Which type of network (LAN, MAN, WAN, CAN, PAN) would you recommend for: ▪ A bank with multiple branches across India ▪ A smart home system ▪ A university campus Justify each answer in 2–3 sentences.
SOLUTION....
1. A bank with multiple branches across India → WAN (Wide Area Network)
A WAN is best suited because it connects geographically distant locations over a very large area, even spanning countries. A bank needs secure and reliable communication between its head office and branches all across India, which is possible through leased lines, VPNs, or dedicated wide area connections. This ensures centralized data management, secure transactions, and real-time updates across all branches.
2. A smart home system → PAN (Personal Area Network)
A PAN is ideal because it connects devices within a very limited range, typically a few meters, around a person or home environment. Smart home devices like smartphones, smart speakers, lights, and security cameras usually communicate via Bluetooth, ZigBee, or Wi-Fi, all of which fall under personal networking. PAN provides low power consumption, easy setup, and secure short-range connectivity suitable for home automation.
3. A university campus → CAN (Campus Area Network)
A CAN is most appropriate because it is designed to connect multiple buildings and departments within a defined area, such as a university campus. It provides high-speed networking for classrooms, labs, hostels, and administrative offices within the campus boundaries. CAN allows efficient sharing of resources like servers, databases, and internet connections while maintaining security within the institution
Bank (India-wide branches): WAN – for long-distance, secure inter-branch communication.
Smart home: PAN – for short-range device connectivity.
University campus: CAN – for high-speed, resource-sharing within campus limits.
