                  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. It contains
                  billions  of websites  to provide information. And these web sites  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.
