• #3: 03/18/10   The Internet is a vast collection of inter-connected computer networks connecting computers all over the world. No one knows exactly how many computers are connected to the Internet. It is certain, however, that these number in the millions and are increasing at a rapid pace.

So this network of networks is made up of lots of computers or servers, all over the world, that hold information – and ---

There is something for everyone on the Internet – for any interest, hobby, fascination or curiosity that you have, you’ll probably find a community on the Internet that deals with it.   An additional attribute of the Internet is that it is self-organizing and self-governing and has no central authority—in other words, there is no "Internet, Inc." that controls the Internet. Beyond the various governing boards that work to establish policies and standards, the Internet is bound by few rules and answers to no single organization. In other words, each of those virtual cities and towns on the information superhighway basically takes care of itself. So, how did this all get started?

Help. Clicking on these choices brings a drop-down menu of more options. Navigation Tool Bar has icons for commonly used functions and tools that help navigate through web pages. Address bar contains the address or URL of the page. Display Area occupies the majority of the space on the Web Page. Hyperlinks are often underlined text, but can be any kind of graphic. When the mouse pointer changes to a hand, click the left mouse button to access the hyperlink. Scroll Bars are used to view the portions of the page that are not currently on the monitor. Search Box : Many Web pages have a search box to help find the information you need.
• #11: 03/18/10 Use the browser buttons on the tool bar at the top of the page to move between pages and access commonly used functions. Back takes you back a page. The down arrow on the right shows previously viewed pages. Forward moves you forward a page. Stop (red X) stops the page from loading. Refresh reloads the page to show any updated information. Home takes you to the page that displayed when the browser was opened. Search allows you to use a search engine to search for information. Favorites displays a list of Favorite, book marked or saved web sites. Address Bar displays the address (URL) of the page being viewed. Put in a different address and click GO to link to the new Web page.
• #12: 03/18/10 The technical term for a Web address is URL which means Uniform Resource Locator. 1) We can learn a lot about addresses if we understand how they are structured. For example, “the http://” will always be there and that stands for Hypertext Transfer Protocol . The http at the start of Web addresses means we are transferring hypertext documents. The “www” probably will be there, but not always. Following it will be the identifying name of the server – In this case, the tol.lib.ca.us is the Thousand Oaks Library’s Web server. Ideally, this tells you what the entity is that runs the site or what information you are likely to find there. The last portion of this Web address or URL identifies the file name.   2) A most telling part of the address is that portion or extension that identifies the domain, or type of entity represented. I’m sure you’ve all heard of the expression “.com.” This term relates directly to Web addresses. The .com or .org or .edu tells us what type of an organization it is.    A .com is a business or commercial entity. That’s where the .com comes from. Do you recognize this address? Amazon.com was one of the first widely-known Internet business, and it remains a giant the emerging online marketplace. 3) .gov represents government entity. This is a address for the State of California’s Web site. What would you guess .org stands for? Yes. An organization. More specifically, a nonprofit organization such as the American Red Cross. 4) What about .edu?   Yes! That’s an easy one. The .edu signifies a university or college. Grade schools and secondary schools don’t get .edu – they get an extension like K12 and their state and country.   Those are just some of the domain extensions. There are others such as .net as well as geographic domains such as the .ca.us which is part of the library’s Web address.
