In microprocessor systems, two primary types of memory are commonly utilized. These are commonly referred to as Read-Only Memory (ROM) and Read/Write Memory, but are more commonly known as ROM and RAM respectively. ROM, as the name suggests, allows for read-only access, meaning that data stored in ROM can only be read and not modified. On the other hand, RAM, or Random Access Memory, permits both the reading and writing of data, enabling the system to store and retrieve information as needed.
