Final answer:
Two protocols that rely on broadcasting are ARP, which maps IP addresses to MAC addresses on a local network, and DHCP, which assigns IP addresses to devices on a network. Governments and organizations utilize broadcasting through radio and television to reach and influence the public.
Step-by-step explanation:
Two protocols that rely on broadcasting are the Address Resolution Protocol (ARP) and the Dynamic Host Configuration Protocol (DHCP). ARP is used to associate the IP addresses of devices on a network with their physical, hardware addresses, known as MAC addresses. When a device wants to communicate with another device on the same local network, it sends out an ARP broadcast to determine the MAC address associated with the IP address it wishes to communicate with. DHCP, on the other hand, is a protocol used for assigning IP addresses to devices on a network. When a device connects to a network, it broadcasts a request for an IP address, and a DHCP server responds with an IP address assignment.
Governments and development organizations use broadcast media to spread information, deliver education, and influence public opinion. Radio and television can be powerful tools for reaching wide audiences, particularly in areas with limited access to the Internet or print media.
