Computer code refers to the instructions that a computer can understand and execute. Source code is human-readable code written by programmers using a high-level programming language (e.g., Python, Java, C++).Object code is the output of a compiler after translating source code into machine-readable instructions, but it's not yet executable on its own and often needs to be linked with other object files. Machine code is the lowest-level programming language, directly executable by a computer's CPU. It consists of binary instructions (0s and 1s).Bytecode is an intermediate form of code that is typically executed by a virtual machine (like the Java Virtual Machine). It's platform-independent.
