                   i +   WAYS TO CONNECT TO THE INTERNET
                  To connect your computer to the Internet, you need an Internet connection. There are
                  numerous ways to connect your computer to the Internet. Some of the most widely used
                  ways are:

                  Dial-up

                  Dial-up requires users to link  their phone line  to a computer in order  to access the
                  Internet. It doesn’t allow users to make or receive phone calls through phone service
                  while using the Internet.

                  Broadband Connection

                  Broadband is provided  through  either  cable or  telephone  companies. It has a
                  high-speed Internet connection. You can share a large amount of data. It is significantly
                  faster  than  a dial-up  connection  and  makes or  receives phone  calls. A broadband
                  connection provides Internet access only through cable.

                  Wi-Fi

                  Wi-Fi (Wireless Fidelity) is a network of wireless connection.
                  It is a mode of communication network that is connected by
                  radio frequency like that of Bluetooth, but it has more power,
                  resulting into a stronger connection.
                  Wi-Fi doesn’t require  cable  to provide  Internet  access. The
                  main advantage of wireless is the “always on” connection that
                  can be accessed from any location under network coverage.
