For what does WAN stand?

Computer networks are classified by the size of the geographical area they cover. A network confined to one room or building is called a local area network, while a network that spans cities, countries, or even continents needs a different classification.

WAN stands for Wide Area Network, a network that connects computers and smaller networks over a large geographical area, often using telecommunication links, satellites, or leased lines. The internet itself is the largest example of a wide area network.

The other choices are not standard networking terms; they are constructed to sound similar to the correct expansion but do not correspond to any recognised classification used in computer studies.

Exam takeaway: connect the word wide in WAN to geographical coverage, distinguishing it from a LAN, which covers a small, local area such as a single office or campus.
