UltraVNC
UltraVNC (sometimes written uVNC) is an open-source remote-administration/ remote-desktop-software utility. The client supports Microsoft Windows and Linux but the server only supports Windows. It uses the VNC protocol to control/access another computer remotely over a network connection. Features UltraVNC allows the use of a remote computer as if the user were in front of it. This is achieved by sending mouse movements and key-presses to the remote computer, and replicating the remote computer's display (subject to differences in resolution) locally in real time. UltraVNC bears a strong resemblance to RealVNC Free Edition. However, in addition to remote control, it adds various features, such as an encryption plugin to secure the client/server connection. It also supports file transfers, chat functionality and various authentication methods. The two computers must be able to communicate across a network, such as a local subnet, internal network, or the Internet. The software ...

Comparison Of Remote Desktop Software
This page is a comparison of notable remote desktop software available for various platforms. Remote desktop software Operating system support Features Terminology In the table above, the following terminology is intended to be used to describe some important features: *Listening mode: where a server connects to a viewer. The server site does not have to configure its firewall/NAT to allow access on a defined port; the onus 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. *Built-in encryption: the software has at least one method of encryption, encrypting the data between the local and remote computers, and the encryption mechanism is built into the remote control software. *File transfer: the software allows the user to transfer files between the local and remote computers, from within the client software's user interface. *Audio support: the remote control software tr ...

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] |
Virtual Network Computing
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 V ...

Mirror Driver
A mirror driver is a display driver for a virtual device that mirrors the drawing operations of one or more additional physical display devices. When video mirroring is active, each time the system draws to the primary video device at a location inside the mirrored area, a copy of the draw operation is executed on the mirrored video device in real-time. Windows' mirror drivers were first introduced in 1998 with the Windows 2000 display driver model, which was renamed later to XPDM. In 2006, for Windows Vista, Microsoft introduced a new Windows Display Driver Model. The older drivers were still supported under Vista, but since the older model did not encompass support for features first introduced with Vista, those newer features would necessarily be disabled when an older driver was active. As a consequence, when a mirror driver designed for the older model was active, such as when Windows Remote Assistance or Windows Live Mesh were in use, Vista disabled Desktop Window Manager and ...

Release Candidate
A software release life cycle is the sum of the stages of development and maturity for a piece of computer software ranging from its initial development to its eventual release, and including updated versions of the released version to help improve the software or fix software bugs still present in the software. There are several models for such a life cycle. A common method is that suggested by Microsoft, which divides software development into five phases: Pre-alpha, Alpha, Beta, Release candidate, and Stable. Pre-alpha refers to all activities performed during the software project before formal testing. The alpha phase generally begins when the software is feature complete but likely to contain several known or unknown bugs. The beta phase generally begins when the software is deemed feature complete, yet likely to contain several known or unknown bugs. Software in the production phase will generally have many more bugs in it than completed software, as well as speed/performan ...

Portable Software
A portable application (portable app), sometimes also called standalone, is a program designed to read and write its configuration settings into an accessible folder in the computer, usually in the folder where the portable application can be found. This makes it easier to transfer the program with the user's preferences and data between different computers. A program that doesn't have any configuration options can also be a portable application. Portable applications can be stored on any data storage device, including internal mass storage, a file share, cloud storage or external storage such as USB drives and floppy disks—storing its program files and any configuration information and data on the storage medium alone. If no configuration information is required a portable program can be run from read-only storage such as CD-ROMs and DVD-ROMs. Some applications are available in both installable and portable versions. Some applications which are not portable by default do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Administration Software
In computing, the term remote desktop refers to a software- or operating system feature that allows a personal computer's desktop environment to be run remotely off of one system (usually a PC, but the concept applies equally to a server or a smartphone), while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration. Overview Remote access can also be explained as the remote control of a computer by using another device connected via the internet or another network. This is widely used by many computer manufacturers and large businesses help desks for technical troubleshooting of their customer's problems. Remote desktop software captures the mouse and keyboard inputs from the local computer (client) and sends them to the rem ...

Help Desk
A help desk is a department or person that provides assistance and information usually for electronic or computer problems. In the mid-1990s, research by Iain Middleton of Robert Gordon University studied the value of an organization's help desks. It found that value was derived not only from a reactive response to user issues, but also from the help desk's unique position of communicating daily with numerous customers or employees. Information gained in areas such as technical problems, user preferences, and satisfaction can be valuable for the planning and development work of other information technology units. Large help desks have a person or team responsible for managing the incoming requests, called "issues"; they are commonly called queue managers or queue supervisors. The queue manager is responsible for the issue queues, which can be set up in various ways depending on the help desk size or structure. Typically, large help desks have several teams that are experienced i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
