In computer graphics, digital photos and scanned images are typically stored in which type of graphics format when they have extensions such as .bmp, .png, .jpg, .tif or .gif?

Introduction / Context:
Digital photos and scanned images are everywhere in modern computing, from mobile phone cameras to document scanners and web images. This question tests basic knowledge of how such images are represented and stored on a computer. When you see file extensions like .bmp, .png, .jpg, .tif, or .gif, you are dealing with a specific type of graphics representation, and understanding this helps build a foundation for topics like image editing, web design, and computer graphics.

Given Data / Assumptions:

• The question mentions digital photos and scanned images.
• Typical file extensions listed are .bmp, .png, .jpg, .tif, and .gif.
• We are asked to identify the type of graphics in which these kinds of files are stored.
• Options include Bitmap, Pixels, Plane, a combined option, and a generic distractor.
• We assume the learner knows that these formats store images as grids of tiny picture elements.

Concept / Approach:
Digital images can be represented as bitmap (raster) graphics or vector graphics. Bitmap graphics store images as a grid of individual pixels, where each pixel holds color information. Almost all common photograph and scanner formats, such as .jpg and .png, are bitmap formats. While the word pixel is related, pixels are the basic elements inside a bitmap image rather than the name of the graphics type. Therefore, the correct concept to match these file extensions is bitmap graphics.

Step-by-Step Solution:
Step 1: Note that the extensions .bmp, .png, .jpg, .tif, and .gif are all standard image file types used for photos and scanned images.Step 2: Recall that these formats store images as a matrix or grid of pixels, where each pixel represents color information at a particular location.Step 3: Recognise that such a grid based representation is called bitmap or raster graphics.Step 4: Compare this with the options. Bitmap is the graphics type, Pixels are the individual elements inside the bitmap, and Plane is not the usual term for this context.Step 5: Conclude that Bitmap is the only option that correctly describes the type of graphics used for the given extensions.

Verification / Alternative Check:
Another way to verify the answer is to recall how image editors like Microsoft Paint, Photoshop, or GIMP describe images. They usually refer to these formats as bitmap or raster images. Vector formats, such as .svg or .eps, are used for scalable illustrations and logos, not for typical photos from cameras or scanners. Since the question lists only formats traditionally associated with bitmap images, selecting Bitmap is consistent with how these tools and textbooks classify them.

Why Other Options Are Wrong:
Pixels are the tiny dots that make up a bitmap image, but the images themselves are not called pixel graphics in usual terminology. Plane is not a standard term for this classification and does not describe common image file types. The option Both Bitmap and Pixels is misleading because pixels are part of a bitmap, not a separate graphics type alongside it. None of these is incorrect because Bitmap is indeed the correct and widely recognised term.

Common Pitfalls:
Learners sometimes confuse the idea of pixels with the entire graphics type and may think pixels is the right answer because images are made from pixels. Others may think of vector graphics, which are built from lines and shapes described mathematically, but these usually have different file extensions. To avoid such confusion, remember that everyday photos and scanned images are almost always stored as bitmap graphics, especially when they use the listed extensions.

Final Answer:
Digital photos and scanned images with extensions such as .bmp, .png, .jpg, .tif, or .gif are stored as Bitmap graphics.
