A program header is a crucial part of an executable file that provides the operating system with the necessary information to load and execute a program. It contains metadata about the program's segments, including their sizes, locations, and permissions, ensuring the program is correctly mapped into memory during execution.

Program Header

An executable file is a type of computer file that contains a program capable of being executed or run as a process on a computer. These files are typically compiled from source code and can vary in format depending on the operating system, such as .exe for Windows or ELF for Linux.

Executable File

An operating system (OS) is the fundamental software that manages computer hardware and software resources, providing common services for computer programs. It acts as an intermediary between users and the computer hardware, ensuring efficient execution of applications and user tasks.
