A compiler, interpreter, and assembler are different types of software tools used in the process of programming.
A compiler is a program that translates the entire source code written in a high-level programming language into machine code or bytecode all at once. The resulting compiled code can then be executed directly by the computer's hardware. Compilers optimize the code for efficiency, producing faster-running programs.
An interpreter executes the source code line by line, translating and executing each instruction as it encounters them. The interpreter does not produce a standalone executable file but directly runs the program. Interpreters are often used in scripting languages and allow for dynamic code execution, making them more flexible for tasks like debugging and prototyping.
An assembler, specifically used in low-level programming, translates assembly language code into machine code. Assembly language is a human-readable representation of machine code, using mnemonic instructions and symbols instead of binary digits. Assemblers perform a one-to-one mapping between assembly instructions and machine instructions, enabling direct interaction with the computer's hardware.
