Since it is not possible to un-blow the fuse, so the authenticity of the data remains intact and it is impossible to remove or alter the contents. d. ROM chips are easily swapped between different brands of computers. There are different types of ROM, which include erasable programmable read-only memory, programmable read-only memory, electrically erasable programmable read only memory, and mask ROM. When you power off your computer the data stored in RAM is deleted. 2 - What is solid state storage technology? The times when the information is in the modules is quite short. A random-access memory device allows data items to be read or written in almost the same amount of time, regardless of the physical location of the data within the memory. What is RFID technology? All necessary data is stored in the ROM, which is needed to start your PC and loads operating system. What characteristic of read-only memory (ROM) makes it useful? Data in ROM is permanently written and is not erased when you power off your computer. Not flexible to delete any specific byte, beyond of all data is deleted.
