How is internet connectivity important when a user clicks a hyperlink from an external source in the world wide web?
Answers
Answer:
In computing, a hyperlink, or simply a link, is a reference to data that the reader can follow by clicking or tapping.A hyperlink points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is called anchor text. A software system that is used for viewing and creating hypertext is a hypertext system, and to create a hyperlink is to hyperlink (or simply to link). A user following hyperlinks is said to navigate or browse the hypertext.

A web browser usually displays a hyperlink in some distinguishing way, e.g. in a different color, font or style. The behavior and style of links can be specified using the Cascading Style Sheets (CSS) language.
In a graphical user interface, the appearance of a mouse cursor may change into a hand motif to indicate a link. In most graphical web browsers, links are displayed in underlined blue text when they have not been visited, but underlined purple text when they have. When the user activates the link (e.g., by clicking on it with the mouse) the browser displays the link's target. If the target is not an HTML file, depending on the file type and on the browser and its plugins, another program may be activated to open the file.
The HTML code contains some or all of the five main characteristics of a link:
link destination ("href" pointing to a URL)
link label
link title
link target
link class or link id
It uses the HTML element "a" with the attribute "href" (HREF is an abbreviation for "Hypertext REFerence"[11]) and optionally also the attributes "title", "target", and "class" or "id":
<a href="URL" title="link title" target="link target" class="link class">link label</a>
To embed a link into a web page, blogpost, or comment, it may take this form:
<a href="http://example.com/">Example</a>
In a typical web browser, this would display as the underlined word "Example" in blue, which when clicked would take the user to the example.com website. This contributes to a clean, easy to read text or document.
When the cursor hovers over a link, depending on the browser and graphical user interface, some informative text about the link can be shown, popping up, not in a regular window, but in a special hover box, which disappears when the cursor is moved away (sometimes it disappears anyway after a few seconds, and reappears when the cursor is moved away and back). Mozilla Firefox, IE, Opera, and many other web browsers all show the URL. In addition, the URL is commonly shown in the status bar.
Normally, a link opens in the current frame or window, but sites that use frames and multiple windows for navigation can add a special "target" attribute to specify where the link loads. If no window exists with that name, a new window is created with the ID, which can be used to refer to the window later in the browsing session.
Creation of new windows is probably the most common use of the "target" attribute. To prevent accidental reuse of a window, the special window names "_blank" and "_new" are usually available, and always cause a new window to be created. It is especially common to see this type of link when one large website links to an external page. The intention in that case is to ensure that the person browsing is aware that there is no endorsement of the site being linked to by the site that was linked from. However, the attribute is sometimes overused and can sometimes cause many windows to be created even while browsing a single site.
Another special page name is "_top", which causes any frames in the current window to be cleared away so that browsing can continue in the full window.
