How Web Resources Have Modernized the World Wide Web
A web resource is actually anything that can be found in the world wide web. Examples of web resources include e-mail, webpages, databases, and web services. Resources that can be found on the web at present are very much different from those that were available at the inception of the internet.
In those times, only static documents were available and this limited the way information was handled and displayed on the internet. Nowadays, the web has become dynamic and only displays information that you are looking for. In fact, anything that can be obtained through the internet is a web resource. To do this, Uniform Resource Locators, URLs, are used to identify the particular resource on the internet.
Emergence of search engines
When the web was created, a lot of the information wasn’t stored in a central place. You had to remember the URLs of each resource in order to access it. The emergence of directories brought about organization to the web. However, many directories were later developed and some contained fewer websites. It became quite a hassle to find what you were specifically looking for.
When search engines emerged, they harnessed the power of directories and brought about a simple way of searching for information. To find a resource, you didn’t need to know its specific URL. However, search engines too don’t have everything available on the web since some web resources -such as premium content that is only availed to subscribers -cannot be indexed by search engines.
Search engines not only crawl the internet, but also have some interface that allow users to interact with information that has been retrieved. This is done through an algorithm, which is basically a set of rules that govern how content is indexed on the search engine result pages. All the searching, indexing, ranking, and retrieving of data on the search engines is done through an automated program.
Evaluating search results
While search engines have revolutionized access to web resources, this doesn’t mean that you will always get helpful information with every search. The ease and freedom of posting information on the internet has led to many of them posting information that is incorrect, false, and damaging. Before you cite or use a web resource, you need to evaluate it.
To evaluate a web resource, you have to check the URL. Look at its format, domain name, type, and publisher. A government domain is different from the educational, commercial, or military domain. Consider the resources cited and the author of the content that is found on the domain. Lastly, you need to check the comments, opinions, and links pointing to the site. Evaluation is the best way you can use to ensure that you are getting credible information from the web.
