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, Skype
                  and Zoom.
