What is the difference between Hardware and Software? Give examples of Hardware and Software to support your answer.

​Hardware and Software

​Hardware is something that we can physically touch. A keyboard and mouse are things that we can touch. A monitor and the computer itself are other good examples of hardware.

​Hardware

• ​Monitor

• ​Keyboard

​A laptop computer has a ‘Battery low’ indicator that starts flashing red when the battery power falls below 20%, but only if the laptop is not charging.

Battery below 20%​	Charging	Battery low flashing red
​True	​True	​False
​False	​False	​False
​	​	​
​	​	​

​Remember to use the Logic Operators to work this out. Example: The Battery is below 20% AND the battery is Charging. This would make the Battery low flashing red True.

​Using the other logic operators.

​The battery is NOT below 20% AND the battery is NOT charging. This means the battery low flashing red would be FALSE.

​

The battery ​is below 20% AND the battery is NOT charging. This means the battery low flashing red would be TRUE

​What is AI?

What doe AI stand for?​

Open Ended

What does the word artificial intelligence mean to you? Give examples of where you have seen the use of AI.

​Artificial Intelligence is not about making machines that are smarter than humans.

​

Machines have to learn from instructions that are given to them to perform different tasks.​

​

Machines will learn by being programmed.​

​

A machine can only perform a task as good as the example it has been given​ in the first place.

​They don't think for themselves.
