MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -JPEG and GIF are types of image formats. JPEG uses lossy compression algorithm where the image may lose some of its data, whereas GIF uses lossless compression algorithm where there is no data loss.

Detailed explanation-2: -The JPEG image file, commonly used for photographs and other complex still images on the web with no transparency, is generally compressed using lossy compression. Using JPEG compression, the creator can decide how much loss to introduce, and how much of a trade-off is acceptable between file size and image quality.

Detailed explanation-3: -Because GIF is a lossless data compression format, meaning that no information is lost in the compression, it quickly became a popular format for transmitting and storing graphic files.

Detailed explanation-4: -JPEG or JPG compression is the act of reducing the size of a JPEG image file. While other image formats feature lossless compression, meaning that the picture loses no quality with compression, JPG features lossy compression, which does.

Detailed explanation-5: -JPEG: JPEG stands for Joint Photographic Experts Group. .jpg and . jpeg extensions are used to store image in this format. It uses lossy compression algorithm, it means some of the image data is lost. GIF: GIF stands for Graphics Interchange Format.
