VNC
VNC (Virtual Network Computing) 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. 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 is platform-independent, with clients and servers for many GUI-based operating systems and for Java. Multiple clients may connect to a VNC server at the same time. 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 VNC proper), etc. Many are compatible (without their added features) with VNC proper in the sense that a viewer of one flavour can connect with a server of another; others are based on VNC code but not compatible with st ...

RealVNC
RealVNC is a company that provides remote access software. Their VNC Connect software consists of a server (VNC Server) and client (VNC Viewer) application, which exchange data over the RFB protocol to allow the Viewer to control the Server's screen remotely. The application is used, for example, by IT support engineers to provide helpdesk services to remote users. History Andy Harter and other members of the original VNC team at AT&T founded RealVNC Limited in 2002. The automotive division of RealVNC spun out as a separate companyVNC Automotive in 2018. Platforms, editions, versions For a desktop-to-desktop connection RealVNC runs on Windows, macOS, and many Unix-like operating systems. A list of supported platforms can be found on thwebsite A RealVNC client also runs on the Java platform and on the Apple iPhone, iPod touch and iPad and Google Google LLC (, ) is an American multinational corporation and technology company focusing on online advertising, search engin ...

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, the X Window System and Wayland. 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 additiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Headless System
A headless computer is a computer system or device that has been configured to operate without a monitor (the missing "head"), Keyboard (computing), keyboard, and mouse (computing), 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) Personal computer, 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 (computing), 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.

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. Earlier history Quentin was e ...

Communications Protocol
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics (computer science), semantics, and synchronization of communication and possible Error detection and correction, error recovery methods. Protocols may be implemented by Computer hardware, hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses predetermined for that particular situation. The specified behavior is typically independent of how it is to be Implementation, implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there ...

Client (computing)
is a computer that gets information from another computer called server in the context of client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network. A client is a program that, as part of its operation, relies on sending a request to another program or a computer hardware or software that accesses a service made available by a server (which may or may not be located on another computer). For example, web browsers are clients that connect to web servers and retrieve web pages for display. Email clients retrieve email from mail servers. Online chat uses a variety of clients, which vary on the chat protocol being used. Multiplayer video games or online video games may run as a client on each computer. The term "client" may also be applied to computers or devices that run the client software or users that use the client software. A client is part of a cl ...

Server (computing)
A server is a computer that provides information to other computers called " clients" on a computer network. 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 computations 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 acknowledgment.
