Defferentiate Ram and Rom

Expert Solution
Step 1: Explanation

RAM is volatile memory, which means that when you restart or shut down your computer, the information temporarily held in the module is deleted. Because the data is stored electrically on transistors, it vanishes when there is no electric current. When you request a file or piece of information, it is either fetched from the computer's hard drive or from the internet. Because the information is saved in RAM, it is instantaneously available when you transition from one program or page to another. The memory is wiped when the machine is turned off until the process is restarted. Users can quickly update, upgrade, or extend volatile memory.

ROM is Non-volatile memory refers to information is permanently stored on a chip. The memory does not rely on an electric current to save data; instead, binary code is used to write data to individual cells. Non-volatile memory is used for elements of the computer that do not change, such as the software's initial boot-up phase or the firmware instructions that allow your printer to function. The ROM is unaffected by turning off the machine. Users are unable to alter non-volatile memory.
