What is the full form of 'LAN'?
- A.Line Area Network
- B.Linear Area Network
- C.Local Area Network
- D.Land Area Network
Correct answer
Explanation
The correct answer is C, Local Area Network. A LAN joins computers and devices inside a small area such as one room, one building or a campus. It usually runs on Ethernet cable or Wi-Fi, is owned and managed by a single organisation, and gives a high data transfer rate with very few errors, which is why offices, schools and cyber cafes use it. Networks are classed by the area they cover: PAN for one person's own devices, LAN for a building, MAN for a city and WAN for a country or the world, the internet being the largest WAN. Option A is wrong because 'Line Area Network' is not a networking term. Option B is wrong because no class of network is called a 'Linear Area Network'. Option D is wrong because 'Land Area Network' does not exist either. Exam tip: learn the four by rising size — PAN, LAN, MAN, WAN — and remember the LAN is the one limited to a single building or campus.
