Query: What does HTTPS stand for?
Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP) for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS), or, formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is therefore also often referred to as HTTP over TLS, or HTTP over SSL.
Aaron Greenspan created a web portal as a Harvard undergraduate called houseSYSTEM that launched in August 2003. In February 2004, when thefacebook.com launched, Greenspan recognized aspects of his own work in the site, and later came to believe that Zuckerberg was copying his work one feature at a time—a claim that Zuckerberg denied. Regarding Greenspan's allegations, Zuckerberg was described in "The New York Times" as "saying through a spokeswoman that he was not sure how to respond". Greenspan's company filed a Petition to Cancel the "Facebook" trademark, which included claims of prior use and fraud by Facebook, Inc. against the USPTO. Facebook, Inc. agreed to a formal settlement with Greenspan in late May 2009 and issued a press release, but the terms were not disclosed.
Encryption has long been used by militaries and governments to facilitate secret communication. It is now commonly used in protecting information within many kinds of civilian systems. For example, the Computer Security Institute reported that in 2007, 71% of companies surveyed utilized encryption for some of their data in transit, and 53% utilized encryption for some of their data in storage. Encryption can be used to protect data "at rest", such as information stored on computers and storage devices (e.g. USB flash drives). In recent years, there have been numerous reports of confidential data, such as customers' personal records, being exposed through loss or theft of laptops or backup drives; encrypting such files at rest helps protect them if physical security measures fail. Digital rights management systems, which prevent unauthorized use or reproduction of copyrighted material and protect software against reverse engineering (see also copy protection), is another somewhat different example of using encryption on data at rest.
WhatsApp was founded by Jan Koum and Brian Acton.WhatsApp joined Facebook in 2014, but continues to operate as a separate app with a laser focus on building a messaging service that works fast and reliably anywhere in the world.WhatsApp started as an alternative to SMS. Whatsapp now supports sending and receiving a variety of media including text, photos, videos, documents, and location, as well as voice calls. Whatsapp messages and calls are secured with end-to-end encryption, meaning that no third party including WhatsApp can read or listen to them. Whatsapp has a customer base of 1 billion people in over 180 countries. It is used to send personalised promotional messages to individual customers. It has plenty of advantages over SMS that includes ability to track how Message Broadcast Performs using blue tick option in Whatsapp. It allows sending messages to Do Not Disturb(DND) customers. Whatsapp is also used to send a series of bulk messages to their targeted customers using broadcast option. Companies started using this to a large extent because it is a cost effective promotional option and quick to spread a message. Still, Whatsapp doesn't allow businesses to place ads in their app.
The HTML5 specification introduced the video element for the purpose of playing videos, partially replacing the object element. HTML5 video is intended by its creators to become the new standard way to show video on the web, instead of the previous de facto standard of using the proprietary Adobe Flash plugin, though early adoption was hampered by lack of agreement as to which video coding formats and audio coding formats should be supported in web browsers.
"Share" uses encryption to hide the identity of who is transferring or what they are transferring. It is non-centralized so it cannot be easily shut down and it supports multiple source "swarm" downloading. All files are transferred encrypted so they must be decrypted upon download completion. In the meantime they are stored in encrypted form in a "Cache" folder. This folder is also used to allow recently downloaded files to be shared among the network based on priorities.
In the late 1980s, Berners-Lee, then a scientist at CERN, invented the World Wide Web to meet the demand for simple and immediate information-sharing among physicists working at CERN and different universities or institutes all over the world.
It provided an explanation of what the World Wide Web was, and how people could use a browser and set up a web server, as well as how to get started with your own website. In a list of 80 cultural moments that shaped the world, chosen by a panel of 25 eminent scientists, academics, writers, and world leaders, the invention of the World Wide Web was ranked number one, with the entry stating, "The fastest growing communications medium of all time, the internet has changed the shape of modern life forever. We can connect with each other instantly, all over the world".
