                      Hypertext Transfer Protocol (HTTP): It is a set
                     of rules that defines how the web pages transfer          Rivers have multiple streams to stay
                     information  like  document,  file,  image,  video      connected, just like computer networks

                     It is secure version of HTTP. The information is
                     converted  into code  to  prevent  unauthorised
                     access. Nowadays, most of the websites uses the HTTPS protocol instead of HTTP.

                      File Transfer Protocol (FTP): It is a set of rules that allows file uploading and downloading
                     from the other computers over the Internet.

                      Transmission Control Protocol/Internet Protocol (TCP/IP):  It  is  a  network  protocol
                     that defines how the information or messages are routed from one end of a network to
                     the other.
                      Post Office Protocol Version 3 (POP3): It is an Internet standard protocol that allows e-mail
                     clients to retrieve e-mail messages from an e-mail server.

                      Internet Message Access Protocol  (IMAP): It is an e-mail protocol  that  stores e-mail
                     messages on a mail server and allows the user to view, access and manipulate the messages
                     on the mail server from their computer.

                      Simple Mail Transfer Protocol (SMTP) : It is an e-mail protocol for sending e-mail messages
                     across the Internet.

                         The computer network means the system of interconnected computers.
                         The components needed for a network are Network Interface Card, networking cable,
                        hub or a switch and router.

                         The different types of networks are PAN, CAN, LAN, MAN and WAN.
                         Various types of topologies used in a network are bus, star, tree, ring and mesh.
                         There  are  two  types  of  computer  network  architectures—peer-to-peer  network  and
                        client-server network.
                         It is  the most popular wireless  communication technology used for homes,  private

                         Bluetooth  is a  technology  that  enables  wireless communication between  low-power
                        consumption devices within a short range.
                         Protocol is a set of rules that governs the communication between computers over a
                        network.
