Which of these graphics formats use lossy compression?
Answer: D) JPEG
The JPEG (Joint Photographic Experts Group) format is a common graphics format that creates nicely compressed image files but loses some of the detail of the image during the compression format. Because the detail cannot be recovered through decompression, the format is considered to be “lossy.”
The incorrect answers:
The device independent bitmap (BMP) format is not usually compressed at all. Graphics files in BMP format are usually relatively large when compared to compressed graphics file formats.
A TIFF (Tagged Image File Format) file can be compressed or uncompressed, but the format commonly uses a lossless compression type that preserves the details of the image file.
PNG (Portable Network Graphics) is designed to be a replacement for GIF (Graphics Interchange Format), and its compression method is lossless.

Once a printer or scanner is installed, there’s no guarantee that the devices will work efficiently. Every printer or scanner must be optimized to provide the highest quality performance. In this video, we’ll show you how to optimize printers through tray switching, print spool settings, device calibration, and more. We’ll also show you how optimizing resolution, file formats, and default settings can impact the quality of scanned documents.
