What is Search Engine?
The internet has a hundreds of millions web pages available and each of this contains information that you may be interested with. But with the sheer number of web pages available and the number of domain names that you need to sift through in order to reach the page you want to read, it will take ages to look for it and without any help from something this chaotic scene cannot be tolerated and the pace of our evolution will not be as fast as what we are doing today.
As we search information to the internet, we used search engine like Google, Yahoo or Bing to help us find what we are looking for. For example, we type in weight loss on the search field and a list of website is given to us that have the weight loss keyword tag included in their website. In this way, all we have to do is to look at the list that the search engine provided us and find the most relevant website that has the most viable content to what we are looking for. The search engines already search the internet for the most relevant site for what we are looking for. This decreases our time searching for the information and let us continues with reading and learning the information. Without the help of search engine it will take a long time or nearly impossible to find what we are looking for.
