Comet (programming)
Comet is a web application model in which a long-held HTTPS request allows a web server to push data to a browser, without the browser explicitly requesting it. ''Comet'' is an umbrella term, encompassing multiple techniques for achieving this interaction. All these methods rely on features included by default in browsers, such as JavaScript, rather than on non-default plugins. The Comet approach differs from the original model of the web, in which a browser requests a complete web page at a time. The use of Comet techniques in web development predates the use of the word ''Comet'' as a neologism for the collective techniques. Comet is known by several other names, including ''Ajax Push'', ''Reverse Ajax'', ''Two-way-web'', ''HTTP Streaming'', and '' HTTP server push'' among others. The term ''Comet'' is not an acronym, but was coined by Alex Russell in his 2006 blog post. In recent years, the standardisation and widespread support of WebSocket and Server-sent events has render ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Application
A web application (or web app) is application software that is created with web technologies and runs via a web browser. Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages. Web applications are commonly distributed via a web server. There are several different tier systems that web applications use to communicate between the web browsers, the client interface, and server data. Each system has its own uses as they function in different ways. However, there are many security risks that developers must be aware of during development; proper measures to protect user data are vital. Web applications are often constructed with the use of a web application framework. Single-page applications (SPAs) and progressive web apps (PWAs) are two architectural approaches to creating web applications that provide a user experience similar to native apps, including features such as smoo ...

Blog
A blog (a Clipping (morphology), truncation of "weblog") is an informational website consisting of discrete, often informal diary-style text entries also known as posts. Posts are typically displayed in Reverse chronology, reverse chronological order so that the most recent post appears first, at the top of the web page. In the 2000s, blogs were often the work of a single individual, occasionally of a small group, and often covered a single subject or topic. In the 2010s, multi-author blogs (MABs) emerged, featuring the writing of multiple authors and sometimes professionally Editing, edited. MABs from newspapers, other News media, media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog Web traffic, traffic. The rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media. ''Blog'' can also be used as a verb, meaning ''to maintain or add content to a blog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Netscape
Netscape Communications Corporation (originally Mosaic Communications Corporation) was an American independent computer services company with headquarters in Mountain View, California, and then Dulles, Virginia. Its Netscape web browser was once dominant but lost to Internet Explorer and other competitors in the first browser war, with its market share falling from more than 90 percent in the mid-1990s to less than one percent in 2006. An early Netscape employee, Brendan Eich, created the JavaScript programming language, the most widely used language for client-side scripting of web pages. A founding engineer of Netscape, Lou Montulli, created HTTP cookies. The company also developed SSL which was used for securing online communications before its successor TLS took over. Netscape stock traded from 1995 until 1999 when the company was acquired by AOL in a pooling-of-interests transaction ultimately worth US$10 billion.

Silicon Valley
Silicon Valley is a region in Northern California that is a global center for high technology and innovation. Located in the southern part of the San Francisco Bay Area, it corresponds roughly to the geographical area of the Santa Clara Valley. The term "Silicon Valley" refers to the area in which high-tech business has proliferated in Northern California, and it also serves as a general metonymy, metonym for California's high-tech business sector. The cities of Sunnyvale, California, Sunnyvale, Mountain View, California, Mountain View, Palo Alto, California, Palo Alto and Menlo Park, California, Menlo Park are frequently cited as the birthplace of Silicon Valley. Other major Silicon Valley cities are San Jose, California, San Jose, Santa Clara, California, Santa Clara, Redwood City, California, Redwood City and Cupertino, California, Cupertino. The San Jose Metropolitan Area has the third-highest GDP per capita in the world (after Zürich, Switzerland, and Oslo, Norway), accor ...

Lightstreamer
Lightstreamer is a web-based asynchronous messaging project, implementing the WebSocket protocol, the Comet model, the push technology paradigm, and the real-time web practices. Origin The first version of Lightstreamer was created at the end of 2000, as one of the first attempts to implement real-time data push to HTML pages without employing Java applets. The application domain driving most of the interest in push technology at that time was market data distribution for the financial services industry. In the following years, Lightstreamer was used within other application domains too, including aerospace telemetry, where NASA chose Lightstreamer to push live telemetry data for the International Space Station. Architecture The Lightstreamer Server is a high-performance engine that manages all the connections with the clients through the Internet. It integrates with the backend systems via custom adapters. The Data Adapter receives the real-time data flow from the data feed and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pushlets
Push technology, also known as server Push, refers to a communication method, where the communication is initiated by a server rather than a client. This approach is different from the "pull" method where the communication is initiated by a client. In push technology, clients can express their preferences for certain types of information or data, typically through a process known as the publish–subscribe model. In this model, a client "subscribes" to specific information channels hosted by a server. When new content becomes available on these channels, the server automatically sends, or "pushes," this information to the subscribed client. Under certain conditions, such as restrictive security policies that block incoming HTTP requests, push technology is sometimes simulated using a technique called polling. In these cases, the client periodically checks with the server to see if new information is available, rather than receiving automatic updates. General use Synchronous co ...

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military.

Transmission Control Protocol
The Transmission Control Protocol (TCP) is one of the main communications protocol, protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliability (computer networking), reliable, ordered, and error detection and correction, error-checked delivery of a reliable byte stream, stream of octet (computing), octets (bytes) between applications running on hosts communicating via an IP network. Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP, which is part of the transport layer of the TCP/IP suite. Transport Layer Security, SSL/TLS often runs on top of TCP. TCP is Connection-oriented communication, connection-oriented, meaning that sender and receiver firstly need to establish a connection based on agreed parameters; they do this through three-way Ha ...
