RAM and ROM
- What does RAM stand for? random access memory
- Data is loaded into RAM from long-term storage (ie- the hard-disk drive) for execution/processing by the CPU.
Having too little RAM can lead to performance problems as data is paged back to the hard drive in order to make
space for data that is being loaded into RAM.

- What does ROM stand for? Read only memory
- a general term of any storage medium that can only be read from, not written to (under normal
circumstances).

- What does the term volatile memory mean?
- Volatile memory contrary to non-volatile memory, is computer memory that requires power to maintain the
stored information; it retains its contents while powered, but when power is interrupted stored data is
immediately lost. Volatile memory has several uses, for example as a RAM drive. In addition to usually being
faster than forms of mass storage such as a hard drive, volatility can protect sensitive information, which
becomes unavailable on power-down, and is vulnerable to malicious access only while powered.
