How is an executable file different from a data file?
a. Unlike a data file, executable files can be used for a presentation.
b. Unlike a data file, executable files contain numbers, words and pictures.
c. Unlike a data file, you cannot open and read executable files.
d. Unlike a data file, you can manipulate an executable file.
The correct answer and explanation is :
Correct Answer: c. Unlike a data file, you cannot open and read executable files.
Explanation:
Executable files and data files are two fundamentally different types of computer files, each serving distinct purposes in the operation and use of software.
An executable file contains a program or a set of instructions written in a machine-readable format. These files are meant to be executed—or “run”—by the computer. Examples include .exe files on Windows, .app on macOS, or .sh on Linux. When you double-click an executable file, it launches a program, such as a word processor, web browser, or game. These files are compiled from source code and are not meant to be opened or edited by users directly. If you try to open an executable file in a text editor, you’ll likely see a string of unreadable characters, because the contents are in binary form—designed to be interpreted by the computer, not humans.
In contrast, a data file stores information that can be created, read, and modified by programs or users. Examples of data files include .txt, .docx, .xlsx, and .jpg. These files may contain text, numbers, images, or other types of user data. A word processing file, for instance, holds the content of a document that a user can edit. Data files are usually readable and understandable when opened in the appropriate program.
Therefore, option C is correct: “Unlike a data file, you cannot open and read executable files.” This emphasizes the core distinction—while data files are meant for human interaction and often contain readable content, executable files are meant for the computer to run, not for the user to interpret directly.
Understanding the difference helps users avoid accidentally modifying critical program files and also protects them from running potentially harmful executable files unknowingly.
