Android is a Java virtual machine. The operating system is Linux (called "the kernel" in cellphone-speak). The history log is something used - by system developers - for debugging problems, it's not going to mean anything to you. You'll just drive yourself crazy trying to figure out what all those entries, that will be pretty cryptic to you, mean.
What it means in this case is that some hardware (you'd need logcat to have been running at the time to find out what) interacted with the firmware. Since that's happening constantly, there's no way to determine, from the history log, what it was.
