Library staff use small embedded Linux or Windows boxes that run Horizon Client and a browser only. Which VDI client type is that?

Library staff boxes with embedded Linux or Windows that run Horizon Client and a browser only are thin clients—limited local OS plus client software. In municipal EUC terms, treat the endpoint as a window into city systems when the architecture says so, not as the system of record for the files or apps in the stem. Distractor concept: Zero client means firmware only with no local OS—these boxes have an OS. Distractor concept: Fat client means a full municipal desktop install, not a locked-down client-only appliance. Distractor concept: Unified Access Gateway is a DMZ access appliance, not the device on the library desk. Exam caveat: Little OS launching Horizon Client = thin; firmware-only = zero; full PC = fat. Operational check: Confirm the library units boot an embedded OS, launch Horizon Client locally, and are managed as thin endpoints. Record the chosen control and the rejected failure modes in the civic change ticket or runbook so on-call staff and auditors share the same rationale after the next maintenance window. Re-validate after personnel or image changes that the same control still meets the city's continuity, security, and support expectations for this service. Helpdesk coaching tip aligned to the conversational brief: If there is a little OS that launches Horizon Client, you are in thin-client land — a locked-down set-top, not a firmware puck and not a full staff PC. Zero means no OS at all. UAG is the DMZ gateway, not the device on the library desk.
