking) IBM PC local area network software that divides data into packets which it routes to the network. It also handles incoming data, reassembling the packets so that application programs can read the data as a continuous stream. Packet drivers provide a simple, common programming interface that allows multiple applications to share a network interface at the data link layer. Packet drivers demultiplex incoming packets among the applications by using the network media's standard packet type or service access point field(s). The packet driver provides calls to initiate access to a specific packet type, to end access to it, to send a packet, to get statistics on the network interface and to get information about the interface. Protocol implementations that use the packet driver can coexist and can make use of one another's services, whereas multiple applications which do not use the driver do not coexist on one machine properly. Through use of the packet driver, a user could run TCP/IP, XNS and a proprietary protocol implementation such as DECnet, Banyan's, LifeNet's, Novell's or 3Com's without the difficulties associated with pre-empting the network interface. Applications which use the packet driver can also run on new network hardware of the same class without being modified; only a new packet driver need be supplied. There are several levels of packet driver. The first is the basic packet driver, which provides minimal functionality but should be simple to implement and which uses very few host resources. The basic driver provides operations to broadcast and receive packets. The second driver is the extended packet driver, which is a superset of the basic driver. The extended driver supports less commonly used functions of the network interface such as multicast, and also gathers statistics on use of the interface and makes these available to the application. The third level, the high-performance functions, support performance improvements and tuning.
