VNC
Virtual Network Computing (VNC) is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse input from one computer to another, relaying the graphical- screen updates, over a network. VNC is platform-independent – there are clients and servers for many GUI-based operating systems and for Java. Multiple clients may connect to a VNC server at the same time. Popular uses for this technology include remote technical support and accessing files on one's work computer from one's home computer, or vice versa. VNC was originally developed at the Olivetti & Oracle Research Lab in Cambridge, United Kingdom. The original VNC source code and many modern derivatives are open source under the GNU General Public License. There are a number of variants of VNC which offer their own particular functionality; e.g., some optimised for Microsoft Windows, or offering file transfer (not part of ...

RFB Protocol
RFB ("remote framebuffer") is an open simple protocol for remote access to graphical user interfaces. Because it works at the framebuffer level it is applicable to all windowing systems and applications, including Microsoft Windows, macOS and the X Window System. RFB is the protocol used in Virtual Network Computing (VNC) and its derivatives. Description By default, a viewer/client uses TCP port 5900 to connect to a server (or 5800 for browser access), but can also be set to use any other port. Alternatively, a server can connect to a viewer in "listening mode" (by default on port 5500). One advantage of listening mode is that the server site does not have to configure its firewall/NAT to allow access on the specified ports; the burden is on the viewer, which is useful if the server site has no computer expertise, while the viewer user would be expected to be more knowledgeable. Although RFB started as a relatively simple protocol, it has been enhanced with additional features ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andy Harter
Andrew Charles Harter (born 1961 in Yorkshire, England) is a British computer scientist, best known as the founder of RealVNC, where he was CEO until March 2018. Education and early life Born in Yorkshire in 1961, Harter attended the Queen Elizabeth Grammar School, Wakefield.

Olivetti & Oracle Research Lab
The Olivetti Research Laboratory (ORL) was a research institute in the field of computing and telecommunications founded in 1986 by Hermann Hauser and Andy Hopper. History When Olivetti acquired Acorn Computers in 1985, Hauser, who was Acorn's co-founder, became vice-president for research at Olivetti where he was in charge of laboratories in the US and Europe. In 1986, Hauser co-founded the Olivetti Research Laboratory (ORL) in Cambridge, England, along with Professor Andy Hopper. Hopper became the laboratory's Director. In 1988, Hauser left Olivetti. In 1997 the lab became the Olivetti & Oracle Research Lab. In January 1999 it was acquired by AT&T Corporation and became AT&T Laboratories Cambridge. AT&T Laboratories Cambridge was for three years Europe's leading communications engineering research laboratory. The laboratory was internationally recognised as a centre of excellence, undertaking advanced research into communications, multimedia and mobile technologies. As a resul ...

Quentin Stafford-Fraser
James Quentin Stafford-Fraser is a computer scientist and entrepreneur based in Cambridge, England. He was one of the team that created the first webcam, the Trojan room coffee pot. Quentin pointed a camera at the coffee pot and wrote the XCoffee client program which allowed the image of the pot to be displayed on a workstation screen. When web browsers gained the ability to display images, the system was modified to make the coffee pot images available over HTTP and thus became the first webcam. Quentin wrote the original VNC client (viewer) and server for the Windows operating system, while at the Olivetti Research Laboratory. He is a regular public speaker and his work has attracted significant media coverage. Quentin is also a part-time Senior Research Associate at the University of Cambridge Computer Lab. In 2013 he was a member of the winning team on ''Christmas University Challenge'', representing Gonville & Caius College, Cambridge. Companies founded Quentin has f ...

Headless System
A headless computer is a computer system or device that has been configured to operate without a monitor (the missing "head"), keyboard, and mouse. A headless system is typically controlled over a network connection, although some headless system devices require a serial connection to be made over RS-232 for administration of the device. Headless operation of a server is typically employed to reduce operating costs. PC BIOS limitations During bootup, some (especially older) PC BIOS versions will wait indefinitely for a user to press a key before proceeding. If some basic device, such as a video card or keyboard, are not installed or connected, this could effectively halt an unattended system. On more modern systems, the BIOS factory setting will typically be configured to behave this way as well, but this setting can be changed with a BIOS setup utility to proceed without user intervention. Even in cases where a system has been set up to be managed remotely, a local keyboard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Computer
The Network Computer (or NC) was a diskless desktop computer device made by Oracle Corporation from about 1996 to 2000. The devices were designed and manufactured by an alliance, which included Sun Microsystems, IBM, and others. The devices were designed with minimum specifications, based on the Network Computer Reference Profile. The brand was also employed as a marketing term to try to popularize this design of computer within enterprise and among consumers. The NC brand was mainly intended to inspire a range of desktop computers from various suppliers that, by virtue of their diskless design and use of inexpensive components and software, were cheaper and easier to manage than standard fat client desktops. However, due to the commoditization of standard desktop components, and due to the increasing availability and popularity of various software options for using full desktops as diskless nodes, thin clients, and hybrid clients, the Network Computer brand never achieved t ...

Server (computing)
In computing, a server is a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called " clients". This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledg ...

Thin Client
In computer networking, a thin client is a simple (low-performance) computer that has been optimized for establishing a remote connection with a server-based computing environment. They are sometimes known as ''network computers'', or in their simplest form as ''zero clients''. The server does most of the work, which can include launching software programs, performing calculations, and storing data. This contrasts with a rich client or a conventional personal computer; the former is also intended for working in a client–server model but has significant local processing power, while the latter aims to perform its function mostly locally. Thin clients occur as components of a broader computing infrastructure, where many clients share their computations with a server or server farm. The server-side infrastructure uses cloud computing software such as application virtualization, hosted shared desktop (HSD) or desktop virtualization (VDI). This combination forms what is know ...
