Compressing files or images enables you to (sometimes dramatically) decrease the memory space that file will take up. Without going into to too much detail, it works by 'approximating' the information in the file, thereby lowering the detail and filespace. However, compression also reduces the quality of the file, possibly corrupting it if it is compressed too much!

What are the Advantages of arithmetic coding over Huffman coding?
1.the compression ratio is higher compared to huffman coding. 2.efficiency is greater comparatively. 3.Redundancy is much reduced.
FAT32 supports compression of individual files and folders?
FAT32 does not support compression of filesor folders
What type of compression substitutes special characters for repeating patterns?
Lossless compression is the correct answer :)
What is the unknown compression method used in this file?
The unknown compression method used in this file is not specified or identified.
How does compression effect images?
Any type of compression will ideally reduce the size of an image. There are two types of compression which describe how they affect images:"Lossy" compressionThis type of compression reduces the size of the image by removing some data from it. This generally cause, effect the quality of the image, which mean it will reduce your image quality."Lossless" compressionThis type of compression reduces the size of the image by changing the way in which the data is stored. Therefore this type of compression will make no changes in your image.