The World Wide Web Virtual Library was the first index of content on the World Wide Web and still operates as a directory of e-texts and information sources on the web. It was started by Tim Berners-Lee creator of HTML and the World Wide Web itself, in 1991 at CERN in Geneva. Unlike commercial index sites, it is run by a loose confederation of volunteers, who compile pages of key links for particular areas in which they are expert. It is sometimes informally referred to as the "WWWVL", the "Virtual Library" or just "the VL".
At the close the larger house was raised to reveal Tim Berners-Lee working at a NeXT Computer, like the one on which he invented the World Wide Web. He tweeted 'This is for everyone', instantly spelled out in LED lights around the stadium. The programme explained "Music connects us with each other and with the most important moments in our lives. One of the things that makes those connections possible is the World Wide Web". Boyle wanted to honour Berners-Lee for having made the World Wide Web free and available to everyone (hence the tweet), rather than seeking a commercial profit from it.
Today, these two versions of the Internet Protocol are in simultaneous use. Among other technical changes, each version defines the format of addresses differently. Because of the historical prevalence of IPv4, the generic term "IP address" typically still refers to the addresses defined by IPv4. The gap in version sequence between IPv4 and IPv6 resulted from the assignment of version 5 to the experimental Internet Stream Protocol in 1979, which however was never referred to as IPv5.
Academics working at the university include Sir Tim Berners-Lee, inventor of the World Wide Web, Wendy Hall, inventor of Microcosm (hypermedia system) a predecessor of the World Wide Web, founding director of the Web Science Trust between the University of Southampton and MIT, José Antonio Bowen, President of Goucher College and a Fellow of the Royal Society of Arts, Erich Zepler, who made leading contributions to radio receiver development, David Payne, who invented EDFA for use in fibre optics cables, Sir Barry Cunliffe, a pioneer of modern British archaeology, Ray Monk, the biographer of Ludwig Wittgenstein, Albie Sachs, former Judge of the Constitutional Court of South Africa, and Tim Holt, former President of the Royal Statistical Society and Office for National Statistics.
Netflix supports HTML5 video using EME with a supported web browser: Chrome, Firefox, Microsoft Edge, Internet Explorer (on Windows 8.1 or newer), or Safari (on OS X Yosemite or newer). YouTube supports the HTML5 MSE. Available players supporting MPEG-DASH using the HTML5 MSE and EME are NexPlayer, THEOplayer by OpenTelly, the bitdash MPEG-DASH player, dash.js by DASH-IF or rx-player.
The structure and appearance of a web page is described by a combination of two standardized languages:
However, most older web browsers either did not fully implement the specifications for these languages or were developed prior to the finalization of the specifications (Microsoft Internet Explorer version 5.0 for the Macintosh platform, released in 2000, was the first major web browser with full support for CSS Level 1, for example). As a result, many older web pages were constructed to rely upon the older browsers' incomplete or incorrect implementations, and will only render as intended when handled by such a browser.
However, the Internet was not designed for anonymity: IP addresses serve as virtual mailing addresses, which means that any time any resource on the Internet is accessed, it is accessed from a particular IP address, and the data traffic patterns to and from IP addresses can be intercepted, monitored, and analysed, even if the content of that traffic is encrypted. This address can be mapped to a particular Internet Service Provider (ISP), and this ISP can then provide information about what customer that IP address was leased to. This does not necessarily implicate a specific individual (because other people could be using that customer's connection, especially if the customer is a public resource, such as a library), but it provides regional information and serves as powerful circumstantial evidence.
Previously, viewing YouTube videos on a personal computer required the Adobe Flash Player plug-in to be installed in the browser. In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the HTML5 standard. This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed. The YouTube site had a page that allowed supported browsers to opt into the HTML5 trial. Only browsers that supported HTML5 Video using the MP4 (with H.264 video) or WebM (with VP8 video) formats could play the videos, and not all videos on the site were available.
The adaptive bitrate streaming standard MPEG-DASH can be used in Web browsers via the HTML5 Media Source Extensions (MSE) and JavaScript-based DASH players. Such players are, e.g., the open-source project dash.js of the DASH Industry Forum, but there are also products such as bitdash of bitmovin (using HTML5 with JavaScript, but also a Flash-based DASH players for legacy Web browsers not supporting the HTML5 MSE).
