(computing) (on a computer) a socket that can be used for connecting devices that send and receive data at more than one bit at a time; often used for connecting printers
An interface from a computer system where data is transferred in or out in parallel, that is, on more than one wire. A parallel port carries one bit on each wire thus multiplying the transfer rate obtainable over a single wire. There will usually be some control signals on the port as well to say when data is ready to be sent or received.
The commonest kind of parallel port is a printer port, e.g. a Centronics port which transfers eight bits at a time. Disks are also connected via special parallel ports, e.g. SCSI or IDE.
noun, Geometry. 1. the axiom in Euclidean geometry that only one line can be drawn through a given point so that the line is parallel to a given line that does not contain the point. parallel postulate See under Euclidean.
- Parallel presence detect

- Parallel random-access machine
parallel (PRAM) An idealised parallel processor consisting of P processors, unbounded shared memory, and a common clock. Each processor is a random-access machine (RAM) consisting of R registers, a program counter, and a read-only signature register. Each RAM has an identical program, but the RAMs can branch to different parts of the program. The RAMs […]
