- 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.

- process table — (operating system, process) A table containing all of the information that must be saved when the CPU switches from running one process to another in a multitasking system. The information in the process table allows the suspended process to be restarted at a later time as if it had never been stopped. Every process has an entry in the table. These entries are known as process control blocks and contain the following information: process state - information needed so that the process can be loaded into memory and run, such as the program counter, the stack pointer, and the values of registers. memory state - details of the memory allocation such as pointers to the various memory areas used by the program resource state - information regarding the status of files being used by the process such as user ID. Accounting and scheduling information. An example of a UNIX process table is shown below. SLOT ST PID PGRP UID PRI CPU EVENT NAME FLAGS 0 s 0 0 0 95 0 runout sched load sys 1 s 1 0 0 66 1 u init load 2 s 2 0 0 95 0 10bbdc vhand load sys SLOT is the entry number of the process. ST shows whether the process is paused or sleeping (s), ready to run (r), or running on a CPU (o). PID is the process ID. PGRP is the process Group. UID is the user ID. PRI is the priority of the process from 127 (highest) to 0 (lowest). EVENT is the event on which a process is paused or sleeping. NAME is the name of the process. FLAGS are the process flags. A process that has died but still has an entry in the process table is called a zombie process.
