Embedded and Real Time Systems MCQ

What is Embedded and Real Time Systems

Embedded and real-time systems are two of the most important technological advancements in recent times. An embedded system is a computer system that is specifically designed to perform a particular task or set of tasks, often with limited resources such as processing power or memory.

These systems are typically found in everyday devices such as microwaves, washing machines, and even cars.

On the other hand, real-time systems refer to computer systems where response time is critical to the success of the application. These are essentially systems that must produce results within a certain time frame or risk failure. Examples include flight control systems and medical monitoring equipment.

Both embedded and real-time systems have become increasingly important in our lives as we continue to rely on technology more heavily each day. From smartphones to self-driving cars, these technologies have revolutionized how we live and work.
