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 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, Whatsapp 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.
