Virtual legacy wires

Virtual legacy wires are like pretend wires that allow old computer programs or devices to talk to newer computers or devices. It's like when you play with your toy phone and pretend to talk to someone on the other end. The new device may not have the same physical connections as the old device, but the virtual legacy wire creates a way for them to communicate and work together. It's an important tool for keeping old programs and devices working even as technology continues to change and improve.
