How is an executable file different from a data file?

• A. Unlike a data file, you cannot open and read executable files
• B. They are the same in all respects
• C. Executable files take up more space
• D. Data files can execute programs

Answer: (A)

Executable files contain machine instructions that the computer’s processor can run, while data files store information for programs to read, display, or process. The operating system loads an executable into memory and starts its execution, whereas a data file is not meant to be executed; it’s meant to be interpreted or displayed by software. That’s why the best choice says you cannot read an executable file in the same way you can read a data file. When you open a binary executable in a normal text viewer, you usually see garbled characters and nonhuman content because it’s not written as readable text. Data files, like documents or images, contain information that is human- or program-readable, making their contents meaningful when opened with the appropriate application. Other options don’t fit because executables aren’t inherently larger or smaller than data files by necessity, and data files are not capable of executing programs.
