In computer networking, the abbreviation LAN stands for which of the following?

Introduction / Context:
Computer networks are often classified by their geographic scope and scale. Terms like LAN, MAN, and WAN describe whether a network covers a small local area, a metropolitan region, or a wide geographic area. LAN is one of the most common acronyms used in home, office, and campus networking. This question checks whether you know the full form of LAN in this context.

Given Data / Assumptions:

• The acronym LAN is being used in the context of computer networking.
• The options provide several possible expansions of LAN with different words starting with L, A, and N.
• We assume standard networking terminology as taught in basic computer courses.
• The focus is on the correct, widely accepted expansion of the abbreviation.

Concept / Approach:
LAN stands for Local Area Network. A local area network connects computers and devices within a relatively small physical area, such as a home, office, school, or building. It is distinct from a wide area network (WAN), which spans larger distances, and from a metropolitan area network (MAN), which covers a city or campus. The words line, linear, and land do not correctly describe the type or scope of the network in standard terminology. Therefore, Local Area Network is the only option that matches the standard networking definition of LAN.

Step-by-Step Solution:
Step 1: Recall that LANs are used to connect devices within a limited geographic area, such as a single office floor or building. Step 2: Associate the term local with something nearby or confined to a small region, which matches the idea of a small network. Step 3: Recognise that area refers to the geographic coverage of the network. Step 4: Understand that network refers to interconnected computers and devices that share resources and communicate. Step 5: Put these together to see that Local Area Network accurately describes the concept of a LAN. Step 6: Compare this with the alternatives (Line Area Network, Linear Area Network, Land Area Network), which are not standard phrases in computer networking.

Verification / Alternative check:
Networking textbooks and certification study guides consistently define LAN as Local Area Network. They provide examples of Ethernet LANs, Wi Fi LANs, and office LANs, reinforcing this definition. In contrast, no reputable source uses Line Area Network, Linear Area Network, or Land Area Network as networking terms. Router and switch configuration interfaces also refer to LAN ports and LAN settings in exactly this sense, confirming that Local Area Network is the standard expansion.

Why Other Options Are Wrong:
Line Area Network: Not a recognised term in networking; line describes a single link, not a network type. Linear Area Network: Also not standard; linear refers to shape, not to the scope of a network. Land Area Network: Sometimes mistakenly guessed, but not the correct expansion used in textbooks or industry.

Common Pitfalls:
Students may guess Land Area Network because LANs often exist within a particular piece of land, such as a building or campus. However, official terminology uses the word local, not land. To avoid this mistake, remember the commonly paired terms LAN, MAN, and WAN: Local, Metropolitan, and Wide Area Networks. Thinking of these three together reinforces the correct expansion of LAN as Local Area Network.

Final Answer:
In computer networking, LAN stands for Local Area Network.
