FAQ
Q1: What is a Global Area Network (GAN)?
A: A Global Area Network (GAN) is a network that covers an area larger than a metropolitan area or even a country. It typically involves multiple networks with different technologies and provides services to multiple locations across several geographic areas.
Q2: How is GAN different from LAN and WAN?
A: While a Local Area Network (LAN) is a network system within a restricted area like an office or home, a Wide Area Network (WAN) expands this network across a city, country, or regions in different countries. GAN, on the other hand, is a network that covers an even larger geographical area, often the whole globe.
