Friends communicate through email. Professors and students communicate through email as well. This video lays out the basics of how email sending and receiving works.

Protocols, History, and Wired Networks.

Protocols are rules and guidelines for the way data is exchanged within the computer of between different computers. History is the storage of all the places you have been on a particular computer. History varies between users on the same computer and can be tracked and managed easily depending on the web browser that is used. Wired networks use ethernet cables to connect the computers to the network router. There are both wired networks and wireless networks.

Browsers

I didn't realize that browsers were just software applications used for retrieving and presenting information on the World Wide Web. Information is identified by a URI, which is a string of characters used to name a resource, and it may be in the form of a web page, image, video or particular content. There are many different browsers but the most popular ones are Firefox, Google Chrome, Safari, and Internet Explorer.
