- Lossy compression - Wikipedia
It is possible to compress many types of digital data in a way that reduces the size of a computer file needed to store it, or the bandwidth needed to transmit it, with no loss of the full information contained in the original file A picture, for example, is converted to a digital file by considering it to be an array of dots and specifying the color and brightness of each dot

- Lossless compression - Wikipedia
Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information Lossless compression is possible because most real-world data exhibits statistical redundancy [1] By contrast, lossy compression permits reconstruction only of an approximation of the original data, though usually with greatly
- Data compression ratio - Wikipedia
Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2 10 = 0 8, often notated as a percentage, 80% For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:

The green, orange and yellow lines indicate how surface temperatures will likely respond if leading carbon emitters begin to reduce reliance on fossil fuels Without immediate curbs, temperatures are set to follow the red track, and increase between 3 2 and 5 4 degrees Celsius by 2100 The green line shows how we can minimize warming if

Sumatra PDF is written mainly by two contributors: Krzysztof Kowalczyk and Simon Bünzli [1] The source code is developed in two programming languages, mostly in C, with some components in C++ The source code is provided with support for Microsoft Visual Studio [18]As it was first designed when Windows XP was the current version of Windows, Sumatra initially had some incompatibilities with
