A link is easy recognizable as it is a highlighted text and it is known as a reference to data. Hyperlinks or links are mostly implanted in articles and other different documents. Once a link is clicked by a user, he/she will be taken to a different section in the document or article that she or he has been surfing on. The link expose information or content related to the article’s or document’s. Some links would direct the user to another website which would not be related to what he or she has been looking at . It is possible for computer links to fail working appropriately; broken links are more likely to conduct the user to moved or removed contents from the web.
Surfing on Internet is very interesting as you learn new things and at the same time discover new manners on how internet have answers to mostly everything. Internet might be useful but sometimes it is in fact a really dangerous place to be if you do not know the consequences of using it inappropriately. There are particular methods of using internet to avoid getting Viruses, spams and much more troubles such as getting bankrupted in few minutes or getting unnecessary emails or inappropriate pop up pages. All these situations occur due to different actions the user makes by clicking and trusting unknown links appearing on their screen which at times seem perfectly safe.
Links of unrequested emails
Unwanted emails can still reach you despite the protections you have arranged them to not arrive to you such as using spam filters to catch them. Spams show up in different ways, some are created to get the user to react to his or her own email by clicking a link to “unsubscribe” which will enable the sender to take the user’s email address and add a spam database of active email addresses. This operation will conclude in the user receiving an enormous amount of spam in his or her inbox.
These links will be appearing on user’s Facebook wallpapers if they have one. They are posts accompanied of a link to an application which will say attention grabbing things such as • I’m travelling and I’ve lost my wallet. HELP • My total Facebook view is: 4455646. Find out about your total views. • See this wonderful video • OMG! Zayn Malik just spoke to me! Click here: These tend to make the user curious and make them want to click on one of these and have a look at the “interesting” message.
Being careful while being on Internet is fundamental, by making sure to avoid any unknown links or replying to any emails that you have never responded to before. Children need to be aware and thought on how to be safe on internet as clicking on strange links due to urge can lead to excessive troubles.
Link awareness is defined as the ability to discover, view, search and update global hyperlink information about any resource with a URL on the World Wide Web. This global link information is a shared information resource.
Implementing link awareness is difficult. In practice, an implementation only approximates link awareness. There are at least two qualitative axes on which we can classify these implementations.
- Breadth of Coverage: The number and type of interlinked documents covered.
- Liveness: The ability (or lack thereof) to update the link information on the fly.
- Most WikiWiki implementations support link awareness within the scope of the documents that they host. Their breadth of coverage (insofar as link information is concerned) is narrow. A wiki, however, is very live (and indeed, liveness, is its raison d'etre).
- Google supports link awareness through its web interface. (You type in a query of the form
link:<URL>.) Google's breadth is impressive (it covers a lot of interlinked documents), but it is a far cry from live (it can take months before Google indexes a newly created document).
