where are the exercise files for this course?

URL Basics

  • URL stands for uniform resource locator which is how we access web pages across the internet
  • When a URL is typed into the browser, the browser goes to the internet to request a web page
  • A URL has different pieces to it:
    • http://
      • The protocol portion of the url
      • There are different types of protocols for the internet, ie, ftp, https, etc.
      • This one stands for a basic page request from a web server
      • The domain name
      • When a domain is requested, that domain name is translated into an iP address
      • There is a central database that stores the domain names & associated IP addresses for those domain names
      • When you purchase a domain name, your domain name & ip address are placed into the central database so your web pages can be accessed using your domain name
    • /products
      • Anything following the domain name defines folders/files within the website structure
      • This example says that there is a folder within the adobe website structure called products and the web page we are viewing is located within that folder
    • /dreamweaver.html
      • A web page within the web site
      • This is telling the browser to locate the web page called dreamweaver.html

Transcription: URL Basics

The first thing that we are going to do is to talk about a URL.0000

URL stands for Uniform Resource Locator, which is a bit of a mouthful, to say.0004

But basically it is how we navigate around the web and access one website versus another and also access specific pages within a website.0011

So, let us take a look at domain name first and then we will move into a little bit more advanced type of URL and give you a breakdown of what those pieces mean. 0022

Because when you are creating your own website, you are creating that URL for your own domain name.0034

So, let us take a look at website to start.0041

Now, has a domain name, educator is the name and .com is the extension that is added on to the domain name in order to access the website.0048

So, when you go to that it is actually two different pieces that many browsers do not show the whole thing.0061

So, in, you can see that there is no educator specifically.0068

There is no HTTPS in front of the word educator, and that is because the browser is adding it for us. 0074

But what if we go to a secure type portion of a website, then we will be using a different type of front area and this piece listed in front of the domain itself it is called the protocol.0083

And in order to access a webpage you always use the HTTP or if it is a secure website, the HTTPS standing for secure and that is right before the domain name.0098

So, has the domain name and the protocol hidden, we can't see it until we get into some type of a secure portion of that domain.0113

Let's take a look at the Adobe website, and what am I on now is the Adobe website specifically for Dreamweaver and Dreamweaver CC, this is the upcoming Dreamweaver version.0124

And since it is the most prominent version they are trying to market it that is the version I was able to access on the Adobe website.0141

But it is a perfect example of the different pieces of a URL.0148

So, if we take a look at this one, you will see that HTTPS is listed along with the colon forward slash forward slash that is because this is a secure area of their website.0155

Then next we have the domain name with or without the WWW, and notice that there is some additional information after the domain name, and that is specifically a folder within their website files.0168

So, has a main website and inside of that there is a folder called Products, and within the Products folder you can see there is a file called Dreamweaver.html.0185

That is the page name, and you can have as many folders within this area as you want.0199

So, when you are creating your website files you always have to keep in mind that the user is going to be able to see in this domain and your page names.0205

You want to make them usually readable for the user and there are also going to be able to look at the domain name itself. 0218

You want to make it not only one that is easy for them to type but easy for them to recognize within the URL area.0228

So is a perfect example of showing not just the domain name such as, but we are going even deeper than that.0238

We are going into the secure protocol for HTTP and HTTP is actually just a protocol for asking a web server for a file that you want to look at through your browser.0249

Then, we have the domain name and we also have the folder called products here in this example and within that folder is our webpage. 0264

And notice our webpage we know it is a page because it has the .html attached to it.0274

So, it is pretty obvious on this one that it is a webpage. 0280

Not all websites will show that dot, whatever the file extension is for the webpage, but the full URL would be this piece here, everything you see in order to access that page.0284

And I think the web has been around, so most of us are familiar with navigating across the hyperlinks.0298

But, I tend to find most people who are not involved in the web never even look in that URL area.0304

But, I think it is important to consider when you are creating your own websites, how that URL is going to look for a user if they do look up in that area.0312

It can also affect the book marking piece, but that is the URL for a website.0323

And when you are creating your website specifically, you are the one who gets to create and figure out how is that going to look by adding folders and files within your website files.0330

But that is a Uniform Resource Locator, a way of specifically access an individual page out on the website.0342
