The Internet (2)
Worldwide Internet users
There’s a huge gap between population of the world and the people with Internet access. You can have a look at these stats from International Telecommunications Union
Here is another statistics by ITU which represents a clear range of Internet users and the population throughout the years.
|World population||6.5 Billion||6.9 Billion||7.2 Billion|
|Not using the Internet||84%||70%||60%|
|Using the Internet||16%||30%||40%|
|Users in the developing world||8%||21%||32%|
|Users in the Developed world||51%||67%||78%|
Some governments, such as those of Burma, Iran, North Korea, the Mainland China, Saudi Arabia and the United Arab Emirates restrict access to content on the Internet within their territories, especially to political and religious content, with domain name and keyword filters.
In Norway, Denmark, Finland, and Sweden, major Internet service providers have voluntarily agreed to restrict access to sites listed by authorities. While this list of forbidden resources is supposed to contain only known child pornography sites, the content of the list is secret. Many countries, including the United States, have enacted laws against the possession or distribution of certain material, such as child pornography, via the Internet, but do not mandate filtering softwares. Many free or commercially available software programs, called content-control software are available to users to block offensive websites on individual computers or networks, in order to limit access by children to pornographic material or depiction of violence.

The internet has no centralized governance in either technological implementations or policies for access & usage.
(Laws for torrents & illegal material are imposed by govt. of some specific countries. Internet has NO RULE)
Have a look at this map of the world with level of censorship and surveillance on Internet usage.

It is estimated that ‘Deep Web’ is more than 500 times that of surface web.
An Internet blackout or outage can be caused by local signaling interruptions. Disruptions of submarine communications cables may cause blackouts or slowdowns to large areas, such as in the 2008 submarine cable disruption. Less-developed countries are more vulnerable due to a small number of high-capacity links. Land cables are also vulnerable, as in 2011 when a woman digging for scrap metal severed most connectivity for the nation of Armenia. Internet blackouts affecting almost entire countries can be achieved by governments as a form of Internet censorship, as in the blockage of the Internet in Egypt, whereby approximately 93% of networks were without access in 2011 in an attempt to stop mobilization for anti-government protests. Many Government have control over their citizen’s Internet usage and can prosecute them on the basis of their cyber laws and regulations if they are found guilty.
In 2011, researchers estimated the energy used by the Internet to be between 170 and 307 GW, less than two percent of the energy used by humanity. This estimate included the energy needed to build, operate, and periodically replace the estimated 750 million laptops, a billion smart phones and 100 million servers worldwide as well as the energy that routers, cell towers, optical switches, Wi-Fi transmitters and cloud storage devices use when transmitting Internet traffic.
