What will I learn?

The Coding Decoding Computer Course provides a quick, hands-on understanding of text encoding, UTF-8, and basic checksum error detection. You'll learn how characters are mapped to bytes, how to examine hex data, how to construct and verify frames, and how to mimic faulty transmissions. Using straightforward examples in common programming languages, you'll create simple integrity checks, grasp their limitations, and understand when to opt for more robust approaches like CRCs or cryptographic hashes.

Elevify advantages

Develop skills

  • Implement text encodings: convert characters, code points, and UTF-8 bytes.
  • Compute checksums quickly: XOR, sum modulo 256, and detect errors manually.
  • Build and validate frames: [DATA]+[CHECKSUM], detect and log corrupt packets.
  • Write compact receiver logic: parse frames, recompute checksums, handle errors.
  • Choose integrity methods wisely: checksum vs CRC vs HMAC for internal protocols.

What our students say

Your lessons are perfect. I purchased the one-year package and finally have the opportunity to follow various topics of my interest without needing to change platforms... I thank you for everything you do, I've already recommended you to other people...

I like how the lessons are straight to the point and how I can change chapters and skip content I don't need.
