When I started reading Arcangel's article, On Compression, I was able to understand the Lossless compression and the Lossy compression. As we upload things to the blog, we compress it into a zipped file in order to keep our files from losing data, especially when it is from processing. Compressing the file also saves data and sends it quicker because there is less to deconstruct, compared to sending a regular file. Now I understand why some files take longer to send. When it is a Lossy compression, there is a chance that data will be lost, but I see it as useless information that won't be missed. However, it is important information. By compressing files, we are able to save space.
As Arcangel's explained the process, it was confusing to understand, especially with all the math and formulas. When he used the postage system as an example I was able to understand the whole process better. The file is deconstructed into smaller pieces, and then is reconfigured, which he described as input and output. The JPEG he used shows the deconstruction of the file. However the output he got was the same image but not fully reconstructed. Sometimes, if you open a JPEG on your desktop, you can see the file reconstruct itself with the small squared.
Although I did not understand the math part of On Compression, I enjoy reading about the history of the name JPEG, "Joint Photographic Experts Group." When I look at the name, JPEGs are joint block but together to recreate an image, which I stated earlier. Everything that Arcangel's briefly touched on is hard to understand but does show how compressed files are transferred. I see it as Legos being rebuilt every time it is opened but it may not be the exact same pieces. However, it still makes the same thing.
