## What do you learn in Coding Theory

Coding Theory explores how to efficiently and reliably transmit information through noisy channels. You'll dive into error-correcting codes, data compression, and cryptography. The course covers linear codes, cyclic codes, Reed-Solomon codes, and their applications in digital communication. You'll also learn about information theory, entropy, and channel capacity.

## Is Coding Theory hard?

Coding Theory can be challenging, especially if you're not comfortable with abstract math. It involves a mix of algebra, probability, and some computer science concepts. The math can get pretty intense, and wrapping your head around the theoretical aspects takes time. But if you're into puzzles and problem-solving, you might find it really engaging.
