Microsoft Windows Vista’s new feature is the sleep function. This function has the benefits of earlier Windows’ hibernation & standby modes. By sleep function you can easily resume you PC faster than in the state of hibernation or standby.
Before going to the sleep function details, let me quickly explain you how standby and hibernation works. Standby mode saves everything to RAM and you can resume your session from RAM as long as you have power to the motherboard. Hibernation works the same way except that it saves directly to hard disk and you can resume even after power loss. Among these, standby function is faster because it utilizes the speedy data transfer rate of RAM.
Now comes the sleep feature. Which acts as both hibernation and standby in single button. You can send your pc to sleep by pressing the power button in start menu. When you do this, your entire working session including all open documents are saved to both RAM & hard drive. When you start the PC next time, these data will be available for quick access.
The advantage of this function over standby is that, it is saved on to Hard drive as well as RAM. Thus even if you loss power, you can easily access data from hard disk.
In short, sleep function works as standby when there is still power and works as hibernation when there is power loss. I believe by combining both hibernation and standby function, MS have done a great job with Windows Vista.
