MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -In lossy compression, the data in a file is removed and not restored to its original form after decompression. Specifically, data is permanently removed, which is why this method is also known as irreversible compression. This data loss is not usually noticeable.

Detailed explanation-2: -DCT is the most widely used form of lossy compression, for popular image compression formats (such as JPEG), video coding standards (such as MPEG and H. 264/AVC) and audio compression formats (such as MP3 and AAC).

Detailed explanation-3: -For graphics, video and audio signals, lossy compression is most commonly used. Audio and video can be compressed to 5% of their original size using lossy compression, but the data loss is seldom detectable to the human eye or ear at this level.

Detailed explanation-4: -The most common example of lossy compression is JPEG, an image compression format used extensively on the web and in digital photography. This widely recognized format is supported by numerous tools and applications.
