What will I learn?
The Coding and Decoding Computer Course provides a quick, practical understanding of text encoding, UTF-8, and basic checksum error detection. You'll learn how characters are mapped to bytes, how to inspect hexadecimal data, how to construct and verify frames, and how to simulate 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 corrupted packets.
- Write compact receiver logic: parse frames, recompute checksums, handle errors.
- Choose integrity methods wisely: checksum vs CRC vs HMAC for internal protocols.

Your classes are perfect. I got the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...
