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 will 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 will 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.
