codes

In general knowledge, "codes" refer to systematic sets of symbols, rules, or instructions used to convey information. They can be found in various contexts, such as programming (where instructions are given to computers), communication (like Morse code for messages), or encryption (to secure sensitive information). Codes help organize and simplify complex ideas, making them easier to understand or transmit. Each code requires a specific key or understanding to decode the information, ensuring that only those familiar with it can interpret its meaning accurately.
