Android ROM?

[LifeIsLaughter]

I've heard the term ROM being used a lot, the primary use being "rooting" it. What exactly is ROM, what do people mean when they say to root it, and how is it done?

Might sound like a stupid question, but gotta start somewhere right?

"Read Only Memory".

In this case it probably refers to the storage holding the device firmware, or more colloquially, the firmware itself.

Root is an account on a unix system with very high privileges on the machine, like administrator on Windows.
