What is the significance of "jpg 100" in Illustrator and how does it impact the quality of images?

In Illustrator, "jpg 100" refers to the quality setting when saving an image as a JPEG file. A higher quality setting, such as 100, results in a larger file size but better image quality with less compression artifacts. This impacts the clarity and sharpness of the image when viewed, making it suitable for high-resolution printing or detailed graphics.
