1. In earlier computers the most common form of random-access storage for computer main memory employed an array of doughnut-shaped ferromagnetic loops referred to as __________.
2. RAM, ROM, PROM, EPROM, EEPROM, and flash memory are all examples of __________ memory types.
3. A _________ RAM is made with cells that store data as charge on capacitors.
4. A __________ RAM is a digital device that uses the same logic elements used in the processor.
5. Three common forms of read-mostly memory are: EPROM, EEPROM, and _________.
6. A __________ failure is a permanent physical defect so that the memory cell or cells affected cannot reliably store data but become stuck at 0 or 1 or switch erratically between 0 and 1.
