Internet Definition and 10 Discussions

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia in the 1980s, commercialization incorporated its services and technologies into virtually every aspect of modern life.
Most traditional communication media, including telephony, radio, television, paper mail and newspapers are reshaped, redefined, or even bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, and video streaming websites. Newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking services. Online shopping has grown exponentially for major retailers, small businesses, and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or even sell goods and services entirely online. Business-to-business and financial services on the Internet affect supply chains across entire industries.
The Internet has no single centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own policies. The overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Today's list of New Seven Wonders.

    Mobile network or internet on Long-Fi?

    I have a question if it would be possible to have a cellular network on Long-Fi? I have tried searching for information on the theoretical maximum bandwidth of Long-Fi; but, can't find anything. I also am unsure if the idea would be of interest to companies like Tesla to set up a hub connecting...

    5G and future 6G terahertz absorbed by water vapour = heating?

    I just found this piece in an article: Terahertz waves (THz), which are submillimeter waves sitting between microwave and infrared light on the electromagnetic spectrum, have been used to achieve data rates greater than 100 Gbps. Unfortunately, THz waves share an Achilles’ Heel with the...

    A Using quantum-secured communication for data transfering

    Hello! I am wondering if it is theoretically possible to allow a means of data transfer (or internet, etc.) by the idea of quantum entanglement. Correct me if I make any errors in understanding. But, by what I understand, in essence you could for instance run a computation on a quantum computer...

    Skype Problem: Sorry, we couldn't connect to Skype

    The Skype application is a useful one. It allows you to connect to other people with Skype all around the world for free. Now that we have the formalities aside, allow me to state the problem I am having. Since I have two Skype accounts--one for my friends on games, the other for a personal...

    Explaining Telecommunication

    How telecommunications work? I mean, there are so much waves around us nowadays, how my cellphone recognizes a single signal and rings only when it detects it? If my cellphone is a receipter, why can't I listen to my neighbor converstation, why isn't there a lot of interference and how waves...

    Who is this Jess Brewer?

    Hi, I'm a retired (since 2011) Physics prof from the University of British Columbia. I originally set out to get a PhD in Physics to increase my credibility as a science fiction writer, but I discovered a field* that was so cool it was like being a character in my own SF novel. In short, I got...

    Windows Vista - Internet/Firewall doesn't work

    My sister just came into my room asking for help, when I came to her room she told me that her computer froze and she waited for 20 minutes for it to unstuck but it didn't and she turned it off, when she turned it on her Internet was not working and neither did her Firewall. I tried turning on...
