Which of the following is NOT a component of a GUI-based application?a.Compilerb.TextFieldc.Buttond.ComboBox

1. Break Down the Problem

We need to identify which option listed is not a component typically found in a graphical user interface (GUI) application.

2. Relevant Concepts

A GUI-based application is made up of various components that allow users to interact with the software visually. Common components include:

• TextField: A component for user input.
• Button: A clickable element that performs an action.
• ComboBox: A dropdown element for selection.

3. Analysis and Detail

Now, let's analyze each option:

1. a. Compiler: This is a software tool that translates code from a high-level programming language to machine code. It is not part of the user interface components.
2. b. TextField: A common GUI element for textual input.
3. c. Button: An essential GUI component that users click to perform actions.
4. d. ComboBox: A dropdown interface component for selection.

4. Verify and Summarize

The only option that does not belong to GUI components is the Compiler. The other options (TextField, Button, ComboBox) are all standard components found in GUI applications.

Final Answer

a. Compiler is NOT a component of a GUI-based application.
