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 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, Yahoo  Messenger  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.
