Network CS Thinking Example 2
Follow the full solution, then compare it with the other examples linked below.
Example 2
mediumExplain the difference between a LAN and a WAN. Give an example of each.
Solution
- 1 Step 1: LAN (Local Area Network): covers a small area like a single building or campus. Example: a school's internal network connecting all classroom computers.
- 2 Step 2: WAN (Wide Area Network): covers a large geographical area, connecting multiple LANs. Example: a company with offices in London and New York connected via leased lines.
- 3 Step 3: The internet is the largest WAN. LANs are typically faster and more secure than WANs because the data travels shorter distances over infrastructure the owner controls.
Answer
LAN: small area (school building), fast, locally controlled. WAN: large area (multiple cities), connects LANs. The internet is the largest WAN.
Understanding network types helps in planning infrastructure. LANs are cheaper and faster but limited in range; WANs extend reach but add complexity, cost, and security concerns.
About Network
A group of interconnected computing devices that can communicate and share resources with each other. Networks range from small local area networks (LANs) connecting devices in one building to wide area networks (WANs) spanning cities or countries, up to the global internet.
