Wired Internet Connection

            Dial-up Connection: It is a type of connectivity that uses modem and the telephone lines to connect to the
            Internet.   modem must be connected to a telephone  not in use for voice calling . It is a commonly used
            connection for home PCs to connect to the Internet.

            In this type of connection  the speed of data transfer is less in comparison to broadband or  S  and the
            Internet connectivity has to be established each time whenever a user switches ‘ON’ the computer or uses the
            telephone line for voice calling.
              DSL/Broadband Connection: In telecommunication, broadband is a term which refers to broad bandwidth
              network  which  uses  copper  phone  line.   S   enables  broadband  connectivity  that  connects  without
              disturbing the use of telephone line. It is a signaling method which handles a relatively wide range of data
              transfer at higher speed.  S  stands for  igital Subscriber  ine.  arlier   S  was known as  igital Subscriber
               oop. Nowadays optical fiber is used for providing high-speed Internet connection.
              Leased Line:  he most recently rolled out form of Internet connection is Optical fiber  broadband which is
              popularly known as   eased  ine . Optical Fiber broadband claims to offer more consistent and reliable speed
              than  S  broadband allowing multiple devices to perform high capacity tasks simultaneously  without any
              slowdowns or breakages in the connection, making it an attractive proposition.

              Cable Internet: Cable provides an Internet connection through a cable modem and operates over cable TV
              lines.  Cable connects to the Internet through a coaxial cable usually using the same line as our TV service.
               able connections offer very high speed  but the connection may be shared with other users.  his means
              that you can experience much slow speed due to congestion.


            Wireless Internet Connection
             et us now learn about some terminologies associated with  ireless Internet  onnection.

            Wi-Fi
             i-Fi   ireless Fidelity  is a network of wireless connection. It is a mode of communication network that
            is established by radio frequency like that of Bluetooth, but it has more power, resulting into a stronger
            connection. Wi-Fi is sometimes called ‘Wireless Ethernet’. Wi-Fi connections are commonly established in
            electronic gadgets including video game console, home networks, PDAs, tablets, mobile phones, i-Pad, i-Pod,
            etc.    i-Fi-enabled device such as a    or     can connect to Internet within a range of   i-Fi  wireless
            network that is connected to the Internet.

             o form a wireless computer network  a  i-Fi adaptor     .   b g  is re uired on computer or terminal
            device. For establishing connection in a local area, access points/hotspots are installed that increase and
            coordinate the frequency for transmission and for regularising the bandwidth of data transfer.

                 Do you know?


                  otspots  ccess  oints are sites that offer Internet access over a  ireless  ocal  rea Network     N .
                  otspots utilise  i-Fi technology  which allows electronic devices to connect to the Internet or exchange
                 data wirelessly through radio waves.  otspots can be phone-based or free-standing  commercial or free
                 to the public.
