2.4. Boolean Logic

What do binary digits (0s and 1s) in a computer system represent?

• The amount of data that can be stored

• The flow of electricity through wires and switches

• The speed of the processor

• The size of the memory chips

Why are computers considered electrical devices?

• Because they require a battery to operate

• Because they can only be used when plugged into an outlet

• Because they process information by controlling the flow of electricity

• Because they emit electrical waves

What is the role of transistors in a computer system?

• They increase the speed of data processing

• They store large amounts of data

• They control the flow of electricity and process information

• They convert binary data into human-readable form

How is the flow of electricity represented in binary when it goes through a cable or switch?

• As a 1 when there is no electricity and as a 0 when there is electricity

• As a 0 when there is no electricity and as a 1 when there is electricity

• As a 2 when there is a strong current and as a 1 when there is a weak current

• As a 1 for both cases, regardless of the flow of electricity

Transistors are electrical components made from which type of materials?

• Insulator materials

• Conductor materials

• Semiconductor materials

• Composite materials

What is the function of transistors in electrical circuits?

• To store electrical energy

• To act as electrically-controlled switches

• To increase the voltage of a circuit

• To provide insulation between different circuit parts

What analogy is commonly used to describe the function of a transistor?

• A bridge

• A tap

• A door

• A battery

In a transistor, what happens when the "base" input is turned on?

• The current is stopped completely.

• The current bypasses the collector and emitter.

• A small current allows a larger current to flow from the collector to the emitter.

• The transistor overheats and shuts down.

What are transistors in a CPU configured into to perform operations?

• Algorithms

• Circuits

• Programs

• Systems

What is an example of a circuit that transistors can form?

• Multiplier

• Adder

• Divider

• Subtractor
