For a long time, people relied on volumes of encyclopedias for all the information they needed. But the idea of an online encyclopedia is not more than 35 years old.
Search engines, a sort of online encyclopedia came into being at the beginning of the Internet era. The most popular of them is Google. Got questions or need information about anything under the sun or beyond? Google has got it all.
A search engine is a program that searches the internet and finds webpages based on the keywords that you provide. When it was first released in 1995, Google was considered unique because of the technology it used. In those days, search engines ranked results based on how often a search term appeared on a webpage.
Google used something called PageRank, which allowed them to determine the relevance of a website by considering the number of pages, along with its importance using a technology known as backlink analysis. This simplified web searches.
