Essential Question

How does a computer take letters, images, sound, and video — and convert them into numbers it can store and process?

🎯 Learning Intention

I will explain how computers encode characters and measure digital information using bytes and file sizes.

I can explain character encoding (ASCII, Unicode, UTF-8).
I can compare file sizes using KB, MB, GB, and TB.
I understand why different media formats take different amounts of storage space.

Purpose: How text becomes numerical data.

Purpose: How those numbers become stored files of different sizes.

Together, they answer:

“How does information become data, and how does data become files?”
