Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be reconstructed, in exchange for better compression rates.
Lossless data compression is used in many applications. For example, it is used in the ZIP file format and in the Unix tool gzip. It is also often used as a component within lossy data compression technologies (e.g. lossless mid/side joint stereo preprocessing by the LAME MP3 encoder and other lossy audio encoders).
Lossless compression is used in cases where it is important that the original and the decompressed data be identical, or where deviations from the original data could be deleterious. Typical examples are executable programs, text documents, and source code. Some image file formats, like PNG or GIF, use only lossless compression, while others like TIFF and MNG may use either lossless or lossy methods. Lossless audio formats are most often used for archiving or production purposes, with smaller lossy audio files being typically used on portable players and in other cases where storage space is limited and/or exact replication of the audio is unnecessary.
Holding on to pieces, of our summer, going by
On a wall of memories, at the edges of my mind
Whoa, they used to tell a story
But they're just paper to me now
Whoa, they used to say 1000 words
But now they can't be heard
We ran out of time, said goodbye too soon
Pictures being faded, of the summer nights in june
Blurry all the memories, still remember what was true
Pictures they are fading, changing, leaving
A silhouette of you
Foot stamps on the pavements
I'm retracing every corner we turned to see
If we could have kept these moments from burning
To ashes and dust
Whoa, they used to say 1000 words
But now they can't be heard
We ran out of time, said goodbye too soon
Pictures being faded, of the summer nights in june
Blurry all the memories, still remember what was true
Pictures they are fading, changing, leaving
A silhouette of you
A silhouette of you
A silhouette of you
A silhouette of you
We ran out of time, said goodbye too soon
Pictures being faded, of the summer nights in june
Blurry all the memories, still remember what was true
Pictures they are fading, changing, leaving
We ran out of time, said goodbye too soon
Pictures being faded, of the summer nights in june
Blurry all the memories, still remember what was true
Pictures they are fading, changing, leaving
