            As we know that the Internet is a computer network that connects hosts and systems
            throughout the world. In this chapter, we will learn about the Internet and e-mail service

            of the Internet in detail.
                THE INTERNET

            The seed of the Internet was planted in 1969 when the Advanced Research Projects
            Agency (ARPA) of the United States Department of Defense began connecting

            computers at different universities and defense contractors. The resulting network
            was called Advanced Research Projects Agency Network (ARPANET).

            In the beginning, ARPANET was a large network serving only a handful of users, but
            it expanded rapidly. Initially, the network included four primary host computers.
            The Internet acts as a carrier for several different services, each with its own distinct
            features and purposes. The most commonly used Internet services are: World Wide
            Web, electronic mail, news, file transfer protocol, chat, instant messaging, online

            services and peer-to-peer services. January 1, 1983 is considered the official birthday
            of the Internet. Before this, the computer networks did not have a standard way
            to communicate with each other. A new communications protocol was established

            named Transmission Control Protocol/Internet Protocol (TCP/IP). The TCP/IP
            allows computers connected to different networks communicate with each other.
                WORLD WIDE WEB


            The World Wide Web (WWW) is a large information system where you can surf
            and get information. It consists of several public and private websites which may
