U.S. Army soldiers "surfing the Internet" at Forward Operating Base Yusifiyah, Iraq The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is a network of networks[1] that consists of millions 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 an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks for file sharing and telephony. Most traditional communications media, including telephony and television, are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV).

Devices in schools and at home means too much screen time for kids Since the 2008 “Digital Education Revolution”, when the government funded laptops for secondary school students, there has been a growing impetus to increase young people’s screen time both in school and for homework at home. Now that the government funding has ceased, schools are moving toward “Bring Your Own Device” policies so that students can continue to benefit from educative uses of modern computing devices. Continuing to advance our students’ IT skills is an educational priority. IT skills are one of the key “General Capabilities” in the national curriculum and also appear in the content descriptions for specific subjects. In recent times there has been increasing interest in international comparisons through tests such as the International Computer and Information Literacy Study. It is likely that school-provided or self-provided device programs greatly increase students’ screen time both at school and at home.

Category: Internet.en The Internet is the publicly available worldwide system of interconnected computer networks that transmit data by packet switching over the Internet Protocol (IP). It is made up of thousands of other, smaller business, academic, and government networks. The terms Internet and World Wide Web are often used in every-day speech without much distinction. However, the Internet and the World Wide Web are not one and the same. The Internet is a global data communications system. XML Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification[2] and by several other related specifications,[3] all of which are free open standards.[4] The design goals of XML emphasize simplicity, generality and usability across the Internet.[5] It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, it is widely used for the representation of arbitrary data structures[6] such as those used in web services. Several schema systems exist to aid in the definition of XML-based languages, while many application programming interfaces (APIs) have been developed to aid the processing of XML data. Applications of XML[edit]

All About The Internet: Infrastructure Infrastructure description Computer Networking: Global Infrastructure for the 21st Century By Vint Cerf Administration Psychedelic experience A "psychedelic experience" is an altered state of awareness induced by the consumption of certain psychotropics, holotropic breathwork, meditation, or sensory deprivation.[citation needed] Definition[edit] The definition of "psychedelic experience" is characterized by polyvalence or ambiguity due to its nature. In modern psychopharmacological science as well as philosophical, psychological, neurological, spiritual-religious and most other ideological discourses it is understood as an altered state of awareness often distinct to, and induced by the consumption of certain psychotropics. Psychedelic compounds are known to cause this change in mental state.

Cyberbullying: From playground to Internet Watch a school playground and you might not see signs of bullying. But bullying is happening more than ever, mostly within the digital network of cyberspace. It’s called cyberbullying and according to Nearly half of young people have experienced some form of cyberbullying, and 10 to 20 percent experience it regularly.Mean, hurtful comments and gossip are the most common types of cyberbullying, and in cyberspace they can circulate widely in just minutes.Girls are at least as likely as boys to be cyberbullies or be victimized.Boys are more likely to be threatened by cyberbullies than girls.Cyberbullying victims are more likely to have low self-esteem and consider suicide. Recognize cyberbullying symptoms “Cyberbullies do their bullying through text messaging and social media such as Facebook,” said Wendy Chryst, a clinical social worker at Marshfield Clinic who sees mostly adolescents.

HTML HTML or HyperText Markup Language is the standard markup language used to create web pages. HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>). HTML tags most commonly come in pairs like <h1>and </h1>, although some tags represent empty elements and so are unpaired, for example <img>. The first tag in a pair is the start tag, and the second tag is the end tag (they are also called opening tags and closing tags). The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages. How Internet Infrastructure Works" One of the greatest things about the Internet is that nobody really owns it. It is a global collection of networks, both big and small. These networks connect together in many different ways to form the single entity that we know as the Internet. In fact, the very name comes from this idea of interconnected networks.

Eight-circuit model of consciousness The eight-circuit model of consciousness is a theory proposed by Timothy Leary and expanded on by Robert Anton Wilson and Antero Alli. The model describes eight circuits of information (eight "brains") that operate within the human nervous system. Each circuit is concerned with a different sphere of activity. Leary, Alli and Wilson have written about the model in depth and how each circuit operates, both in the lives of individual people and in societies. The term "circuits" came from the first wave of cybernetics research and development in the United States in the 1970s. (Others[weasel words] have proposed that the term "systems" should be substituted for "circuits" to reflect both a systems theory approach and also the changing anatomy of an entity as it goes through a neurological change).

Cyber bullying: Father crusades to stop bullies after daughter's suicide following Facebook tirade Updated Michael Cleland was nervous — he had spoken to groups of people before, but he wanted this speech to make an impact, to change behaviour, to save lives. Students at Glenroy College in Melbourne's north thought they were in for a boring power-point presentation about cyber bullying — they had heard the warnings before, but never like this. World Wide Web The World Wide Web (abbreviated as WWW or W3,[3] commonly known as the web) is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them via hyperlinks. History[edit]

DRI: How Does The Internet Work? Introduction The Internet is a global network of computers which allows people to exchange data worldwide instantaneously. This simple sentence is the most accurate way to summarize the definition of "Internet," but it does not do justice to the phenomenal technology behind the Internet. Ichthyoallyeinotoxism Ichthyoallyeinotoxism, or hallucinogenic fish inebriation, comes from eating certain species of fish found in several parts of the tropics, the effects of which are reputed to be similar in some aspects to LSD. Experiences may include vivid auditory and visual hallucinations. This has given rise to the collective common name "dream fish" for ichthyoallyeinotoxic fish.
