                 The Internet is a global network of millions of computers and computer networks all over
                 the world. It allows us to access and share information over the network. The Internet has
                 billions of websites that provide information, and these websites contain related web
                 pages. Websites are located by using the website address or Uniform Resource Locator
                 (URL) which is a unique address.


                  i +  REQUIREMENTS TO CONNECT TO THE INTERNET
                 The things required for connecting a computer with an Internet connection are:


                 Telephone Line
                 You can connect the Internet to your computer by using a telephone line.
                 This service is provided by an Internet Service Provider (ISP). These help
                 in establishing a link between the different computers and the servers.


                 Modem
                 Modem stands for Modulator-Demodulator. A modem is a device which modulates
                 (converts  digital  signals to  analog  signals)  from  the  transmitting  workstation  and
                 demodulates (converts analog signals into digital signals) at the recipient’s workstation.
                 The sending and receiving ends of the communication must have a modem. Now a days
                 mobile phones have inbuilt modem devices that help to browse Internet. The modem can
                 be classified as:
                 •   Internal modem: It is already installed inside the CPU of a computer
                    in the form of a card.
