All the computers are communicating via a NETWORK But in this network, we can also share information with the world thus creating a “network of networks” This resulting inter-network of computers and connections is called the Internet 5/25/2017 Mr. Robyn TGJ2O •A web page is a collection of text and pictures that tells the author’s story. •Your web page will allow people to look at what you have put together by using a web browser. Ie. Internet Explorer, Firefox •Features such as “hyper links” which allow you to jump to other features on your page or other locations in the world can be placed on your web page. 5/25/2017 Mr. Robyn TGJ2O A set of documents that use the Internet structures but which are accessed only locally The same browser (Eg. Internet Explorer) that works on the Internet will also allow you to look at local files and pictures. You can write a web page for use on the school intranet, but the world wont be able to see it. 5/25/2017 Mr. Robyn TGJ2O Remember, a network connects computers, so that they can share resources. Basic structure of the web -> think of it like a city. Like a house, every computer has a unique address so that it can be found. Example, 201.123.99.214 The numbering system is like a postal system, narrowing down from country, to institution, and ultimately to an individual computer. This is called your IP address (Internet Protocol) Information is exchanged by sending small packets of data that contain the computer address of the recipient. 5/25/2017 Mr. Robyn TGJ2O Ideas on a web page can be linked to other ideas on other pages! This is accomplished using hypertext Hyper referes to the idea that the text is non-linear. Example: Rather than following the text from the beginning to the end, you can click on a hypertext linked word and it will take the user to another web site. See what I mean? 5/25/2017 Mr. Robyn TGJ2O It is the web standard for transmitting and storing all of the data on the internet. Hyper Text Markup Language Used by the first browser called mosaic 5/25/2017 Mr. Robyn TGJ2O Text means you will be using plain text files. Markup Language means you will e adding “tags” to the text file to tell the browser how it should display the text. For example <B>This will bold the Text</B> In you browser, click on “View” and then “Page Source” to see HTML Tags. 5/25/2017 Mr. Robyn TGJ2O Microsoft Internet Explorer Opera Mozilla Firefox Safari 5/25/2017 Mr. Robyn TGJ2O Location or Address Bar Use to enter the address of the sites you want to find. This address is called a URL (Universal Resource Locator) The URL is made up of a number of components. The first part, http (Hyper Text Transfer Protocol), describes the service being used. http is the service used to send HTML web pages. Other services include “ftp” for file transfer. The next part (example: www.tsn.ca) locates the server computer which has all the HTML files to view. 5/25/2017 Mr. Robyn TGJ2O Search Engines located on the browser to find what are you looking for more quickly. 5/25/2017 Mr. Robyn TGJ2O These buttons take you back one page or forward one page. 5/25/2017 Mr. Robyn TGJ2O This button will bring you back to your home page, the page you started at. 5/25/2017 Mr. Robyn TGJ2O When you connect to the internet, you are using two computers. Your home computer is connected to a computer operated by your Internet Service Provider (ISP) Your computer is called the client. Your ISP’s computer is called the server. The server provides connections with other servers around the world. 5/25/2017 Mr. Robyn TGJ2O Various companies have developed search engines that keep indexes of the information available on the internet. People who make web sites, register them on search engines and provide “key words” so people can find their site. 5/25/2017 Mr. Robyn TGJ2O Online etiquette is often referred to as "netiquette". Remember: You are communicating with real people, not machines. Rules: 1. Never give your whole name, address or phone number to anyone. You never know who is lurking in the shadows 2. Don’t flame anyone. This means don’t use profanity or make rude comments. 3. Dont’ spam. This means don’t advertise unless you have the permission of our Internet provider. 4. Never write all in caps. IT IS EQUIVALENT TO SHOUTING (and it’s hard to read) 5/25/2017 Mr. Robyn TGJ2O http://www.webopedia.com/quick_ref/timelin e.asp 5/25/2017 Mr. Robyn TGJ2O http://video.google.ca/videosearch?q=Timeli ne%20of%20the%20Internet&oe=utf8&rls=org.mozilla:enUS:official&client=firefox-a&um=1&ie=UTF8&sa=N&hl=en&tab=wv#q=Internet&hl=en& emb=0&client=firefox-a&start=10 5/25/2017 Mr. Robyn TGJ2O
