Does the computer hot boot and the cold boot concretely have what difference?

Does the PDA have a "hot boot" and a "cold boot" like a desktop computer?

A: Warm Reset (Hot boot): Usually you can see "reset" on the back of the handheld computer, press the "reset" key once, the handheld computer is running hot boot. After the hot boot, the system will normally require the screen locator to run, be sure to finish the screen locator and then reboot.

Cold Reset (Cool boot): Press the key to open (please refer to the use of the instructions) at the same time, then press the "reset" key, and then put off the "reset" key and then put off the key to the power supply, at this time the screen will appear system information, continuous point voltage power to open the key, the system will run hardware tests, including LED, IrDA, Speaker, mic and so on. Typically this action also provides an operating mode for OS upgrades. Please note that all previously entered data will be lost after the cold boot, so keep the backup data on your computer before running
