Zero Client Introduction

A zero-client is an I/O redirector device that allows a full cluster of peripheral devices to be deployed at the desired point of service without a dedicated PC or thin client at that same location and without requiring any modifications to existing software applications. Zero-clients are network-based and contain interfaces for a variety of peripheral device types including VGA and other video monitor interfaces, serial, USB and optionally others such as audio or PS/2. The zero-client contains network protocols, allowing each of these interface types to be supported over a wired or wireless IP network without a local PC or thin client. They are connected over the network to applications running on a PC or server elsewhere on the IP network. Zero-clients may run in two modes: standard remote device mode or terminal emulation mode. Remote device mode allows remote peripherals to connect to applications running on PCs elsewhere on the network. Terminal emulation mode allows the zero-client and standard devices such as printers and keyboards to replace legacy terminals.
