parallel port
Học thuậtThân thiện
Definition
Noun: - A type of computer interface: A parallel port is a hardware interface on a computer designed primarily for connecting a printer or other peripheral device. It transmits multiple bits of data (typically 8 bits, or one byte) simultaneously over separate wires, in parallel.
Usage
The term "parallel port" is used to specify a particular, largely legacy, type of physical connection on a computer. - It is often contrasted with a serial port, which sends data one bit at a time. - It is commonly associated with the Centronics interface standard for printers.
Examples
- Noun:
- The old dot-matrix printer must be connected to the computer's parallel port.
- Most modern laptops no longer include a parallel port, as USB has become the standard.
Advanced Usage
- Technical Context: In technical specifications, you might see references to the specific implementation, such as the IEEE 1284 standard, which defines the bidirectional version of the parallel port.
- The scanner requires a bidirectional parallel port compliant with IEEE 1284.
Variants and Related Words
- LPT port: An alternative name, especially in Windows operating systems, where parallel ports were designated as LPT1, LPT2, etc. (Line Print Terminal).
- Printer port: A common synonym, as the parallel port was the dominant interface for printers for many years.
- Centronics interface: Refers to the specific connector and protocol originally developed by the Centronics company for their printers.
Synonyms
- Printer port
- LPT port
Antonyms / Contrasting Terms
- Serial port: An interface that transmits data one bit at a time sequentially over a single communication line.
- USB port (Universal Serial Bus): The modern, high-speed serial interface that has largely replaced parallel ports.
Noun
- an interface between a computer and a printer where the computer sends multiple bits of information to the printer simultaneously
