the search engines

One of the miracles of the internet is the search engines. They play a vital role in getting an accurate search for information and evaluating our sources of information. With their help, we can find web pages we don’t know. They can sort out the result of our search through links as they collect the exact information for the index then add the new page to our catalogue. Consequently, we will have immense search on the internet with measureless quantities of varied information. Due to the increasing development in search engines software, we can accurately and easily describe the information we need, enhance the internet and make it more efficient. Really, the world became a small village, nothing is hidden or missed.

Evaluating Internet Resources

In the last few years, the development in the field of communications has developed so fast. Man used various methods to obtain information. One of the most successful means is the Internet. By using the Web resources, we could obtain the information quickly and accurately from more than one source. Unfortunately, in a world full of misconceptions, some people use the Internet badly. A lot of wrong information can be uploaded on the net by some unqualified people or for advertising to convince the users with the sales. Such information may be wrong or dishonest given to convince people with ideologies or policies.

Meanwhile, many students and researchers are using the Internet as a source of research. Therefore, has become necessary for the users to evaluate any website before getting information from it to be sure of the credibility of this information.
it is clear to know how to evaluate any website to get information because the credibility of on-line sources does not satisfy the users of the internet nowadays. Therefore, we should know some criteria for evaluating web pages such as:
• There should be an e- mail or any way for valid contact with the author or the institution who published the page. We should know the purpose and the qualifications of the author.
• Searching for the credentials of the author that listed and if the domain is satisfying to us or not.
• To be sure of the goals of the page in presenting the information and the accuracy of the information, is it clear or might be biased or for advertising.
• If the page is current or updated regularly and the links are up-to-date. Also, if there are any dead links or not.
• It is easy to obtain information for free or for fees and if the page requires special software to view the information.
• If the information is presented and cited correctly or not.
From the last criteria, we could decide if we are dealing with a good or bad website
