Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is meant by lossless compression?
A
Removes data to reduce the file size. When the file is uncompressed, only a part of the original information is still there (There will be some loss of quality). Examples:mp3 and jpeg.
B
As the file size is compressed, the quality remains the same-it does not get worse. Also, the file can be decompressed to its original quality. Examples:GIF and FLAC. File sizes are larger than lossy.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Lossless compression uses an algorithm to shrink the image without losing any important data. Essentially, it rewrites the file to make it more efficient-resulting in a smaller storage or transfer size. One way the algorithm does this is by replacing non-essential information and storing them in an index file.

Detailed explanation-2: -What is Lossless Compression? answer choices. No information is lost but file size is increased. There is no loss of information at all after compression. Files which have the exact same data after compression.

Detailed explanation-3: -Lossy compression reduces an image file size by permanently removing less critical information, particularly redundant data. Lossy compression can significantly reduce file size, but it can also reduce image quality to the point of distortion, especially if the image is overly compressed.

Detailed explanation-4: -Lossless compression means that as the file size is compressed, the picture quality remains the same-it does not get worse.
