192.168.1.95 is PCA's IP Address and 192.168.1.254 is the router's ethernet interface IP.
PCA sends an ARP broadcast request for 192.168.1.254 which is flooded out every switch port. The router receives the ARP request and replies with its MAC address. PCA then adds the ARP entry (IP to MAC mapping) to its ARP table. PCA can then communicate with 192.168.1.254 without having to send further ARP requests until the entry ages out.
