A basic system has a client, server, and a transmission medium. The client will send the server a request for a service in which it provides through the transmission medium. The server will then send the client a response back through the transmission medium. However, the transmission medium has to follow certain protocols (rules) which dictate the communication that is being passed through. Information like a song or photo in which a client might want has to be converted into digital information. This process is called digitizing, but depending on how much bandwidth (the transmission capacity of a computer or communications channel) is needed the picture or song might not be able to fit onto the location in which it it destined. Information that is being passed through the transmission media can travel through two forms of media; cable media or wireless media. Cable media is used when a transmission has a likely hood of having interference. Cable media runs a less likely risk of an outside source interfering with communication. Wireless media is used when a person needs to be mobile.
