An IT technician needs to connect a legacy piece of equipment to a modern computer to update its firmware. The equipment only has a serial interface available for the update process. The technician's computer does not have a built-in serial port. Which of the following would BEST solve this problem while ensuring a stable and secure update process?
A USB to serial converter is the correct answer because it allows a modern computer without a serial port to connect to a legacy device that requires a serial interface. USB is a common interface on modern computers, and a converter provides the necessary translation between the USB protocol and the older serial protocol. Other connectors like USB to HDMI or USB to LAN (Ethernet) are not suitable as they don't provide a solution for interfacing with a serial port needed for the legacy device.
