RAM (Random Access Memory) and ROM (Read-Only Memory) are both types of memory used in computers and other electronic devices. Simply put, RAM is used as a temporary workspace for data and programs while they are being used, while ROM is used to store permanent data and programs that are needed to start the device and run other necessary software.
In other words, RAM is like a workspace for your computer to store information it is currently using or processing, while ROM is like a permanent storage space to store the device's software and other essential information that is not lost when the device is turned off.
