Given that wi-fi time is still limited due to take-off and landing procedures, many passengers have opted not to pay for it. Also working against a strong demand for wi-fi is that many people already have smartphones, laptops and other devices that contain entertaining content without the need to access the Internet.There is almost certainly a market for wi-fi access in the air on cross-country flights, especially for business travelers and those who feel like they can get some work done while in the air. It's never going to be for everyone as a pay service, although there will likely be other ways to monetize the service outside of simply paying for it.Google's push to get its browser in front of more users is probably the bigger marketing component to the campaign. Chrome is competing for market share against Microsoft's Internet Explorer and Mozilla's Firefox browsers. Chrome will gain some market presence, but it has a stiff climb against its two established competitors. The fact that is testimony to Google's supremacy over the Internet is its transcendence from being a name to being a verb in the English dictionary. All over the world, whenever people need information on just about anything under the sun, they 'Google' it! Since the first day I became a part of Google fan base, I have been curious about how does the Google search engine work and deliver its services with such consistency and accuracy. That is when I 'Googled' about the Google search engine's inner workings! The results of my research are presented in the following write up.Before delving deep into the anatomy and working of the Google search engine, let us know a little bit about the history of the marvelous search engine and how it came into being. The entity that rules the Internet today had modest beginnings (like all Silicon Valley start ups) in a garage in Menlo Park, California. The idea behind Google search engine has roots in the research project of company founders, Larry Page and Sergey Brin, when they were pursuing their PhD at Stanford University in circa 1996. They wrote an algorithm for web search (patented as 'PageRank' later), that weighed the importance of a page on the net, according to the number of links that were directed towards it. Instead of just searching for relevant keyword density like conventional web search engines, they gave importance to incoming links towards the page and the relevancy of those pages. Google domain name finally got registered in 1997 and since then it has grown by leaps and bounds to become the premier web search engine on the Internet. Through acquisitions and innovations, Google has inculcated a lot more services to its web search features like YouTube, Google Earth and the recent launch of Google TV. Google offers advertising solutions through its Google AdSense and Google Adwords programs. Google's revenue is generated through advertisements placed by it on websites that submit themselves to their programs. This fact must have solved the prime curiosity of people about how does Google make money. After that brief overview of beginnings of the Google search engine, let us explore its inner workings. Know more about what is Google PageRank.The aim of Sergey Brin and Larry Page in designing the algorithm was to build the perfect search engine that could fetch the most relevant information to any query. Let us see how Google search engine works. The secret behind Google's working is its web crawler bot which travels through the length of breadth of the Internet, indexing every new page that gets published. How does the crawler discover new pages? The crawler looks for new links on pre-indexed pages and crawls them as soon as they become live. Every page that is indexed, goes through a range of 'checks'. The number and content of web pages linking to that page is checked (which decides its importance) and it goes through a rigorous quality check in terms of content, code and other features. A snapshot of the page gets saved in the Google cache, which is located on one of the Google servers, in the many data centers it has around the world. When you search for anything, Google searches its vast cached database of pages on its local server, applying various filters of relevance, to provide the most accurate of search results! Now Google even provides a personalized search, whereby your results are customized according to usage history. Google handles more than a billion queries daily in this manner! There are more than 100 parameters including incoming links, content and page history that are given importance when displaying a page in a search query. All this happens within fractions of seconds. This was a very short summary of how Google works. Hope this article has somewhat lifted the veil from the inner workings of the Google search engine for you. Google will of course never reveal the algorithm that makes it possible for it to deliver accurate results and the technology that makes the delivery of billions of search queries possible, as it is it's trade secret. It is constantly evolving as a search engine, while making new changes in strategy like the introduction of the 'Google Instant' feature recently, which delivers results as you type! It is also a demonstration of the brute strength of Google servers established around the world. May Google keep improving as a search engine with time and go forward towards its goal to make all of world knowledge accessible to human kind. Have you ever noticed how Google or any search engine's box shows certain past searches you might have typed earlier? It may get some people into trouble and some may even thank it! It is actually your Internet browser which is keeping a record of the past searches you carried out. You may want to delete Google search history from time to time, if you want to keep your past searches a secret from the inquisitive minds around you. For example, if an unmarried girl is searching for pregnancy symptoms from her home computer, she might want to keep her search away from her parents and other family members. This is where the need to clear Google search history arises. Read more on Google search engine. But before jumping to the steps on how to clear Google search history, let me first explain few basics of Google search history. Google history is a record of all the previous Google web searches that have been performed from your computer. Accessing Google web history is very simple, and so is clearing Google history! Here's how to access Google history. If you have Internet explorer or Mozilla Firefox as your default web browsers, when you go to Google and start typing your required search in the Google's search box, you will get a "drop down" box. This box will display a list of all the words you searched for in the past, in the Google search box. This means that when you start typing a word in Google's search box, you will be shown a list of similar keywords that contain first letters of what you have typed, that you searched for in the past.
