How would you store data from a serial receiver line by using a specific data structure?

There are many different processes you can use as a firmware engineer. Some of these will be dependent on the type of system you design, while others may be a personal preference. In either case, when you were asked about specific processes, describe the steps using easy-to-understand, non-technical language. If you do not use the process you are being asked about, provide the interviewer with a reasonable alternative that can be used and is just as efficient.
