Just Enough Operating System (JeOS)

Definition - What does Just Enough Operating System (JeOS) mean?

Just Enough Operating System (JeOS) is a tech design concept in which a leaner version of an operating system (OS) replaces the full version to run on a specific device or hardware setup. The term represents a sea change in the way engineers address the necessity of an OS to a given hardware design. It promotes the idea that "less is more," in terms of operating systems that should be installed in a technology product.

Techopedia explains Just Enough Operating System (JeOS)

JeOS designers have to consider a given OS' kernel or core, as well as tools and utilities required to create a custom OS that enables faster operations and less required installation memory. The use of JeOS designs often corresponds to a virtual appliance method, where a virtual machine (VM) image runs on a given platform.

There also is a tendency for open source operating systems to lead the pack, in terms of JeOS development, even though this model is being adopted by other major licensed operating systems.
