Boot volume
The formula for calculating tank pressure in a compressed air system is: Pressure (P) (Volume of Air in Tank (V) Temperature (T) Gas Constant (R)) / Volume of Tank (V)
Basically the system volume is required to start up, and the boot volume contains the OS. From http://support.microsoft.com/kb/314470: The system volume refers to the disk volume that contains the hardware-specific files that are needed to start Windows, such as Ntldr, Boot.ini, and Ntdetect.com. On computers that are running the Intel x86 line of CPU processors and later versions, the system volume must be a primary volume that is marked as active. This requirement can be fulfilled on any drive on the computer that the system BIOS searches when the operating system starts. The system volume can be the same volume as the boot volume. However, this configuration is not required. The boot volume refers to the disk volume that contains the Windows operating system files and the supporting files. By default, the Windows operating system files are in the WINDOWS folder, and the supporting files are in the WINDOWS\System32 folder. The boot volume can be the same volume as the system volume. However, this configuration is not required. There is only one system volume. However, there is one boot volume for each operating system in a multiboot system."
Nothing special. But depending on the compression techniques used, it's a wasted effort, since it won't save more space having a compressed file on a compressed file system.

Normal atmosphere contains moisture in varying percentages, ie humidity. When a given volume of air is compressed, the moisture is "compressed" with it. The dryer removes the wetness so that the air pressure is constant and contamination free.
A gas is a state of matter that can be compressed and can flow. Gases have no definite shape or volume, allowing them to take the shape of their container and flow easily. They can be compressed to reduce their volume.
