A user is setting up an older model barcode scanner that connects via a serial port to a modern computer that lacks a native serial interface. What device should the IT support technician recommend to facilitate the connection?
Correct Answer: A
Correct Answer. A. Serial to USB adapter A serial to USB adapter is the appropriate solution for connecting a device that uses a serial port to a modern computer that only has USB ports. This adapter will convert the serial signal to USB, allowing the older hardware to communicate with the newer system. Option B is incorrect because a serial to Ethernet adapter is generally used for network connectivity purposes and not suitable for direct device interface like barcode scanners. Option C is incorrect because serial to HDMI adapters do not exist; HDMI is a video interface standard that is unrelated to serial communications. Option D is incorrect because VGA is a video output interface and does not support serial data transfer.
