ROM is checked. CMOS is checked. Virtual Memory is checked. Use the following information for a correct and complete solution. ROM instructions are permanent, which means they are accessible to allow the computer to boot up, unlike RAM, which is empty when the computer is just turned on.
Capacitors hold the electronic signals for the data.
The contents of RAM can change by changing the charge of the capacitors. CMOS memory holds data, but that requires very little power to retain its contents. CMOS holds data as long as it is supplied with battery power. It is, in effect, a compromise between RAM and ROM technology in terms of holding data. A Fill in the best answer 28.
