    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 a few services of the Internet.

                      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 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, WhatsApp and
                      Skype 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
                      or 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?
