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 record corrupt packets.
- Write efficient receiver logic: parse frames, recalculate checksums, manage errors.
- Select integrity methods appropriately: checksum versus CRC versus HMAC for internal protocols.

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.

Mariana FerresPhotography Student
I like the content and the way videos are presented and transcribed, which speeds up the process!

Luciana AlvarengaNail Design Student
The platform is fast, simple to use. The diversity of content and complementary videos help a lot with learning.
