How we can Access the Internet?
Common methods of Internet access by users include dial-up with a computer modem via telephone circuits, broadband over coaxial cable, fiber optics or copper wires, Wi-Fi, satellite, and cellular telephone technology (e.g. 3G, 4G, 5G).
The Internet may often be accessed from computers in libraries and Internet cafes. Internet access points exist in many public places such as airport halls and coffee shops.
Various terms are used, such as public Internet kiosk, public access terminal, and Web payphone. Many hotels also have public terminals that are usually fee-based. These terminals are widely accessed for various usages, such as ticket booking, bank deposit, or online payment. Wi-Fi provides wireless access to the Internet via local computer networks. Hotspots providing such access include Wi-Fi cafes, where users need to bring their own wireless devices such as a laptop or PDA.
These services may be free to all, free to customers only, or fee-based.
Access Internet Mobile Communication
The International Telecommunication Union (ITU) estimated that, by the
end of 2017, 48% of individual users regularly connect to the Internet, up
from 34% in 2012.
Mobile Internet connectivity has played an important role in expanding
access in recent years especially in Asia and the Pacific and in Africa.
The number of unique mobile cellular subscriptions increased from 3.89
billion in 2012 to 4.83 billion in 2016, two-thirds of the world's population,
with more than half of subscriptions located in Asia and the Pacific. The
The number of subscriptions is predicted to rise to 5.69 billion users in 2020. As
of 2016, almost 60% of the world's population had access to
a 4G broadband cellular network, up from almost 50% in 2015 and 11% in
2012
A study of eight countries in the Global South found that zero-rated data
plans exist in every country, although there is a great range in the
the frequency with which they are offered and actually used in each.
The study looked at the top three to five carriers by market share in
Bangladesh, Colombia, Ghana, India, Kenya, Nigeria, Peru and
The Philippines.
Across the 181 plans examined, 13 percent were offering zero-rated
services. Another study, covering Ghana, Kenya, Nigeria, and South Africa,
found Facebook's Free Basics and Wikipedia Zero to be the most
commonly zero-rated content.
