Explanation

A loader is a system program that loads executable programs from secondary storage into main memory and prepares them for execution. It allocates memory, relocates addresses, and initializes the program. Assemblers convert assembly code to machine code, linkers combine object files, and compilers translate high-level code to machine code.
