A web resource is actually anything that can be found in the world wide web. Examples of web resources include databases, web services, web pages, and e-mail. While there are many web resources nowadays, they are very different to what was in place 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, there has been a shift from static to dynamic web pages that display information in response to the actions of a visitor. Web resources are now readily available and in more than one way. Uniform Resource Locators (URLs), are mediums used to identify a web resource on the internet.
Emergence of search engines
During the inception of the web, information couldn’t be accessed from a central resource. This meant that you had to remember the URL of a web resource in order to access it. With time, directories were created and this brought about some organization to the internet. The development of more directories meant that some websites were only available in some directories and not others. It became quite a hassle to find what you were specifically looking for.
Search engines took advantage of directories and brought about a simpler way of finding information stored in directories. With search engines, you didn’t have to know the name of the resource -rather, you simply had to type in a keyword and get results. 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. This has enabled the work of sorting, indexing, ranking, and retrieving information to be left to automated programs.
Evaluating search results
The invention of search engines has considerably transformed the manner in which people access resources on the internet. 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. Check the format of the URL, name of the domain, who published it, and its type. A government domain is different from a commercial, educational, or military domain. You should also look at the author and the sources cited. 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.
