                        a.   Raghav is trying to access his schoolwork stored on a central server. Which networking feature
                            allows multiple users to access data from one central location?

                        b.   Sanya is learning how data travels on the Internet. She learns that data is broken into small packets
                            and reassembled at the destination. Which protocol handles this process?

                                                                                                  21 st   #Communication

                         Visit your computer lab and explore how different network protocols work during everyday tasks
                         such as browsing  websites,  sending  emails  and downloading  files. Observe which protocols
                         (HTTP,  HTTPS,  TCP/IP, FTP, SMTP, POP3, IMAP) are used  for each  activity.  Create  a short
                         presentation  showing the  protocol  name,  its  purpose  and an example  where it  is  used  in your
                         school network.
