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 lets break it

down and look at each part individually.

Break it Down

ProtocolSubdomainDomain nameTop level domainFolderFile NameFile Extension

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

Break it Down

PROTOCOLThe protocol enables the browser and server to

communicate with each other. Since the server can handle many programming languages we must identify what what we are saying.

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

SUBDOMAINThe subdomain identifies which section of server

space you want to work with for the given domain. An example of this would be if I wanted to group all my client pages in their own section. I could then put them in a subdomain that could be accessed with 'clients.commonjoedesigns.com'.

If 'www' or sometimes no subdomain is given then the server will give you the available files at the root level for the domain.

Break it Down

DOMAIN NAMEYou would probably agree that every house in the world

has a different address. The same is true for computers. They must have their own address to distinguish themselves from other 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 I.P. address of 69.89.31.70

These numbers are difficult to remember however so something was created called domain names. These are given words that make sense to the reader and are linked to the I.P. address. This way the user has something easier to remember.

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. Take note that the public at large cannot use certain domains such as '.edu' or '.mil'. This list comprises the original list of top-level-domains but there are several more today such as '.tv' or '.us' which is known as a Country Code TLD

.com - generic or commercially oriented sites.edu - educational institution websites.net - generic or network oriented sites.org - noncommercial (non-profit) organizations

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. Once on the actual computer folders can be used to organize files into a sensible manner for easier retrieval or maintenance. Common folders would be 'images', and 'documents'. This could be compared to someone finding your house and then knowing what room to look in for something. What they are looking for does not have to be in that room though as you could put it anywhere you want.

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. If it is .doc the browser knows you need to download the file for your default text program and prompts you to do so. If it is .xls it looks for your default spreadsheet program. If no filename is given then the server will load a 'default' start page for the folder it is looking in.

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.
