What will I learn?
The Coding Decoding Computer Course provides a quick, practical understanding of text encoding, UTF-8, and basic checksum error detection. You'll learn how characters map to bytes, examine hex data, construct and verify frames, and simulate faulty transmissions. Using straightforward examples in common programming languages, you'll create simple integrity checks, grasp their limitations, and decide 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], identify and record corrupt packets.
- Write efficient receiver logic: parse frames, recalculate checksums, manage errors.
- Select integrity methods appropriately: 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 a range of topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...
