Binary Revision

What is the primary reason computers use binary code?

• It is a reliable way of storing data.

• It allows for faster processing speeds.

• It is the simplest form of communication.

• It is the only language computers understand.

How do transistors in a computer's memory function?

• They process audio signals.

• They store data in decimal form.

• They convert binary to text.

• They switch between high and low voltage levels.

In binary number notation, what is each position based on?

• 5 raised to some power

• 2 raised to some power

• 8 raised to some power

• 10 raised to some power

What does the binary sequence 01010100 represent in UTF-8?

• The letter A

• The letter T

• The number 84

• The number 100

Why is context important when interpreting binary sequences?

• It reduces the size of binary code.

• It helps determine the language being used.

• It allows for faster data processing.

• It helps distinguish between numbers and text.

How are colors represented in binary for digital images?

• By a single binary sequence

• By three binary sequences for primary colors

• By a hexadecimal code

• By a decimal number

What technique is used to digitize sound waves into binary?

• Waveform encoding

• Frequency modulation

• Amplitude modulation

• Pulse code modulation

What is run-length encoding used for?

• Compressing images by recording repeated pixels

• Encoding text in binary

• Reducing the size of binary code

• Compressing audio files

What is a potential alternative to binary computing?

• Hexadecimal computing

• Ternary computing

• Decimal computing

• Octal computing

Why are binary systems still preferred over ternary and quantum computers?

• They provide more physical stability for data storage.

• They are more cost-effective.

• They are faster.

• They are easier to program.
