Are your students struggling to understand how computers store and process data across text, images, audio, and video?

Help students strengthen computer science reading comprehension and build stronger explanations using evidence with these data encoding reading worksheets!

This print-and-go resource makes it easy to add technology literacy to your AP Computer Science or digital systems unit-no prep needed.

This resource focuses on helping students understand how different types of data are encoded, stored, and processed in computer systems.

Through carefully designed reading passages and targeted comprehension questions, students explore key topics such as ASCII and Unicode, image formats like JPEG and PNG, audio and video formats, compression methods, and metadata.

The included questions require students to analyze information, apply concepts, and justify answers using evidence from the text, making this an excellent fit for rigorous Grade 12 AP-level coursework.

Content is based directly on real concepts such as binary representation, file formats, compression techniques, and multimedia integration .

⭐ What’s Included

✅ 3 Reading Comprehension Worksheets

Each worksheet includes 3 reading passages and 25 questions.

In total, 3 worksheets include 9 reading passages and 75 questions covering topics like text encoding (ASCII, Unicode), image formats (JPEG, PNG, GIF), audio/video formats (MP3, WAV, MP4), compression (lossy vs lossless), and metadata.

✅ 1 Cloze Passages Worksheet (fill-in-the-blank version for support/differentiation)

Students complete key vocabulary and concepts related to encoding, compression, multimedia, and data processing.
