Coding theory was invented in the forties to protect data transmitted through a noisy communication channel. Important families of codes have been adopted in major standards in communications, such as convolutional code (GSM), Turbo code (3G, 4G), LDPC code (Wifi), and Polar code (5G). Apart from communications, the theory has also found its vast success in numerous important areas in the fields of computer science and electrical engineerings such as data storage, memory and cache, cryptography, private information retrieval, and distributed computing.

Network Coding
Network coding serves as a technique aimed at enhancing both the data transmission rate and security against eavesdropping within a network. Instead of solely forwarding packets, intermediate nodes merge them, typically employing linear combinations as vectors. Coding theory finds application in network coding in diverse manners. For instance, it aids in bolstering system reliability amidst network errors or data loss. Furthermore, it facilitates the formulation of functions for packet combination at nodes, ensuring successful packet reconstruction at destination nodes.
