What is a parallel port in a computer?
(1) A hardware interface that transfers one or more bytes simultaneously. See parallel interface. (2) A socket on a computer used to connect a printer or other device via a parallel interface (eight data bits transferring simultaneously).
What are types of parallel ports?
Parallel port modes The computer is capable of having the parallel port run at different modes depending on your needs and available resources. Some of these modes include: IEEE-1284 (Auto), Centronics mode, Nibble Mode, SPP (unidirectional), bidirectional, EPP, and ECP.
How many ports my computer has?
You can have a total of 65,535 TCP Ports and another 65,535 UDP ports. When a program on your computer sends or receives data over the Internet it sends that data to an ip address and a specific port on the remote computer, and receives the data on a usually random port on its own computer.
What is the use of 25 pin parallel port?
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.
