Random Access Memory, a type of computer memory that is volatile and temporary, used to store data that can be accessed quickly by the CPU.	In cache memory, a miss occurs when the requested data is not found in the cache and needs to be fetched from the main memory.
A technique that uses a portion of the computer's hard drive as an extension of RAM, allowing the system to run more programs simultaneously.	A small circuit board that contains multiple RAM chips and is inserted into a computer's motherboard to provide additional memory.
A type of computer memory that retains data even when power is not supplied, such as ROM or flash memory.	The delay between the time a memory request is made and the time the data is accessed, measured in nanoseconds.

Software that is stored in Read Only Memory and is essential for the operation of hardware devices.	A type of non-writeable computer memory that retains its contents even when the power is turned off.
A type of ROM that allows for the erasure and reprogramming of its contents,	The process by which a device retrieves instructions from ROM to start up and initialize its hardware components.
Software used to flash ROMs, kernels, and other system files onto Android devices.	A program stored on the device that determines which software to load when the device is powered on.
