What will I learn?
This course offers a quick, hands-on understanding of text encoding, UTF-8, and basic checksums for error detection. You will learn character-to-byte mapping, hex data inspection, frame building and validation, plus simulating faulty transmissions. Using examples in common languages, master simple integrity checks, their limitations, and decisions on advanced options like CRC or hashes.
Elevify advantages
Develop skills
- Implement text encoding: convert characters, code points, and UTF-8 bytes.
- Compute checksums quickly: XOR, sum modulo 256, and manual error detection.
- Build and validate data frames: [DATA]+[CHECKSUM], detect corrupt packets.
- Develop compact receiver code: parse frames, verify checksums, manage errors.
- Select right integrity checks: checksum vs CRC vs HMAC for protocols.