The British intelligence agency Government Communications Headquarters (GCHQ)'s secret mass surveillance program Optic Nerve and National Security Agency (NSA) were reported to be indiscriminately collecting still images from Yahoo webcam streams from millions of mostly innocent Yahoo webcam users, among other things creating a database for facial recognition for future use. Optic Nerve took a still image from the webcam stream every 5 minutes.
The first one-way encryptions were likely developed by James H. Ellis, Clifford Cocks, and Malcolm Williamson at the UK intelligence agency GCHQ during the 1960s and 1970s and were published independently by Diffie and Hellman in 1976 (History of cryptography). Common modern one-way encryption algorithms, including MD5 (message digest) and SHA-512 (secure hash algorithm) are similar to the first such algorithms in that they also contain no mechanism to disclose the original data. The output of these modern one-way encryptions offer high privacy but are not homomorphic, meaning that the results of the one-way encryptions do not allow high order math operations (such as match). For example, we cannot use two SHA-512 sums to compare the closeness of two encrypted documents. This limitation makes it impossible for these one-way encryptions to be used to support classifying models in machine learning—or nearly anything else.
Web navigation came about with the introduction of the World Wide Web, in 1989 when Timothy Berners-Lee invented it. Once the world wide web was available, web navigation increasingly became a major aspect and role in jobs and everyday lives. With one-third of the world’s population now using the internet, web navigation maintains a global use in today's ever evolving international society. Web navigation is not restricted to just computers, either, as mobile phones and tablets have added avenues for access to the ever-growing information on the web today. The most recent wave of technology which has affected web navigation is the introduction and growth of the smartphone. As of January 2014, 58% of American adults owned a smart phone, and that number is on the rise from previous years. Web navigation has evolved from a restricted action, to something that many people across the world now do on a daily basis.
The Internet Protocol is the protocol that defines and enables internetworking at the Internet Layer and thus forms the Internet. It uses a logical addressing system. IP addresses are not tied in any permanent manner to hardware identifications and, indeed, a network interface can have multiple IP addresses. Hosts and routers need additional mechanisms to identify the relationship between device interfaces and IP addresses, in order to properly deliver an IP packet to the destination host on a link. The Address Resolution Protocol (ARP) performs this IP-address-to-hardware-address translation for IPv4. (A hardware address is also called a MAC address.) In addition, the reverse correlation is often necessary. For example, when an IP host is booted or connected to a network it needs to determine its IP address, unless an address is preconfigured by an administrator. Protocols for such inverse correlations exist in the Internet Protocol Suite. Currently used methods are Dynamic Host Configuration Protocol (DHCP), Bootstrap Protocol (BOOTP) and, infrequently, reverse ARP.
Ĥ or ĥ is a consonant in Esperanto orthography, representing a voiceless velar fricative or voiceless uvular fricative . Its name in Esperanto is "ĥo" (pronounced ).
X̂ is the Latin letter "X" with a circumflex. The letter is used in the Haida language and Aleut languages of Alaska.
HTTP defines methods (sometimes referred to as "verbs", but nowhere in the specification does it mention "verb", nor is OPTIONS or HEAD a verb) to indicate the desired action to be performed on the identified resource. What this resource represents, whether pre-existing data or data that is generated dynamically, depends on the implementation of the server. Often, the resource corresponds to a file or the output of an executable residing on the server. The HTTP/1.0 specification defined the GET, POST and HEAD methods and the HTTP/1.1 specification added five new methods: OPTIONS, PUT, DELETE, TRACE and CONNECT. By being specified in these documents, their semantics are well-known and can be depended on. Any client can use any method and the server can be configured to support any combination of methods. If a method is unknown to an intermediate, it will be treated as an unsafe and non-idempotent method. There is no limit to the number of methods that can be defined and this allows for future methods to be specified without breaking existing infrastructure. For example, WebDAV defined 7 new methods and specified the PATCH method.
