    We have already learnt 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 in the address bar of the browser
                      and click on the Google Search option or press the Enter key .

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

                      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. Messenger, Telegram and WhatsApp are some
                      applications used for Instant Messaging.

                      VIDEO CONFERENCING
                      Video conferencing 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, Microsoft Teams and Zoom.

                                               Where is the name 'Google' derived from?
