The operating context HTTP let's just look at how a web pages page again just learn a little more about the relationship between HTTP in with pages some picked an example URL for a page to start with here it is it's a page on Wikipedia for Vegemite so if I ride out the URL you can see that it has several pots the first part is the protocol pop it's HTTP were uninterested here in HTTP URL's because they the ones which have fits with the HTTP protocol if this was something different to different particle would be used to fetch it and then the remainder the URL has two components: one is the server component that???s really telling us which host you can see this is the thesis a DNS domain name what's the name of the host a server and a power after this 646-206 well that's the identification the name of the page that resides on that server so we go through several steps for browser to be able to retrieve and display this page and I'm I am listing them all here just so wean go through the link in a sense where HTTP fits in this is more than HTTP effect the first step is often to resolved the server hostname to Its IP address using the DES we???ve seen how this is done with the Dean yes we need this to be able to contact these once we have the IP address for the server with to set up a TCP connection a sin to be runs atop a TCP so account too much to reopen the TCP connection after we do that which incident which city request now we need to http proper and then once having sent the request the browser will wait to receive a response from the other side from the server will simply be sent on through and then the diesel I'm step here I???ve started just because to indicated there's a lot of complexity that goes in here this state is really the fetching every bid web resources if you have a page which has three images in well.
