Explanation:

First Question (Fill - in - the - blank)

LAN (Local Area Network) has relatively low transmission cost as it covers a small area (like a building or campus) and is often owned by the organization. WAN (Wide Area Network) covers a large area (like multiple cities or countries) and uses public or shared infrastructure, so its transmission cost is usually higher. So the word to fill in is "transmission cost" related to the difference, specifically the key difference in transmission cost is that WAN has "higher" transmission cost compared to LAN? Wait, no, the sentence is "In addition to geographic distance, the main difference between LANs and WANs is ____ transmission cost." Wait, actually, LANs are typically within a small area, owned by the organization, so their transmission cost per unit is low. WANs use long - distance communication, often relying on third - party providers, so their transmission cost is higher. So the blank should be filled with "transmission cost" in terms of the difference, more precisely, the difference in transmission cost is that WANs have "higher" transmission cost? Wait, no, the structure of the sentence: "the main difference between LANs and WANs is __ transmission cost." So the answer is about the nature of transmission cost. LANs: organizations usually own the infrastructure, so transmission cost is lower (fixed cost, low per - use cost). WANs: use public networks, so transmission cost is higher (variable, based on usage, and often involves fees to service providers). So the blank should be "transmission cost" with the understanding that WANs have higher transmission cost. But the first question is a fill - in - the - blank. Let's re - think: The main difference between LAN and WAN (besides geographic distance) is the transmission cost. LANs have lower transmission cost (since they are in a small area, owned by the organization), WANs have higher transmission cost. So the blank is "transmission cost" in terms of the difference, and the key is that WANs have "higher" transmission cost? Wait, no, the sentence is "the main difference between LANs and WANs is ____ transmission cost." So the answer is "transmission cost" with the characteristic. Wait, maybe the answer is "transmission cost" where LANs have lower and WANs have higher. But the first question's blank: let's see, the correct word is "transmission cost" - the main difference in transmission cost (LAN: low, WAN: high). So the answer for the first blank is "transmission cost" (but more precisely, the difference is in the "transmission cost" level, with WANs having higher transmission cost). But maybe the answer is "transmission cost" as the category, and the key difference is the "transmission cost" (LANs: low - cost, WANs: high - cost). So the first blank should be filled with "transmission cost" (the nature of transmission cost, with WANs having higher transmission cost).

• Option A: local area network (LAN) : Organizations typically own all the components of a LAN. A LAN is a network within a small area (e.g., an office building, a campus), and the organization usually purchases and maintains all the hardware (like switches, routers, cables) and software for the LAN.
• Option B: wide area network (WAN) : A WAN spans a large geographical area (e.g., multiple cities or countries). It often uses public communication infrastructure (like the Internet, leased lines from telecommunication companies). Organizations do not own all the components of a WAN because it involves long - distance communication that relies on third - party service providers (e.g., ISPs, telecommunication companies) for the long - haul transmission components.
• Option C: personal area network (PAN) : A PAN is a network around an individual (e.g., connecting a smartphone, smartwatch, and laptop). It is usually owned and controlled by the individual, and if an organization were to have a PAN, it would be a small, personal - scale network within the organization, and the organization could potentially own all its components.
• Option D: common area network : This is not a standard type of network. The standard network types are LAN, WAN, PAN, MAN (Metropolitan Area Network). So this option is incorrect.

Answer:

transmission cost (more precisely, the answer is related to the difference in transmission cost, with WANs having higher transmission cost, but the blank is to be filled with the relevant term, and the most appropriate is "transmission cost" in the context of the difference, and the key is that WANs have "higher" transmission cost? Wait, no, the sentence structure: "the main difference between LANs and WANs is ______ transmission cost." So the answer is "transmission cost" as the factor, and the actual difference is that WANs have higher transmission cost. But maybe the answer is "transmission cost" with the understanding that the difference is in the transmission cost (LAN: low, WAN: high). So the first answer is "transmission cost" (the key difference is the transmission cost, with WANs having higher transmission cost).
