Document Summary

Network externality: the more people that use a network, the more valuable that network becomes. Computer network: collection of computers that transmit/receive electronic signals through transmission media (optical fibre cables, wireless media or radio frequencies) Personal area network (pan) devices are connected within a very small area (within a few metres). For example, a computer with a wireless mouse and wireless keyboard would be part of a pan. Local area network (lan) computers are connected within a geographically limited area. For example, the computers in the library would be on a lan. Metropolitan area network (man) computers are connected over a geographic region that is bigger than a lan but smaller than a wan. For example, a university might use a man to connect all of the smaller lans on campus. Wide area network (wan) computers are connected across geographically dispersed regions. For example, the internet would be considered a worldwide.
