Random Access Memory (RAM): High-speed memory which holds a copy of the operating system, any currently executing applications, and any information undergoing processing. Ram is volatile, which means all information in the memory is lost when the computer is turned off (unless resume mode is on).
Read Only Memory (ROM): A type of memory, which the computer can access, but cannot change. ROM is non-volatile memory, which means that the information stored in ROM is permanent-it is not lost when you turn the computer off.
Reboot: See Restart
