It is used by providers such aVPChatanand eventually evolved into Lotus Sametime. Virtual Places requires a server and client software. Users start Virtual Places along with a web browser and sign into the Virtual Places server. Avatars are overlaid onto the web browser and users are able to collaborate with each other while they all visit web sites in real time. Some Virtual Places consumer-oriented communities are still alive on the Web and are using the old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real-time Computing
Real-time computing (RTC) is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response. Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines". Ben-Ari, Mordechai; "Principles of Concurrent and Distributed Programming", ch. 16, Prentice Hall, 1990, , page 164 Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds. A system not specified as operating in real time cannot usually ''guarantee'' a response within any timeframe, although ''typical'' or ''expected'' response times may be given. Real-time processing ''fails'' if not completed within a specified deadline relative to an event; deadlines must always be met, regardless of system load. A real-time system has been described as one which "controls an environment by receiving data, processing them, and returning the results sufficiently quic ...

Software Companies Of Israel
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Session Initiation Protocol
The Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating communication sessions that include voice, video and messaging applications. SIP is used in Internet telephony, in private IP telephone systems, as well as mobile phone calling over LTE (VoLTE). The protocol defines the specific format of messages exchanged and the sequence of communications for cooperation of the participants. SIP is a text-based protocol, incorporating many elements of the Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP). A call established with SIP may consist of multiple media streams, but no separate streams are required for applications, such as text messaging, that exchange data as payload in the SIP message. SIP works in conjunction with several other protocols that specify and carry the session media. Most commonly, media type and parameter negotiation and media setup are performed with the Session Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lotus Software
Lotus Software (called Lotus Development Corporation before its acquisition by IBM) was an American software company based in Massachusetts; it was "offloaded" to India's HCL Technologies in 2018. Lotus is most commonly known for the Lotus 1-2-3 spreadsheet application, the first feature-heavy, user-friendly, reliable and WYSIWYG-enabled product to become widely available in the early days of the IBM PC, when there was no graphical user interface. Much later, in conjunction with Ray Ozzie's Iris Associates, Lotus also released a groupware and email system, Lotus Notes. IBM purchased the company in 1995 for US$3.5 billion, primarily to acquire Lotus Notes and to establish a presence in the increasingly important client–server computing segment, which was rapidly making host-based products such as IBM's OfficeVision obsolete. On December 6, 2018, IBM announced the sale of Lotus Software/Domino to HCL for $1.8 billion. History Lotus was founded in 1982 by partners Mitch ...

Global Network Navigator
The Global Network Navigator (GNN) was the first commercial web publication and the first web site to offer clickable advertisements. GNN was launched in May 1993, as a project of the technical publishing company O'Reilly Media, then known as O'Reilly & Associates. In June 1995, GNN was sold to AOL, which continued its editorial functions while converting it to a dial-up Internet Service Provider. AOL closed GNN in December 1996, moving all GNN subscribers to the AOL dial-up service. As a web portal History In September 1992, O'Reilly & Associates published the ''Whole Internet User's Guide and Catalog''. The company then created an online version using ViolaWWW, a web browser that introduced enhanced HTML features such as formatting, graphics, scripting, and embedded applets, and demonstrated a kiosk version that was deployed briefly at the Computer Literacy Bookshop in late 1992. In February 1993, the company's CEO, Tim O'Reilly, authorized a four-person "skunkworks" team, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
America Online
AOL (stylized as Aol., formerly a company known as AOL Inc. and originally known as America Online) is an American web portal and online service provider based in New York City. It is a brand marketed by the current incarnation of Yahoo! Inc. The service traces its history to an online service known as PlayNET. PlayNET licensed its software to Quantum Link (Q-Link), who went online in November 1985. A new IBM PC client launched in 1988, eventually renamed as America Online in 1989. AOL grew to become the largest online service, displacing established players like CompuServe and The Source. By 1995, AOL had about three million active users. AOL was one of the early pioneers of the Internet in the mid-1990s, and the most recognized brand on the web in the United States. It originally provided a dial-up service to millions of Americans, pioneered instant messaging, and in 1993 began adding internet access. In 1998, AOL purchased Netscape for $4.2 billion. In 2001, at the height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed Computing
A distributed system is a system whose components are located on different computer network, networked computers, which communicate and coordinate their actions by message passing, passing messages to one another from any system. Distributed computing is a field of computer science that studies distributed systems. The components of a distributed system interact with one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming the clock synchronization, lack of a global clock, and managing the independent failure of components. When a component of one system fails, the entire system does not fail. Examples of distributed systems vary from service-oriented architecture, SOA-based systems to massively multiplayer online games to peer-to-peer, peer-to-peer applications. A computer program that runs within a distributed system is called a distributed program, and ''distributed programming' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instant Messaging
Instant messaging (IM) technology is a type of online chat allowing real-time text transmission over the Internet or another computer network. Messages are typically transmitted between two or more parties, when each user inputs text and triggers a transmission to the recipient(s), who are all connected on a common network. It differs from email in that conversations over instant messaging happen in real-time (hence "instant"). Most modern IM application (computing), applications (sometimes called "social messengers", "messaging apps" or "chat apps") use push technology and also add other features such as emojis (or graphical smileys), file transfer, chatbots, voice over IP, or Videotelephony, video chat capabilities. Instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a "buddy list" or "friend list"), and can be standalone applications or integrated into e.g. a wider social media platform, or a website ...

Avatar (computing)
In computing, an avatar is a graphical representation of a user or the user's character or persona. Avatars can be two-dimensional icons in Internet forums and other online communities, where they are also known as profile pictures, userpics, or formerly picons (personal icons). Alternatively, an avatar can take the form of a three-dimensional model, as used in online worlds and video games. The term ' () originates from Sanskrit, and was adopted by early computer games and science fiction novelists. Richard Garriott extended the term to an on-screen user representation in 1985, and the term gained wider adoption in Internet forums and MUDs. Nowadays, avatars are used in a variety of online settings including social media, virtual assistants, instant messaging platforms, and digital worlds such as ''World of Warcraft'' and ''Second Life''. They can take the form of an image of one's real-life self, as often seen on platforms like Facebook, or a virtual character that diverge ...
