Question - What does it mean to "power cycle" a device ?
Answer -
1:-
Power cycling an electronic device is a technical way of saying "resetting" it. When you power cycle a device, you turn it off and then turn it back on again. Pretty high-tech, huh? Usually, you should let the device sit for a couple seconds after turning it off to make sure the memory in the device is fully cleared before turning it back on.
Any electronic device can be power cycled, but the term is frequently used with cable modems, DSL modems, and routers. This is because small internal errors in these devices can prevent them from functioning correctly. Resetting them typically fixes the errors and allows them to work correctly again.

If the drive only says "CD-ROM" or "DVD-ROM" then it probably does not burn CDs or DVDs. If it says CD-R, then it can burn recordable CDs and if it says CD-RW, it can write and rewrite to rewritable CDs.
If the drive says DVD-R or DVD+R, it can burn DVD-R or DVD+R discs. If it says DVD-RW or DVD+RW, then it can burn rewritable DVDs.
Drives that can burn CDs and read DVDs are often referred to as "Combo Drives" by many PC manufacturers. Apple Computer uses the term "SuperDrive" to refer to drives that can read and write to both CDs and DVDs.
