BIOS is a program (stored in ROM), not a memory.
However the BIOS uses a battery backed up RAM to store a variety of settings and parameters. This BIOS RAM is itself volatile (it can only store data when powered), however the battery backup provides power to this RAM when the main power of the computer is off (making it act as if it were nonvolatile). When this battery dies the BIOS RAM will lose its data and (after the battery is replaced) the machine may have to be reconfigured from scratch before the machine will startup correctly.

8 What is the difference in volatile and nonvolatile memory?
1. What is the difference in volatile and nonvolatile memory?
Is EEPROM a volatile or nonvolatile memory?
Non-volatile. It retains its memory even if power is removed.
The system BIOS is stored on nonvolatile memory called what?
Bios rom
Is volatile memory or nonvolatile memory faster?
Volatile memory is temporary. Non-volatile is used for storing information after the the computer is shut down.
One computer has either volatile or nonvolatile storage but never both?
Modern Computers have both volatile memory - RAM and non-volatile memory - Hard Disk
When a computer is turned off does volatile memory lose its contents?
yes, and nonvolatile does not
What can nonvolatile memory do?
Non-volatile memory can retain its contents through a loss of power, assuming the shutdown was properly performed.

Is the nonvolatile memory where the diagnostic software the bootup instructions and a limited IOS are stored?
These form part of the BIOS software which is stored either on a non-volatile ROM chip on the motherboard, or in more modern computers, on a flash memory chip so that new information can be updated as required.
Is eeprom a volatile or nonvolatile?
Nonvolatile, it stores its data with or without power.
Is glucose volatile or nonvolatile?
Yes
Is volatile memory permanent?
A flash memory chip is a close relative to EEPROM, it differs in that it can erase one block or page at a time. Therefore flash memory is a non volatile memory.
