How computers work? (Computing Systems)

What are the three basic steps a computer performs to process information?

• Input, Calculate, Output
• Input, Store, Retrieve
• Input, Analyze, Display
• Input, Process, Output

What types of data can be considered as input for a computer?

• Letters, numbers, pictures, or instructions
• Only images
• Only numbers
• Only text

Which of the following best describes 'input' in the context of computer operations?

• The final result displayed on the monitor
• Data entered into the computer
• The calculations performed by the CPU
• The storage of data in memory

What role does the CPU play in a computer's operation?

• It stores data permanently
• It performs calculations and processes data
• It connects to the internet
• It displays output on the monitor

How is data typically inputted into a computer?

• Using a scanner
• Using a monitor
• Using a keyboard or a mouse
• Using a printer

Why is the CPU often referred to as the 'brain' of the computer?

• It connects to all peripherals
• It manages the power supply
• It stores all the data
• It performs all the thinking and calculations

What does 'output' refer to in the context of computer functions?

• The storage of data in memory
• The final result displayed after processing
• The calculations performed by the CPU
• The data entered into the computer

Why is it important for computers to receive input before doing any processing?

• Input makes the computer faster

• Without input, the computer wouldn’t have any data to process

• Input helps the computer store more information

• Computers don’t need input to work

In the example of adding numbers, what is the input when calculating 7 plus 9?

• The operation plus
• The result 16
• The numbers 7 and 9
• The CPU's processing

What is the role of input in how a computer works?

• To show pictures

• To tell the computer what to process

• To turn the computer on

• To print information
