Exploring Water Computers

What is used to create logic gates in the water computer?

• Transistors

• Dominoes

• Electricity

• Water flow

Answer explanation

Water flow is used to create logic gates in the water computer, not transistors, dominoes, or electricity.

What does an AND gate do?

• Activates if only one input is activated

• Activates if either of the inputs is activated

• Activates if both inputs are deactivated

• Activates if both inputs are activated

Answer explanation

An AND gate activates only if both inputs are activated, making the correct answer choice 'Activates if both inputs are activated'.

What represents a '1' in a water computer?

• A full bucket

• A dry bucket

• A leaking bucket

• A certain volume of water

Answer explanation

A '1' in a water computer represents a certain volume of water, not a full bucket, dry bucket, or leaking bucket.

What problem did the creator encounter with water adhesion?

• The water was too clear

• The water was too cold

• The water was too hot

• The water was too sticky

Answer explanation

The creator encountered a problem with water adhesion because the water was too sticky, which hindered the desired outcome.

What is the purpose of drilling a small hole in the siphon of the greedy cup?

• To prevent water from leaking

• To create a slow leak

• To make it look nice

• To stop the flow of water

Answer explanation

Drilling a small hole in the siphon of the greedy cup creates a slow leak, allowing water to flow out gradually instead of all at once.

What does the exclusive or (XOR) operation do?

• Produces a 1 if both inputs are 0

• Produces a 1 if only one input is 1

• Produces a 1 if both inputs are 1

• Produces a 0 if both inputs are different

Answer explanation

XOR operation produces a 1 if only one input is 1, making it the correct choice in this scenario.

What is necessary to add two binary numbers together?

• A full adder

• A half-eater

• A double siphon

• A simple bucket

Answer explanation

To add two binary numbers together, a full adder is necessary as it can handle the addition of multiple bits and carry over operations.

What does the water computer use to represent bits?

• Color of the water

• Volume of the water

• Temperature of the water

• Speed of the water flow

Answer explanation

The water computer uses the speed of the water flow to represent bits, not the color, volume, or temperature of the water.

How is data stored in a water computer?

• Using buckets of different sizes

• Through the variation of water pressure

• By changing the color of the water

• In the form of water levels

Answer explanation

Data is stored in a water computer in the form of water levels, representing different values or states within the system.

What mechanism is used to reset the water computer?

• Drain all the water

• Add ice to cool the system

• Increase the water flow speed

• Shake the buckets

Answer explanation

To reset the water computer, the mechanism used is to drain all the water. This action helps to restart the system and clear any existing data or settings.
