What will happen if you connect a 10BaseT NIC to an auto-sensing switch?

If you connect a 10BaseT NIC to an auto-sensing switch, the switch will automatically detect the NIC's speed and configure the port to operate at 10 Mbps. The connection will function correctly, allowing communication between devices at the lower 10BaseT speed, while other ports on the switch can operate at higher speeds (like 100BaseT) if connected to compatible devices. This ensures compatibility and seamless integration within a mixed-speed network environment.
