Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

when i eject usb it goes but still live with power
As I understand it, "Eject" and "Safely remove drive" both unmount the attached USB drive/memory stick from your file system so physically removing the device won't cause any file system corruption. There's no hardware on the motherboard which will "switch off" the power to the USB ports.
I have a sandisk usb with a light in it... when I eject it on my desktop running Squeeze, the light remains on. On my laptop running Jessie, when I eject or "safely remove" the light goes out and remains out. I'd say that "it depends". If it's a big deal I suppose I could boot my desktop on Jessie from USB and test whether it's the mobo or the release, but either way the answer is likely "maybe, maybe not".
On my desktop, the USB ports are always live so long as the computer is connected to the mains and that socket is live - even if the computer is switched off. I use USB for backups every day and just unmounting is OK.
The "eject" is to ensure files are closed and the file system is unmounted. Has nothing to do with power.
Correct also that the motherboard will still provide power to any USB accessory while it is physically plugged in, and the motherboard is powered on and operating. Excepting probably deep sleep/hibernate. Meanwhile there are also wake from hibernate via USB signalling cases.
