虚拟终端的输入输出设备：从计算机或网络接收虚拟终端的桌面，然后将虚拟终端的桌面通过视频输出端口单向发送出去；从鼠标、键盘信号接收端口接收鼠标、键盘信号，然后将鼠标、键盘信号发送给计算机。虚拟终端的输入输出设备不能（不）发送数据包给所述瘦客户机信号中转设备，所述虚拟终端的输入输出设备用向瘦客户机信号中转设备发送所述虚拟终端的桌面。
瘦客户机信号中转设备：从 视频输入端口 单向 接收虚拟终端的桌面，然后将虚拟终端的桌面发送给瘦客户机；从瘦客户机接收鼠标、键盘信号，然后通过鼠标、键盘信号发送端口将鼠标、键盘信号发送出去。
瘦客户机信号中转设备的视频信号输入端口通过视频线连接虚拟终端的输入输出设备的视频信号输出端口 ，常用的视频线是铜线、VGA线等，或者是其他类似的视频线，由于在传输视频时该视频线不传输数据包，阻止了数据泄密的可能性。
虚拟终端的输入输出设备往瘦客户机信号中转设备单向发送视频信号和音频信号，在此发送视频的过程中，不使用TCP/IP、telnet等网络协议。
每个瘦客户机都有一组瘦客户机信号中转设备的远程输入输出端口对应；
虚拟终端的输入输出设备的视频输出端口、鼠标信号输入端、键盘信号输入端口分别对应连接瘦客户机信号中转设备的的视频输入端口、鼠标信号输出端、键盘信号输出端口；瘦客户机信号中转设备的的视频输入端口、鼠标信号输出端、键盘信号输出端口是一组输入输出端口。
虚拟终端的输入输出设备有至少一组输入输出端口，虚拟终端连接虚拟终端的每组输入输出端口包括一个视频输出端口、一个鼠标输入端口和一个键盘输入端口。
