HDMI.
HDMI ports accept connections from HDMI cables, which transmit and receive high-definition audio and visual signals. RCA. USB-A. USB-B. USB-C. USB 3.0. 3.5mm audio. Ethernet.- Port security is what can help secure the network by making sure to block foreign devices from forwarding packets.
With the use of port security, users can restrict the number of MAC addresses that can be learned to a port, configure static MAC addresses, and impose penalties on unauthorized users that use the port.
