• Lack of skilled developers, high development costs, compatibility issues with different hardware platforms

• Limited resources, real-time constraints, hardware and software integration, power management, security, and testing.

• Lack of industry standards, limited support for third-party libraries, difficulty in software updates

What is the difference between a microcontroller and a microprocessor in an embedded system?

• A microcontroller is more powerful than a microprocessor in terms of processing speed.

• A microcontroller is a single integrated circuit that contains a processor core, memory, and peripherals, all on a single chip, while a microprocessor is a general-purpose CPU that requires external memory and peripherals.

• A microcontroller is used in desktop computers, while a microprocessor is used in embedded systems.

• A microcontroller and a microprocessor are the same thing in an embedded system.

What is the role of sensors in an embedded system?

• The role of sensors in an embedded system is to control the system's power supply.

• The role of sensors in an embedded system is to communicate with other devices.

• The role of sensors in an embedded system is to provide physical support to the system.

• The role of sensors in an embedded system is to collect data from the environment or the system itself.

What is the importance of power management in embedded systems?

• Power management is not important in embedded systems.

• Power management is important in embedded systems to optimize energy usage, prolong battery life, and reduce power consumption.

• Power management only affects the performance of embedded systems.

• Power management is only necessary for large-scale embedded systems.
