What are parallel port in a computer?
In computing, a parallel port was a type of interface found on computers (personal and otherwise) for connecting peripherals. The name refers to the way the data is sent; parallel ports send multiple bits of data at once (parallel communication), as opposed to serial communication, in which bits are sent one at a time.
What is parallel port and purpose it?
A parallel port is an interface allowing a personal computer (PC) to transmit or receive data down multiple bundled cables to a peripheral device such as a printer. The most common parallel port is a printer port known as the Centronics port.
Where is parallel port on computer?
The parallel port is found on the back of the computer and is part of the motherboard. Below is an example of the DB25 interface found on the back of the computer. With the introduction of USB, FireWire, and other faster solutions, parallel ports are rarely used anymore.
Where are parallel port used?
On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth. It is often called a Centronics interface after the company that designed the original standard for parallel communication between a computer and printer.
What is difference between serial port and parallel port?
A serial port is able to transmit a single stream of data at a time. A parallel port is able to transmit multiple data streams at a time. A serial port sends data bit by bit after sending a bit at a time. A parallel port sends data by sending multiple bits in parallel fashion.
How do you use a parallel port?
How Parallel Ports Work
- Pin 1 carries the strobe signal.
- Pins 2 through 9 are used to carry data.
- Pin 10 sends the acknowledge signal from the printer to the computer.
- If the printer is busy, it will charge Pin 11.
- The printer lets the computer know if it is out of paper by sending a charge on Pin 12.
What devices use parallel ports?
A parallel port uses Female ports. Modems, security cameras, device controllers use serial ports. Printers, Hard Drives, CD drives use parallel ports.
What is the advantage of a USB port?
USB allows data to travel on the average of ten times the speed of the normal parallel port. It is also faster than a serial port. The average serial port transfer rate is 150 kbps; the USB port is up to 12 Mbps. USB 2 is forty times faster, with a maximum transfer rate of 480 Mbps.
What is the function of serial port and parallel port in PC?
A serial port is able to transmit a single stream of data at a time. A parallel port is able to transmit multiple data streams at a time.
What are the ports of a computer?
A hardware port is a physical connection on a computer or another electronic device. Common ports on modern desktop computers include USB, Thunderbolt, Ethernet, and DisplayPort. Previous generations of computers used different ports, such a serial ports, parallel ports, and VGA ports.
What are the uses of computer ports?
Computer ports have many uses, to connect a monitor, webcam, speakers, or other peripheral devices. On the physical layer, a computer port is a specialized outlet on a piece of equipment to which a plug or cable connects.
What is a parallel port connector?
The parallel port is a 25 pin female connector where the printer cable connects. The ports COM1 and COM2 on your computer are serial ports and the LPT1 port is a parallel port. Each pin has a specific function such as transmit data, receive data, data terminal ready or autofeed.
What is a parallel port printer?
A parallel port is an interface allowing a personal computer (PC) to transmit or receive data down multiple bundled cables to a peripheral device such as a printer. The most common parallel port is a printer port known as the Centronics port.
