Data Compression - A Level Computer Science
Image Compression Why do we need image compression? Let’s take the image above. This image is a relatively small 2 Megapixel image, with dimensions of 2133 x 974 pixels. This image is a 24 bit RGB image, meaning that it’s file size should be: 2133 x 974 x 24 = 49.8 Megabits Divide by 8… Read More »Data Compression

Rossellini Harris on Instagram: "ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common. This format was originally created in 1989 and was first implemented in PKWARE, Inc.’s PKZIP utility,[2] as a replacement for the previous ARC compression format by Thom Henderson. The ZIP format was then quick
