Study Notes

Embedded Systems

Designed for specific tasks on optimized hardware.
Users are responsible for system support.

Linux Origins

Originally developed for Intel 386 PCs.

Linux Distributions

Bundling utilities, management tools, and applications with a Linux kernel forms a distribution.

Software Release Cycle

Describes frequency of software upgrades.

OS X Characteristics

Fully certified UNIX distribution.
