The video explains the concept of binary code, its purpose, and how it differs from the decimal system used by humans. It highlights that humans use the decimal system due to having ten fingers, while computers, being electronic devices, use binary code. Binary code represents data using switches that are either on or off, corresponding to the digits 1 and 0. This system allows computers to perform calculations and represent various types of data, including numbers, letters, and entire programs.

Why do humans typically use a decimal system for counting?

• Because it is the oldest system

• Because computers use it

• Because we have ten fingers

• Because it is the simplest system

What is a key characteristic of computers that influences their counting system?

• They have a limited memory

• They are electronic devices

• They can only perform simple calculations

• They have a fast processing speed

How can the state of a computer switch be described?

• High or low

• On or off

• Open or closed

• Positive or negative

What do the binary digits 0 and 1 represent in a computer circuit?

• High and low voltages

• On and off states

• Open and closed circuits

• Positive and negative charges

What can binary code represent in a computer system?

• Only numbers

• Only instructions

• Numbers, letters, symbols, and programs

• Only letters
