These flashcards cover key concepts related to computer languages, binary systems, character encoding, logic gates, computer architecture, and terminology.

What is the binary system in computing?

The communication that a computer uses, also known as a base-2 numeral system.

What is a Byte?

A group of 8 bits.

How many possible values can a byte represent?

What is character encoding?

The process of assigning binary values to characters so humans can read them.

What is the purpose of logic gates in computing?

They allow transistors to perform complex tasks by controlling electrical signals based on logical conditions.

What does RGB stand for in computing?
