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, Skype and Zoom.
