I want to take a moment and talk about Web delivery and I want to try and explain to you exactly how it works and I'll try and kind of break it down and make it nice and easy to follow along. So, what I've done here is I opened up my Web Browser, Firefox. You can launch your Web Browser as well and it doesn't really matter what Web Browser you use for this. How it works here is, if I come along and I decide to type in a website address, www.vtc.com, for example and I go ahead and hit Enter to lock that in, what happens is my Web Browser makes a request to a Web Server. That's the idea here. That's what this address bar is all about. So Firefox made a request to a Web Server for a particular Web page. Now how it works here is an HTML page, or a Web page, contains all kinds of different sorts of content, not only text but also images and videos and all the rest of it, right? Now, a Web Server on the other side very simply is just a computer that's connected to the Internet and all it does, it's sort of its sole existence, its sole purpose, is to wait for requests from browsers. So when a browser request comes in the Web Server then looks for the data that the Web Browser's looking for, so a Web Server simply stores websites which contain the HTML pages, which contain the images and the video and all the rest of it, right. So, really the VTC website here is just a group of files that are stored on a computer hard drive somewhere, right; that's really all it is. And all this Server does is serves this information to us running the Browser. If the Web Server can find the information that the Web Browser is requesting then it sends it back to the Browser and we get to see the Web page before our eyes, right. Sometimes, though, the information that's being requested isn't found. Like let's say, for example, I come in here and I go vtc.com /geoff photoshop, right? I highly doubt that there's a resource on vtc.com called geoff photoshop and no, there isn't. So what they've done here is they've set up what's called a redirect. It's just going to take you back to something called index.php. Now that's the main page of the website. Now sometimes what happens, though, is you get what's called a 404 error. I'm sure you've seen this. And essentially what that means is that would be like the server saying, hey, I can't find the information that you want. You're out of luck. That kind of thing. And sometimes what happens as well is, let's say in the case of a graphic, I'm sure you've seen this, too, where there's an empty spot on the page where it looks like there should be a graphic there and then usually there's some kind of a broken link icon of some sort, maybe an X or a broken image, or something like that. What that means is that the location of the image can't be found so it can't be loaded into the page. I hope all this makes sense and it's good stuff to know, especially if you're brand new to Web design and brand new to how all of this works.
