    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
                           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. 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?
