parallel interface

A computer connects to a printer via a parallel interface cable.

Definition
  1. Noun:
    • A type of computer hardware connection: A "parallel interface" is a specific method for connecting a computer to an external device, most commonly a printer. Its defining characteristic is that it transmits multiple bits of data (typically 8 bits, or one byte) simultaneously across separate wires within the cable. This contrasts with a serial interface, which sends bits one after another on a single wire.
Usage
  • The term "parallel interface" is used to specify the type of port, cable, and communication standard. It is often mentioned when discussing older computer hardware, printer connections, or data transfer methods.
  • It functions as a compound noun. The adjective "parallel" describes the nature of the "interface."
Examples
  • Noun:
    • The old dot-matrix printer was connected to the computer via a parallel interface.
    • Before USB became standard, most printers used a parallel interface.
    • You need a special cable for a parallel interface; a serial cable won't work.
Advanced Usage
  • "Centronics interface": This is a common, specific type of parallel interface historically used for printers. The terms are often used interchangeably in casual reference.
    • The printer supports the Centronics parallel interface.
Variants and Related Words
  • Parallel port (n): The physical connector on a computer designed for a parallel interface cable.
    • The computer has two serial ports and one parallel port.
  • IEEE 1284 (n): The technical standard that defines the modern implementation of the parallel port for bidirectional communication.
  • LPT port (n): The common name for a parallel port in DOS and Windows systems (e.g., LPT1, LPT2).
Synonyms
  • Parallel port: Often used synonymously, though technically the port is the connector, and the interface is the communication method.
  • Printer port: A common informal term, as parallel interfaces were predominantly used for printers.
Antonyms / Contrasting Terms
  • Serial interface: An interface that transmits data one bit at a time sequentially.
  • USB (Universal Serial Bus): A modern, high-speed serial interface standard that has largely replaced parallel interfaces for printer connections.
