Embedded systems are common in devices such as cars, medical equipment, routers, and smart appliances. Interviewers ask this to assess whether you understand how software interacts with hardware under tight resource and timing constraints.
Explain the basics of embedded systems.
Your answer should cover:
A strong answer should define the concept clearly, describe the typical architecture at a high level, and mention where embedded systems are used in practice. You do not need deep electrical engineering detail, but you should show that you understand the interaction between hardware, low-level software, and timing-sensitive behavior.
