Primary memory is computer memory that is accessed directly by the CPU. This includes several types of memory, such as the processor cache and system ROM. However, in most cases, primary memory refers to system RAM. RAM is volatile memory, meaning it is erased when the power is turned off.
Keeping this in consideration, which type of memory is ROM?
Data in RAM is not permanently written. When you power off your computer the data stored in RAM is deleted. ROM is a type of non- volatile memory. Data in ROM is permanently written and is not erased when you power off your computer.
Is ROM a primary or secondary storage device?
Examples of Primary Storage. ROM: Unlike RAM, Read Only Memory (ROM) is both a non-volatile and permanent form of primary storage. ROM retains its contents even if the device loses power. Similar to a blank CD or DVD, PROM does not comes with data stored on the chip.
Is a cache primary or secondary?
In this case, primary storage typically refers to random access memory (RAM), while secondary storage refers to the computer's internal hard drive. RAM, commonly called "memory," is considered primary storage, since it stores data that is directly accessible by the computer's CPU.
