)A virtual keyboard is where a full-size image of a QWERTY keyboard is projected onto any surface. Touching the image of a key generates a unique electronic signal corresponding to a key’s image. Using a virtual keyboard eliminates the chance of breakage and infection transfer. Additionally virtual keyboards require no cleaning and they have no wires, buttons, or switches. Virtual keyboards are also compatible with many Smartphones and PDAs. A virtual keyboard is also called a projection keyboard. VKEY is the trademarked name of the virtual keyboard developed by Virtual Devices Inc.

- Virtual Machine
A self-contained operating environment that behaves as if it is a separate computer. For example, Java applets run in a Java virtual machine (VM) that has no access to the host operating system. This design has two advantages: System Independence: A Java application will run the same in any Java VM, regardless of the hardware […]
- virtual machine server
A virtual machine (VM) server hosts virtual machines running operating systems in one of two following modes: fully virtual: completely emulates all hardware devices paravirtual mode: does not require complete emulation of hardware devices.
- Virtual Memory
)(n.) An imaginary memory area supported by some operating systems (for example, Windows but not DOS) in conjunction with the hardware. You can think of virtual memory as an alternate set of memory addresses. Programs use these virtual addresses rather than real addresses to store instructions and data. When the program is actually executed, the […]
- virtual network computing
Through the use of software VNC, acronym for virtual network computing, makes it possible to interact with a computer from any computer or mobile device on the Internet. VNC software provides cross-platform support allowing remote control between different types of computers. To use VNC you must have a network TCP/IP connection, a VNC server and […]
- virtual printer
A file containing a set of attribute values that describe the data stream for a printer. Before a print job can be placed in a queue, a virtual printer definition must exist for both the print queue and the queue device.
