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:

Break it Down

ProtocolSubdomainDomain nameTop level domainFolderFile NameFile Extension

http://clients.jadekite.com/shaunreimers/EasyTech/_lessons.htm

Break it Down

PROTOCOLThe protocol enables the browser and server to

communicate with each other.Common protocols include:http: - Hyper Text Transfer Protocol - common

websiteshttps: - Hyper Text Transfer Protocol - secured

websitesftp: - File Transfer Protocol - used for servers who

handle file uploads and downloadsmailto: - mailservers

Break it Down

SUBDOMAIN

translate.google.comis 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 NAMEYou 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 DOMAINThe 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

FOLDERThe 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

FILENAMEThis 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 EXTENSIONThis 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.
