Chapter 7 Summary

I thought the G in 1G, 4G, 5G, etc. networks were supposed to be for the speed at which data could travel, not the generation in which the phone was manufactured.  Blasted T-Mobile advertisements...  These devices did have some wireless features, although if you know me, you’ll know that I highly prefer wired connection for its reliability.  Nonetheless, I have a phone, and while it is serviceable as is, there is nothing I can do to turn it into a wired device unless I used a router’s charging-to-ethernet configuration or whatever I may have learned in my CIS-121 class (although I could be mismembering information and it can only be ethernet-to-charging).

GPS is for global positioning system.  Thanks, Cengage!

Now, I’m all too familiar with a smartphone—we are all too familiar with smartphones; we own smartphones and use them regularly, even when it could be dangerous (looking at you, texters-and-drivers).  However, what I did not know was that, by definition, it is a cellphone with the functionality of an operating system.  Also, I am amazed by the obstacles that companies had to and did overcome.  They had bandwidth as an obstacle, and seeing this now, I am pleasantly surprised that radio frequencies generated by phones do not interfere with other radio frequencies and end up jumbled together in a mess.  I suppose transmitters and towers help, although I do not know exactly how they function.
