TED-Ed: How exactly does binary code work? - Jose Americo N L F Freitas

The video explains how binary code is fundamental to computing, storing data as sequences of 1s and 0s. It covers how binary encodes numbers and text, and its application in multimedia like video and audio. The video also discusses data compression techniques and explores future computing technologies like ternary and quantum computers, highlighting binary's current dominance due to its stability.

Why do computers use binary code to store data?

• Because it is the only language computers understand

• Because it can store more data than any other system

• Because it is a reliable way of storing data

• Because it is the most complex language

How is the number 84 represented in binary?

• As a single binary digit

• As a sequence of eight binary digits

• As a sequence of binary digits based on powers of 2

• As a sequence of binary digits based on powers of 10

What technique is used to digitize sound waves into binary?

• Waveform encoding

• Amplitude modulation

• Pulse code modulation

• Frequency modulation

What is run-length encoding used for?

• To compress binary data by encoding repeated values

• To encrypt binary data

• To increase the size of binary data

• To convert binary data into text

What is a potential alternative to binary computing?

• Digital computing

• Ternary computing

• Classical computing

• Analog computing
