The port which is a protocol for transferring data to and from digital devices is known as:

This question was previously asked in

RRB NTPC 2019 CBT 1 Question Paper PDF (31-Jan-2021) (Shift 1)

VGA monitor port

USB port

Parallel port

PS/2 ports

The correct answer is

USB port

USB port is correct.

USB stands for Universal Serial Bus. It is an industry standard that defines the cables, connectors and communication protocol used to transfer data (and supply power) between a computer and digital devices such as pen drives, printers, cameras and phones.

A VGA port only carries analogue video to a monitor, a parallel port is an older printer interface, and PS/2 ports connect only a keyboard or mouse, so none of them is the general data-transfer protocol described.
