RTOS stands for Real-Time Operating System. It is designed to handle time-sensitive tasks and has a deterministic response time.

• RTOS is used in applications where timing is critical, such as aerospace and automotive industries.

• RTOS has a predictable response time, whereas normal OS may have varying response times.

• RTOS is designed to handle tasks with strict deadlines and priorities.

• RTOS typically has a smaller footprint and lower overhead than normal OS.

• Examples of RTOS inclu...read more

Embedded systems are computer systems designed to perform specific tasks within a larger system.

• Embedded systems are often found in everyday devices such as cars, appliances, and medical equipment.

• They are designed to be low-power and have limited resources.

• They are programmed to perform specific tasks and are not meant to be general-purpose computers.

• They often have real-time constraints and must respond quickly to external events.

• They can be programmed in a variety of langu...read more

OOPS concepts are the fundamental principles of Object-Oriented Programming.

• Encapsulation - binding data and functions together

• Inheritance - creating new classes from existing ones

• Polymorphism - ability to take multiple forms

• Abstraction - hiding implementation details

• Class - blueprint for creating objects

• Object - instance of a class

• Method - behavior of an object

• Constructor - method used to initialize an object

• Destructor - method used to destroy an object
