Final answer:
The smallest network is a PAN (Personal Area Network), used for connecting personal devices within close proximity. In broadcast media, a local station distributing national content is known as an affiliate.
Step-by-step explanation:
The smallest network is a PAN (Personal Area Network), which is a network of personal devices, such as the network you use when you sync your mobile phone and your computer. While LANs, MANs, and SANs are all larger networks serving different purposes, the PAN is specifically designed for personal or small space use. It typically involves devices such as computers, phones, tablets, and wearables within a very close range.
In contrast, a local station that broadcasts national network programming is called a(an) affiliate. This is a local broadcaster, often a television or radio station, that has a contractual relationship to distribute content for a larger national or regional network.
