serial port
Noun: A serial port is a type of computer interface. It is a physical connection point on a computer or device designed for serial communication. This means it transmits data one bit at a time over a single communication channel or wire. Historically, it was a common standard interface for connecting peripherals like modems, computer mice, and some printers.
The term "serial port" is used to refer to the specific hardware connector and its associated communication protocol. It is typically a countable noun. * Early personal computers usually had one or two serial ports for connecting external devices. * To configure the modem, you need to specify which serial port it is connected to. * Many industrial machines still use a serial port for data transfer due to its simplicity and reliability.
- "The technician connected the diagnostic cable to the serial port on the back of the router."
- "This software requires a device, such as an old GPS unit, that communicates via a serial port."
- "Most modern laptops no longer include a built-in serial port, so you need a USB-to-serial adapter."
- Legacy Technology: In contemporary computing, the physical serial port is largely considered legacy technology, having been superseded by USB (Universal Serial Bus). However, the underlying concept of serial communication remains fundamental and is widely used in electronics, embedded systems, and industrial controls (often via protocols like RS-232, RS-485, or TTL serial).
- Virtual Serial Port: Software can create a virtual serial port, which behaves like a physical port but sends data over a network or between applications.
- COM port: A common name for a serial port on Windows-based systems (short for Communication port), e.g., COM1, COM2.
- RS-232 port: A specific and very common technical standard for serial communication, often used synonymously with "serial port."
- Parallel port: A contrasting type of interface that transmits multiple bits of data simultaneously over several wires.
- Communication port (COM port)
- RS-232 port (in specific technical contexts)
- Async port (asynchronous port)
- Serial communication: The general method of data transfer used by a serial port.
- Serial cable: The cable used to connect devices to a serial port.
- Configure the serial port: To set parameters like baud rate, data bits, and parity for the port's operation.
- an interface (commonly used for modems and mice and some printers) that transmits data a bit at a time
