Study Notes
Parallel Port Communication
- A parallel port sends data 8 bits (1 byte) at a time to a peripheral device, such as a printer, using multiple wires to transmit multiple bits simultaneously.
- The parallel port uses a 25-pin connector (DB-25) to connect to the peripheral device.
- It operates in a unidirectional manner, meaning data is sent only from the computer to the peripheral device, not the other way around.
- The parallel port uses a parallel communication protocol, where data is transmitted in parallel, allowing for faster data transfer rates compared to serial communication.
- The data is transmitted using a specific protocol, such as the Centronics protocol, which defines the signal lines and their functions.
- The parallel port is often used for printer connections, but can also be used for other devices, such as scanners and_external hard drives.
Parallel Port Communication
- A parallel port communicates information to a peripheral device one byte at a time.
Learn about the parallel port communication protocol, its architecture, and how it sends data to peripheral devices like printers.
