Document Summary

A set of programs that coordinate all the activities among computer or mobile device hardware. Acts as an intermediary between the two. The kernel is the central component of an os and manages memory, order of processes are executed, and how information is received and sent to devices. Sleep mode: saves any open documents and programs to ram, turns of all unneeded functions, and then places the computer in a low-power state. Can wake up quickly and start where you left off. Hibernate: saves any open documents and programs to a hard disk before removing power from the computer.
