The Internet is a global network of computer networks linked together. It was established in 1969 by the Department of Defense and several large colleges. It was initially used by educational and research institutions in the 1970s and 1980s as a large email network to freely exchange research information.
A hyperlink is either text or an image that is linked to another document. Hyperlinks can link to an entirely different document on the same site, a document on a different site, a video, a sound file, or even an anchor in a document. A broken link is a link that points to a document or resource that is no longer there. A Web server is a computer (server) that waits for requests from browsers (clients) asking for Web documents or resources, then serves up those documents.
A Uniform Resource Locator (URL) is the complete Web address of a Web page or resource. The URL for this page is:
http://www.harrised.com/208/index.php?page=34. As you can see, a URL is composed of several parts. Know parts of a URL (below).
- protocol - a standard for sending voice, data, and video over the network. Hypertext Transfer Protocol (HTTP) is the protocol used to transfer Web pages -
http://in this example.
- sub-domain - is the
wwwin this example.
- domain name - the registered name of the file server -
harrisedin this example.
- top level domain -
.comin this example. Could be .org, or .net, etc.
- path - the file is located in the
208folder or directory. Can have more than one folders.
- file name - in this case it is a php script
A domain name can be registers for less than $10 per year (mydomain.com, godaddy.com, or hundreds of other registrars). Cybersquatting is the registering of a domain name with the sole intent to profit from a trademark belonging to someone else. Typosquatting (or URL hijacking) is the registering of variations of popular trademarked names (ex: gooogle.com). Disputes among domain names are resolved by the Internet Corporation for Assigned Names (ICANN).
Links can point to
- A specific place on the same Web page
- A different Web page on our Web site
- A different Web site
We can create a link to another page with the Insert Hyperlink dialog box below.
To display the Insert Hyperlink dialog box, we can click INSERT HYPERLINK from the VIEW menu, or use the CTRL+K shortcut key.
We can create a placeholder page, a page with little or no content, if we know we want to link to a new page that we have not created yet. To create a placeholder page, from the Insert Hyperlink dialog box, click on the CREATE NEW DOCUMENT button (see red arrow above). Then, we can name the new page and select when we want to edit the page (now or later).
