Instead of an operating system, Zero Clients have a highly tuned onboard processor specifically designed for one possibly three VDI protocols (PCoIP, HDX, or RemoteFX). Most of the decoding and display processes take place in dedicated hardware and therefore are more efficient than using a software client and a standard CPU and GPU setup as with a Thin Client. Zero Clients have boot up speeds of just a few seconds and are immune to viruses, decreasing the overall downtime of the device and increasing the productivity to the end-user. The Zero Client device requires very little maintenance and rarely needs an update unless there is a significant change/enhancement to the VDI protocol or the occasional BIOS related update.
Thinvent has its own Zero client named Micro 2. For more information, click on the link below.
