it works by finding patterns in the data, using data trees to organize the information and reducing the size of commonly used strings of bits.
it is used when data integrity is important, such as programs or consistently high resolution image/video.]]> 2018-09-28 09:52:36 UTC https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286867973 What is compression harrysturman5 https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286868429 To compress a file is to reduce the overall size. This is done by an algorithm that will find and remove as much redundant data as possible. An example of this would be plain text in a word processing document being replaced by numbers or another kind of identifier. The identifiers are saved as a key in the newly compressed document, for example the word "and" may be saved as the number 5, and the more times the word is used the more efficiently compressed the file will be.

Binary files such as applications and disk images can also be compressed, again with an algorithm which locates repeating patterns. However once a file like this is compressed it must be decompressed before use, using a file decompression application.]]> 2018-09-28 09:54:43 UTC https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286868429 What is lossy Compression? Lossy file compression results in lost data and quality from the original version. Lossy compression is typically associated with image files, such as JPEGs, but can also be used for audio files, like MP3s or AAC files. ilyaswakily17 https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286868503  ]]> 2018-09-28 09:54:59 UTC https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286868503 Why do we need compression? james_herne https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286868574 Files usually take up a considerable amount of space so compressing the file decreases the file size so you can save more files on your computer. It is useful to compress files on a website so users with slower internet speed can get onto the site with little to no problems.]]> 2018-09-28 09:55:24 UTC https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286868574 Can vectors be grouped harrysturman5 https://padlet.com/harrysturman5/d3t642d3rdzv/wish/286881071 Yes
