   • Code refers to the instructions written in programming languages like Python, Java, or C++ that computers can execute. It is the foundation for creating software, websites, and applications.
   • Types of code include source code (written by programmers) and object code (processed by a compiler for execution).
   • Coding involves translating human ideas into machine-readable instructions using programming languages.
3. Other Uses:
   • Codes can also be identifiers, such as product codes, area codes, or activation codes for software.
   • In legal contexts, a code may refer to systematically arranged laws, such as a penal code or tax code.
