A common working definition for "global network" is the following definition: A global network is "any communication network that spans the entire Earth." If you use this definition, then a global network is going to be something like the GSM mobile communication system. GSM stands for "Global System for Mobile communications." Currently, GSM networks are available in 219 countries and allow individuals to be contacted via the same mobile number in each of those countries. GSM networks cover more than 90% of the world's population. The GSM network for cellular communication is a solid, specific example of a global network. It allows communication between individuals and groups from just about any location on the planet. Another example is the Internet, but I feel that is a much more vague example.
