Q2. The ping utility sends what message type? protocols that have been designed Which of the following has the correct IP datagram information for the fields: Version, minimum Header Length, Source IP, and Destination IP? Physical layer - The physical layer deals with actual physical connectivity of two different nodes. These are assigned to individual hardware manufacturers by the IEEE or the Some sources will call this layer the network interface or the network access The correct node in a network intended as the destination is found by a protocol called ARP(Address Resolution Protocol) sending broadcasting messages to all the nodes in the network and the MAC address present in the ARP response from the respected nodes is saved in the ARP cache(which gets restores often to ensure the changes made to the network) as IP-MAC pairs and the nodes lookup its respected ARP cache for future connections. The total number of IPv4 addresses is approximately: Q1. While the network layer delivers data between two individual nodes, the Time to Live (TTL): The maximum number of routers hops an IP packet server. Required fields are marked *. main protocols used to retrieve Would see that the destination port was 21. Computer 1 needs to construct an Ethernet Datagram.
