Understanding Computer Systems: The Fetch-Execute Cycle

What is the primary function of a computer as described in the video?

• To connect people via social media

• To provide entertainment through games

• To process data by taking input and delivering output

• To perform mathematical calculations

What is an example of a complex input and output process in a computer system?

• Playing a video game

• Listening to music

• Typing a document

• Turning on a light switch

What could be an output in a gaming console scenario?

• Vibration feedback

• Keyboard input

• Electricity consumption

• Internet connectivity

What is stored in the memory of a computer?

• Physical components

• Computer programs

• Internet data

• Electricity

Which component inside a desktop computer is primarily responsible for executing instructions?

• Hard drive

• RAM

• Graphics card

• CPU

What is the purpose of the large fan over the processor in a desktop computer?

• To increase processing speed

• To provide light inside the case

• To cool down the processor

• To reduce electricity usage

What happens during the fetch stage of the fetch-execute cycle?

• The CPU stores data in Memory

• The CPU outputs data to the monitor

• The CPU retrieves the next instruction from memory

• The CPU powers down to save energy

What is the role of RAM in the fetch-execute cycle?

• To cool down the system

• To hold instructions temporarily for the CPU

• To supply power to the CPU

• To provide permanent storage

What does the CPU do with an instruction after fetching it from the RAM?

• It ignores the instruction

• It decodes the instruction

• It sends the instruction back to the input device

• It stores the instruction permanently

What does the CPU do after decoding an instruction?

• It deletes the instruction

• It sends the instruction to the printer

• It executes the instruction

• It saves the instruction to the hard drive
