What happens when you do a Web Search?

        The first thing when you are doing a google search is that you aren't actually searching the Web rather you're searching Google's index of the Web.

 Google does this with Software programs called " Spiders".Spiders start by fetching a few web pages then they follow the links on those pages and fetch the pages and fetch the pages they point to and follow all the links on those pages and fetch the pages they link to and so on until we've indexed a pretty big chunk of the web many billions of pages stored across thousands of machines.

For Example, I want to search ' How Fast a cheetah can run"

 I type in my search, say Cheetah running speed and hit return. Google Software searches our index to find every page that includes those search terms. In this case, there are hundreds of thousands of possible results. How does Google decide which few documents that I really want?
    
     This is by asking questions more than 200 of them, Like how many times this page contains your keyword?. Do the words appear in the title, URL, directly adjacent.

 Does the page include Synonyms for those words?
Is this page from a quality website or it is a low quality or even spamming?. What is this pages Page Rank?

 That's a formula invented by our founders Larry Page and Sergey Brin that rates a web page's importance by looking at how many outside links point to it and how important those ink are.

   Finally, we combine all these factors together to produce each pages overall score and send you back your search results about half a second after you submit your search.

 Google does not accept payment to add a site to our index, update it more frequently or even improve its ranking.

 Let's take a look at my search results.

    Each entry includes a title, a URL and a snippet of text to help me decide whether this page is what I'm looking for. I also see links to similar pages and related searches that I might want to try next.

Google is recording whatever you say - here's how you can listen to it and stop it

Tech 2# Google is recording whatever you say - here's how you can listen to it and stop it The good news is that the records come with an easy way of deleting all of the information that it collects. Google is recording everything you say in its voice search. As a user, you can browse through every single of these records and listen to it as well. How often people use Google's voice search is a matter of choice but it is mostly used when people don't feel like picking up the phone and still be able to access its basic functions or perhaps sometimes just for the sake of showing off. Why Google keeps these records Google says that the purpose of storing these voice records is to improve its language and recognition tools and thus enhance the search results next time. However, from an individual's point of view, it is indeed not appropriate to know that Google is recording everything you have ever said using that feature and that too for years...

Tech #17 Is Intel in Trouble if Apple Makes Its Own Chips? Intel Corp INTC 38.89 +2.13% Apple Inc. ( AAPL ) may be looking to reduce its reliance on chipmakers Intel Corp. ( INTC )  and Qualcomm Inc. ( QCOM )reportedly working on its own  semiconductors  for its MacBooks and iPhones. Apple Inc AAPL 153.42 -0.45% Qualcomm Inc QCOM 51.75 -0.17% Industry sources told the  Nikkei Review  that the Cupertino, Calif.-based company wants to lower its dependence on Intel for its notebook computer products and is looking to build one based on the ARM architecture. "Notebooks are becoming thinner, while consumers are demanding better mobility and longer battery life. That gives ARM's architecture, which is known for its power efficiency, a very good opportunity," a chip industry executive said in the report. (See more:  Report: Apple May Drop Intel Chips .)

Hackers Attacking Power Grids in U.S. and Europe..

Tech 15# Hackers Attacking Power Grids in U.S. and Europe.. A hacking campaign is targeting the energy sector in Europe and the US with the potential of sabotaging national power grids, a cybersecurity firm has warned. The group, dubbed "Dragonfly" by researchers at Symantec, has been in operation since at least 2011 but went dark in 2014 after it was first exposed, secretly placing backdoors in the industrial control systems of power plants across the US and Europe. Now, Symantec reports, the group has resumed operations, apparently working since late 2015 to investigate and penetrate energy facilities in at least three countries: the US, Turkey and Switzerland. "The Dragonfly group appears to be interested in both learning how energy facilities operate and also gaining access to operational systems themselves, to the extent that the group now potentially has the ability to sabotage or gain control of these systems should it decide to do so," the cyb...
