• Memory is the most important component of a computer system since it allows it to accomplish simple tasks. There are two types of computer memory: primary memory (RAM and ROM) and secondary memory (hard drive, CD, etc).
• Read-Only Memory (ROM) is primary-non-volatile memory, while Random Access Memory (RAM) is primary-volatile memory.
• RAM is also referred to as read-write memory, main memory, or primary memory.
• This memory stores the programmes and data that the CPU required throughout the execution of a programme.
• Memory that can only be read (ROM) Stores critical information needed to run the system, such as the application required to start the machine. It isn't flammable. Its data is always saved. Used in embedded systems or in situations where the programming does not need to be changed.
