Any data stored within, for example, ROM is not lost when the power supply is switched off 4, p33
Permanent; e g PROMs are said to be nonvolatile because they retain their information even after power has been turned off RAM, on the other hand, is volatile (all information is lost when power is removed)
The solid portion of a coating consisting of pigment and binder; it is the portion of the coating left on the surface after it is dry
Storage (hard disk, cd-rom, tape, floppy, etc ) that does not change when the power is turned off, unlike volatile storage that is erased when the power is off
Information that will remain usable by a computer despite loss of power or shutdown
Any substance which does not evaporate or volatilize under normal conditions of temperature and pressure
The memory elements keep their contents when power is removed from the device The element may be one time programmable or "reprogrammable " Examples of the former include fuses and antifuses Examples of the latter include EPROM, and EEPROM storage elements Programmable devices can be both non-volatile and reprogrammable
Any device that retains its stored information after power is removed Examples: EPROMs, flash memory, rotating magnetic discs, optical memory Compare volatile memory
qualifies a memory which retrieves, when it is powered on, the state that it had when it was powered off; EPROM and FLASH memories, floppy and hard disks, and magnetic tapes, are examples of non-volatile memories
That portion of a material which does not evaporate at ordinary temperatures; the solid substances left behind after the volatiles have evaporated
