What is a Serial Port?

A serial port is an Interface that lets in a PC to transmit or receive Records one bit at a time. It is one of the oldest Forms of interfaces and at one time became commonly used to attach printers and External Modems to a PC. Modern serial ports are used in clinical contraptions, save until sySTEMs along with cash registers and applications like industrial machinery structures.

Compared to a Parallel Port, the information Transfer Rate of a serial port is slower.

What Does Serial Port Mean?

Normally, a serial port is a male port, even as a parallel port is a female port. System useful resource Configurations are selected for every port and are recognized via COM1, COM2, COM3, COM4, and so on. Each COM role represents an enter/Output (I/O) and an Interrupt Request (IRQ) deal with. The I/O address transfers and receives statistics to and from a Peripheral Device along with a Mouse or Keyboard.

The serial port wellknown is RS-232. This fashionable is used for transmitting Serial Communication between Devices, which are normally referred to as records Communications System (DCE) and Data Terminal Equipment (DTE). The serial port Makes use of a 9-pin (DE-9) connector or a 25-pin (DB-25) connector. Originally, the standard used 25 pins. Because a few of the pins were unused and had been pretty cumbersome, the smaller DE-nine connector became famous.

Higher pace communique became needed for serial communication, including external statistics garage gadgets. In 1998, the Universal Serial Bus (USB) and FireWire introduced faster interfaces. This new era may want to transfer statistics at high costs on the identical Bus, called a Daisy Chain.

Today, the serial port is seldom used but may be located as a verbal excHange device for GPS Receivers, LED and LCD textual content shows, bar-Code Scanners and flat-screen Monitors.
