Document Summary
Warning: this lecture is heavy on the acronyms. Machines for personal use (laptops, phones, etc. ) This is what happens when your computer (the client) requests a page and a server responds with the appropriate files. Domain - the server* (optional) document - the specific file needed. Most pages are made up of multiple files. Identifies the entity you want to connect to. Determined by internet corporation for assigned names and numbers (icann) Internet protocol version 6 (ipv6) is the communication protocol that identifies computers on networks. Every computer has a unique ip address xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx. Can represent over 300 trillion unique combinations (2128)! Luckily, you don"t need to remember the ip address of a domain. The dns will lookup the ip address based on the url you type in. If no document is specified, the default document is returned. Once the ip address is determined, the browser creates an http request. Lots of hidden information in this request.
