Can you define DMA, and discuss how it interfaces with devices containing firmware or microcontrollers?

As a firmware engineer, you need to be intimately familiar with the different types of devices and computer systems and how they interact with each other. Much of the code you program into firmware or microcontrollers will work with other parts of the computer system or external devices. Since this is a technical question, make sure to use easy-to-understand language and keep your answer brief and to the point. The Tesla interviewer will ask you additional questions if they need more information or explore the topic in more detail.
