Session 8

What is the main function of a computer?

• To convert electrical energy into mechanical energy

• To store, retrieve, and process information

• To only display images

• Only to store information

Which of the following is a basic operation of a computer?

• Drawing pictures

• Flying a drone

• Executing instructions and processing data

• Producing only sound

What does a microcontroller typically contain on a single chip?

• Only sensors

• Processor, memory, and input/output components

• Only memory

• Only a processor

How is a microprocessor different from a microcontroller?

• A microprocessor always includes built-in sensors

• A microprocessor can only be used in cars

• A microprocessor stores mechanical energy

• A microprocessor only has a CPU and requires external components like memory and I/O

Where are microcontrollers commonly used?

• Only in mobile phones

• In satellites only

• In simple devices like washing machines, microwave ovens, and remote controls

• Only in large desktop computers

Where are microprocessors commonly used?

• In large computing devices like laptops and desktops

• In batteries

• In small toys

• In simple circuits without any processing

What role does a microprocessor play in a computer system?

• Controls light emission

• Provides mechanical movement

• Only stores data

• Acts as the brain, performing calculations and processing data

Which of the following best describes the architecture of a microcontroller?

• It consists only of a display

• All necessary components are integrated into one chip

• Components are always separate

• It has no input/output capability

What makes microcontrollers suitable for IoT (Internet of Things) applications?

• They can store massive files

• They consume a lot of power

• They are designed only for gaming

• They are compact and combine processing, memory, and I/O on one chip

Which of these is a key difference between microcontroller and microprocessor applications?

• Both are used only for gaming

• Microcontrollers are used only in spacecraft

• Microprocessors have built-in motors

• Microcontrollers are ideal for dedicated tasks; microprocessors are ideal for general-purpose computing
