Question 1

Performing an operation on an icon causes a(n)____.

Accepted Answer

Performing an operation on an icon typically generates an event, which is a way for a program to respond to user actions like clicks, keyboard input, or other interactions.

Question 2

With a single CPU,multiple threads execute simultaneously.

Accepted Answer

With a single CPU, threads appear to run simultaneously through time-slicing, where the CPU switches between threads rapidly, but at any instant, only one thread is being executed.

Question 3

Multithreaded programs often run faster and they are more user-friendly.

Accepted Answer

Multithreaded programs can run tasks in parallel, making them faster and more responsive, which contributes to a better user experience.

Question 4

A GUI picture album has a picture or sketch of a screen the user will see when running a program.

Accepted Answer

The answer of A GUI picture album has a picture...

Question 5

A ____ is a rectangular area into which the user can type text.

Accepted Answer

A text box is a GUI element that allows users to input text information into an application or website. It is typically rectangular in shape.

Question 6

In object-oriented languages,the procedural modules that depend on user-initiated events are often called applets.

Accepted Answer

In object-oriented languages, the procedural modules that depend on user-initiated events are typically referred to as event handlers or methods, not applets. Applets are small application programs that run within a web page or browser.

Question 7

The ____ is the location on your computer screen at which you type entries to communicate with the computer's operating system.

Accepted Answer

The command line is the interface where users type commands to communicate with the computer's operating system.

Question 8

Computer users can expect to see a standard interface in the GUI programs they use.

Accepted Answer

Most GUI (Graphical User Interface) programs follow standard design guidelines, ensuring a consistent look and feel across different applications, which helps users navigate and use software more intuitively.

Question 9

From the 1950s,when businesses began to use computers to help them perform many jobs,through the 1980s,almost all interactive dialogues between people and computers took place at the ____.

Accepted Answer

During this period, the command prompt was the primary means for users to interact with computers, allowing them to type commands directly for the computer to execute. Graphical user interfaces (GUIs) and menus became more common later on.

Question 10

A(n)____ consists of a label placed beside a small square.

Accepted Answer

A check box consists of a label placed beside a small square, allowing users to select or deselect options.

Question 11

GUI programs are frequently called action-controlled because actions occur in response to user-initiated events such as clicking a mouse button.

Accepted Answer

The answer of GUI programs are frequently called action-controlled because...

Question 12

An important advantage of using GUI data-entry objects is that you often can control what users enter by limiting their options.

Accepted Answer

GUI data-entry objects like dropdown menus, radio buttons, and checkboxes allow developers to limit the choices available to users, thereby controlling and validating user input more effectively.

Question 13

Operating system software allows you to use your fingers,a mouse or other pointing device to select screen controls,such as buttons and scroll bars or pictures,also called ____.

Accepted Answer

Icons are graphical representations of programs, files, and commands that users can select using a pointing device or their fingers, especially in graphical user interfaces.

Question 14

Many object-oriented languages offer built-in classes that contain methods you can use to draw geometric figures.

Accepted Answer

Many object-oriented programming languages, such as Java, Python, and C++, offer built-in classes or libraries that provide methods for drawing geometric figures, facilitating the development of graphics and visualization applications.

Question 15

In object-oriented languages,the procedural modules that depend on user-initiated events are often called ____.

Accepted Answer

The answer of In object-oriented languages,the procedural modules that depend...

Question 16

GUI components are excellent examples of the best principles of object-oriented programming;they represent objects with attributes and methods that operate like ____.

Accepted Answer

GUI components encapsulate their functionality, allowing external entities to interact with them through a defined interface without needing to understand their internal workings, akin to the concept of a "black box" in object-oriented programming.

Question 17

When you program in a language that uses GUI components,you need to create them from scratch.

Accepted Answer

Many programming languages that use GUI components provide libraries or frameworks that include pre-built components, allowing developers to use and customize them without creating them from scratch.

Question 18

Within an event-driven program,a component from which an event is generated is the ____.

Accepted Answer

The component from which an event originates or is generated is known as the source of the event. This is because it is the point at which the event is created or triggered.

Question 19

In an event-driven program,you design the screens,define the objects,and define how the screens will connect.

Accepted Answer

In an event-driven program, the design process involves creating the user interface (screens), defining the objects (such as buttons, text fields, etc.), and specifying how these elements interact or connect through events (like clicks or input).

Question 20

A ____ is a rectangular object you can click;when you do,its appearance usually changes to look pressed.

Accepted Answer

A button is a user interface element that is designed to be clicked by the user, causing an action to occur. When clicked, buttons typically change appearance to indicate they have been pressed, distinguishing them from labels, check boxes, and text boxes, which have different behaviors and purposes.
