The 4 octets in an IP address are divided into _________ & ___________.
What is Network ID & HOST ID For example, if I had an IP address of 192.168.1.15 and a subnet mask of 255.255.255.0, the first three octets would make up the network ID and the last octet would be the host ID> The network ID assigns a unique aaaress to the network itself, while the host ID uniquely identifies the system on the network.

______________ is the IP address of the router that can send data from your network
What is Default Gateway when your system wants to send data to another system on the network, it looks at its own network ID and compares that with the destination system’s IP address. If they have the same network ID, the data is sent directly from your system to the destination system. If the two systems are on different networks your system must pass the data to the router so that the router can send the data to the destinations system’s router.
