ELF (Executable and Linkable Format)

ELF, or Executable and Linkable Format, is a standard file format used by many operating systems, like Linux, for programs and libraries. It organizes code, data, and information needed for the system to load and run software efficiently. ELF files contain sections for instructions, variables, and metadata, enabling the operating system to understand how to execute the program and connect it with other code. Think of it as a well-structured blueprint that guides the computer in starting and managing software reliably and securely.
