Term	Definition
ThinOS	Dell lightweight operating system for thin clients.
Enhanced Mode	A privileged ThinOS mode that enables App Builder, CI app support, and certificate-based security.
Appliance Mode	The default ThinOS mode is optimized for security but does not support CI applications.
Customer-Installed (CI) Application	A third-party or custom app that is packaged for ThinOS using .deb files or App Builder.
CI Apps Onboarding	Third‑party or custom .deb‑based application that is packaged for ThinOS that must be onboarded by Dell to run in Native Mode. CI Apps Onboarding is the required package that enables such applications to be created, allowlisted, and performed in Native Mode. Any application that is intended for Native Mode must be onboarded by Dell in advance, and once onboarding is complete, installing the CI Apps Onboarding package is sufficient to enable the application to run on ThinOS.
App Builder	A ThinOS feature for creating secure, deployable CI application packages. App Builder supports the following deployment modes: Isolated Mode—Runs apps in a secure, containerized environment. Prevents conflicts with ThinOS base OS. Native Mode—Runs apps directly on ThinOS OS with full system access. Higher risk of dependency conflicts and security exposure.
WMS (Wyse Management Suite)	Dell centralized management tool for ThinOS devices.
APT (Admin Policy Tool)	A local configuration tool for ThinOS devices.
