Question 51
How do you change the physical location of the pointer (cursor) on the screen?
The mouse is a pointing device. When you move the mouse across a flat surface, the sensors transmit that motion to the computer, which translates it into the corresponding movement of the pointer on the display screen. Clicking and dragging are actions performed *after* the pointer is positioned.

Question 53
After you have finished typing a letter or designing a brochure, how can you see exactly what your document will look like on paper before you commit to printing?
Print Preview is a feature that generates a digital representation of the final printed page. It allows you to check for layout errors, margin issues, or cut-off text, helping to save ink and paper by ensuring the document is correct before it is physically printed.

Question 55
Tools found in a drawing or painting program, used to create geometric shapes like lines, rectangles, ovals, and polygons, are collectively known as 'drawing tools.'
Drawing tools are the digital equivalents of physical drafting tools. They allow users to create 'vector' or 'raster' shapes by clicking and dragging on the canvas, providing a way to create precise geometric elements within a graphic design or art application.

Question 56
The process of making files smaller to save storage space and then returning them to their original size for use is commonly known as:
Compression software (like WinZip or 7-Zip) uses algorithms to remove redundancies in data, 'zipping' it into a smaller file. To use the file again, it must be 'unzipped' (extracted), which restores the data to its original, uncompressed state.

Question 57
Image resolution (the clarity and detail of a digital image) is primarily dependent upon which two factors?
An image can only be as clear as the data stored in the file (PPI/DPI) and the capability of the hardware displaying it. For example, a high-resolution photo will still look blurry if printed on a low-quality printer or viewed on an old, low-resolution monitor.

Question 58
Microsoft Word is classified as which type of software?
Application software is designed to help the user perform specific tasks—in this case, word processing. This is distinct from System Software (like Windows or macOS), which manages the computer's hardware and provides a platform for applications to run.

Question 59
What is the full meaning of the acronym GUI?
A Graphical User Interface (GUI) allows users to interact with electronic devices through visual indicators like icons, menus, and windows, rather than text-based command lines. This makes computers much more intuitive and accessible to the general public.

Question 60
In a design or publication software, what does it mean if a specific object or image is 'transparent'?
Transparency (or opacity) determines how much of the underlying content shows through an object. If an object is 50% transparent, it blends with whatever is behind it on the 'stacking order,' allowing the colors or images of the lower layers to be visible.
