Which file format is typically used for digital images?

• A. PDF
• B. JPEG
• C. DOCX
• D. HTML

Answer: (B)

The choice of JPEG as the typical file format for digital images is correct because JPEG (Joint Photographic Experts Group) is specifically designed for compressing and storing photographic images. This format allows for high-quality images to be saved with much smaller file sizes, making it ideal for use on the web and in digital photography. Its compression algorithm reduces the image size effectively while maintaining a level of image quality that is generally acceptable for most users.

In contrast, while PDF files can also contain images, they are primarily designed for document exchange and not solely for image storage. DOCX is the file format commonly used for Microsoft Word documents, focusing on text and document formatting rather than images. HTML is a markup language used for creating web pages; it structures content but does not define an image file format. Therefore, JPEG is the most suitable format among the options for storing and sharing digital images.
