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.
