Graphic User Interfaces
Graphic User Interfaces (GUIs) help users interact with their computers.
If you use a mouse to click on something, it’s probably a GUI
Take a look at the following GUI items:

URL Breakdown - as seen on commonjoedesigns.com
URL means Uniform Resource Locator.
It can be thought of as the "address" of any part of a website.
It is comprised of many parts, so let’s break it down:

Protocol
Subdomain
Domain name
Top level domain
Folder
File Name
File Extension

Break it Down
PROTOCOL
The protocol enables the browser and server to communicate with each other.
Common protocols include:
http: - Hyper Text Transfer Protocol - common websites
https: - Hyper Text Transfer Protocol - secured websites
ftp: - File Transfer Protocol - used for servers who handle file uploads and downloads
mailto: - mailservers

Break it Down
SUBDOMAIN
translate.google.com
is a URL with subdomain “translate”.
Here the:
“ .com” is the first level domain - the top level domain “google” is the second level domain - the domain “translate” is the third level domain - the subdomain
What is the purpose of subdomains?
Subdomains help divide a site into different specialties,
docs.google.com - Google documents
mail.google.com - Gmail
news.google.com - Google news

Break it Down
DOMAIN NAME
You would probably agree that every house in the world has a different address. The same is true for computers. This is done by something called an Internet Protocol (IP) which is a series of numbers and dots. For this website the server it is on has an IP address of 69.89.31.70
You can find the IP address of your computer by typing “IP” into Google.
These numbers are difficult to remember however so something was created called domain names. These are words that make sense to the reader and are linked to the IP address.

Break it Down
TOP LEVEL DOMAIN
The top level domain (TLD) is a way of identifying the purpose of a website. Here are several examples of generic top level domains. The public cannot use certain domains such as '.edu' or '.mil'.
Here are some of the earliest top level domains
.com - generic or commercially oriented sites
.edu - educational institution websites
.net - generic or network oriented sites
.org - noncommercial (non-profit) organizations
.mil - military (army, navy, etc. websites)

Break it Down
FOLDER
The slash "/" after the top level domain can be thought of as a separator. It separates the Internet and the actual computer the file or web page is located on.
Common folders would be 'images', and 'documents'. This is like someone finding your house and then knowing what room to look in for something.

Break it Down
FILENAME
This one is easy! This is the actual name of the file you are viewing. There will always be a file, so there will always be a filename.
FILE EXTENSION
This has the exact same meaning as the file extensions on your computer. The extension helps the browser decide how to handle the file.
Some common file extensions:
.jpg .txt .doc .ppt .xls .mp3 .exe .torrent
If you ever want to check a certain file extension, you can type it directly into Google. Google is your friend.

How to Google Here’s a typical web search results page. What do the numbers below mean?

1. The title : The first line of any search result is the title of the webpage. 2. The snippet : A description of or an excerpt from the webpage. 3. The URL : The webpage's address. 4. Cached link : A link to an earlier version of this page. Click here if the page you wanted isn't available.

Better Searches Make Better Results Here are some modifiers to make Google searching easier… “ ” - ~ OR .. Exact Phrase Exclude Words Synonyms Multiple Words Numeric Range

- Exclude Words What it Does: Removes results with words you don’t want What to Type: ice -cream What You’ll Get: Results about ice, without results about ice cream.
