VNC Enterprise Edition是业界标准的VNC（Virtual Network Computing) 的增强版本，专为企业环境应用和穿越Internet而开发。它完全由VNC的最初发明者设计和开发，Enterprise Edition提供更好的稳定性和更容易管理的安全性。

VNC（Virtual Network Computing，虚拟网络计算）最早是一套由英国剑桥大学AT&T实验室在2002年开发的轻量型的远程控制计算机软件，其采用了 GPL 授权条款，任何人都可免费取得该软件。VNC软件主要由两个部分组成：VNC server及VNC viewer。用户需先将VNC server安装在被控端的计算机上后，才能在主控端执行 VNC viewer 控制被控端。

VNC server 与 VNC viewer 支持多种操作系统，如 windows，Linux，MacOS 及 Unix 系列（Unix，Solaris等），因此可将 VNC server 及 VNC viewer 分别安装在不同的操作系统中进行控制。RealVNC 的优越性还在于如果操作系统的主控端计算机没有安装 VNC viewer，也可以通过一般的网络浏览器（如 IE 等）来控制被控端（需要 Java 虚拟机的支持）。

整个 VNC 一般运行的工作流程如下：

（1） VNC 客户端通过浏览器或 VNC Viewer 连接至 VNC Server。

（2） VNC Server 传送一对话窗口至客户端，要求输入连接密码（可能为空），以及存取的 VNC Server 显示装置。

（3） 在客户端输入连接密码后，VNC Server 验证客户端是否具有存取权限。

（4） 若是客户端通过 VNC Server 的验证，客户端即要求 VNC Server 显示桌面环境。

（5） 被控端将画面显示控制权交由 VNC Server 负责。

（6） VNC Server 将把被控端的桌面环境利用 VNC 通信协议送至客户端，并且允许客户端控制 VNC Server 的桌面环境及输入装置。

RealVNC is a server and client application for the Virtual Network Computing (VNC) protocol to control another computer's screen remotely. RealVNC is produced by the company RealVNC Ltd., which was founded by the same AT&T team that created the original VNC program. RealVNC can be seen as a continuation of the original VNC program. RealVNC runs on Windows, Mac OS X (Enterprise edition only), and many Unix-like operating systems (Free & Enterprise editions only). There is also a RealVNC client which runs on the Java platform. There are beta versions of the Enterprise edition for Pocket PC and 'VNC-over-HTTP' tunnelling for Windows and Linux.

VNC has a wide range of applications including system administration, IT support and helpdesks. It can also be used to support the mobile user, both for hot desking within the enterprise and also to provide remote access at home, or on the road. The system allows several connections to the same desktop, providing an invaluable tool for collaborative or shared working in the workplace or classroom. Computer support within the geographically spread family is an ever popular use.

For the individual user, one common scenario is using VNC to help troubleshoot the computer of a distant less-technically-savvy relative. In other words, sitting at your desk in Baltimore, you could use VNC to take control of your relative's PC in California and show them how to install and use some new software package by actually doing it yourself.

A very common business application of VNC is in remote system administration, where it is used to allow administrators to take control of employee machines to diagnose and fix problems, or to access and administer server machines without making a trip to the console. VNC can also be used to provide a flexible hot-desking and road-warrior environment by allowing employees to access their office desktop and server machines from any machine in the company's offices or from other remote sites, regardless of the type of computers involved at either end.

VNC is widely used in educational contexts, for example to allow a distributed group of students simultaneously to view a computer screen being manipulated by an instructor, or to allow the instructor to take control of the students' computers to provide assistance. Of course, as these examples illustrate, the variety of uses of VNC is really as diverse as the many millions of VNC users.
