The standard PC parallel port was originally designed for sending information to Printers or Scanners. That is the reason why they are sometimes referred to as Line Printer Terminal (LPT) ports.
They are D-shaped with holes for 25 pins.
It is used mainly to connect Printers, Scanners, and sometimes external Hard drives, CD-ROM drives, Tape devices & Network adapters to your computer.
Parallel ports transmit data using an 8–bit parallel interface & are therefore, used for devices that accept information 8 bits at a time. They transmit data byte-by-byte. They are usually faster than Serial ports.
Note. The SCSI Port is an example of a parallel port.
