We have already learned in our earlier classes that the most popular use of the Internet is to
            retrieve information. It is a huge storehouse of information on all topics such as news, politics,
            scientific inventions, etc. In this chapter, we will learn about a few services offered by the Internet.





                      SERVICES ON THE INTERNET
            Internet provides various services for users. Let’s learn about a few internet services.


            SEARCHING INFORMATION

            The Internet is  a vast platform filled with endless data  on topics  such as news,
            healthcare, entertainment, products,  etc.  This information  has been published  on

            websites by people or companies. We can search for any kind of information on the
            Internet by using the search engine. Google is the most the popular search engine. To search for
            something on the Internet using Google, Type www.google.com on the address bar of the browser
            and click on the Google Search option or press the Enter key .



                 PURE
                 FACT        A single Google query uses 1,000 computers in 0.2 seconds to retrieve an answer.




            INSTANT MESSAGING
            Instant messaging allows us to exchange messages (text, pictures, etc.) between two or more
            people at different locations connected to the Internet. It allows us to create a group that may
            consist of friends, family or people at work, with whom we can chat privately. When anyone in the

            group comes online, all the others who are also online are notified of
            his or her presence. Facebook Messenger, Yahoo Messenger and
            Skype are some applications used for Instant Messaging.

            VIDEO CONFERENCING
            Video conference is a live meeting held between two or more geographically separated people. Each

            participant requires a video camera, a microphone, speakers and a high-speed Internet connection
            to transmit audio and video data. As we speak, members of the meeting hear our voices on their
            speakers. Anything in front of the camera, such as the person’s face, appears in a window on each
            participant’s screen. Video conferencing is used in businesses to conduct meetings, to conduct
            online classes for students located anywhere in the world, and in the healthcare industry by doctors
            to interact with patients and colleagues. Examples of applications that
            support video conferencing are Google Meet, Skype and Zoom.
