What is an Executable File? | Computer Fundamentals for Cyber Security
What is an executable file and what happens when you run a program?
An executable file is not just data — it contains machine instructions that the CPU can execute.
In this video, we explain:
• What an executable file is
• What is inside an executable
• Code, data, and metadata sections
• Difference between .exe and ELF
• How programs are loaded into memory
Understanding executables is essential for reverse engineering, malware analysis, and cybersecurity.
