Lossy and Lossless Compression

Compression allows Internet users sending large files to reduce the overall bits and bytes in a file so that it can be transmitted faster over slower internet connections or take up less space on a disk. We have to different types of compression methods, Lossy and Lossless compression. Explain in your own words the difference between these two methods.

  1. Lossless compression is used to reduce the storage size and is reconstructed from the compressed data
    Lossy compression is when it's compressed and parts of it is lost and will never be realized by human eye

  2. Lossy compression shrinks the quality that the human eye is not capable of noticing thus altering its quality. Loseless Compression temporarily alters the quality but upon opening the image, the quality comes back with no interference.

  3. Lossless Compression is when a file that has been compressed can be decoded back into its original form with zero loss of information, Lossy compression is is after compression, the original file cannot be brought back again.

  4. Loseless Compression Is When A File Gets Compressed So It Can Get Sent To A Person Faster But The Person Gets The Original File , Not The Compressed File.

    Lossy Compression Is When A File Gets Compressed And It Stays Compressed.

  5. Lossy compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. Lossless compression is data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.

  6. Lossless compression causes every bit of the file to remain the same as if is uncompressed and lossy compression permanently alters the file.

  7. Lossless compression compresses the information and can decoded back when received by the recipient but unfortunately with lossy compression it appears as the compromised info that was sent which mean it cannot recover its original file.

  8. Lossless compression every bit of a file to remain the same just like it was never compressed when it is decoded and lossy does a compression that permanently change a file make it like new.

  9. Lossless and lossy compression are terms that describe whether or not, in the compression of a file. Lossless allows for all of the original data to be recovered whenever the file is uncompressed again and lossy it ends up eliminating all the “unnecessary” bits and pieces of information in the original file to make it smaller when compressed.

  10. Lossy compression is when for example an image is compressed whether it be in the aspects of color or detail embedded in the picture the quality of the picture drops but is sent at a much faster rate. Lossless compression does the same thing how ever the regression in the image is only for the sending process the image when received will revert back to its original state prior to compression. The compression aspect is solely for speedy delivery.

  11. Lossy compression is when the something is reduced in the image you are sending and is not visible to the human eye. However, Lossless compression is when data is only momentarily altered to allow it to send but the original data will be visible upon opening the data. Nothing will change.

  12. Vanessa Mariscal:

    Lossy Compression is used when storing, handling, and transferring content. It is used in order to reduce the size of a file or data, removing partial data which is not completely significant.
    Lossless Compression works hand in hand with lossy compression by reconstructing the file into it's original data form in order for the receiver to obtain a perfectly reconstructed file.

  13. lossless compression is the temporary reduction of an image while lossy compression is the process of extracting certain parts of the image that is not noticeable to the human eye.

  14. lossy compression are files being stored, losing data and quality from the original file and lossless compression is data store allowing Restoration from the original file with out losing any data or quality. The data being loss are thumbnails think of it as a puzzle you have the entire puzzle to make it fit in a frame you have to take either the corners pieces of the puzzle of the small details in order to compress or it the puzzle piece

  16. Lossy compression is when the photo is compress and you can't notice it
    Lossless compression is when the picture is compressed while is being sent, but when you receive it is reverted back to the original

  17. The difference between lossy compression and lossless compression is that with lossy compression you replace a word that is repeated more than once with an image and lossless compression is when you compressed an image that is large and makes it smaller when you send the image and you can't tell where anything was missing.

  20. lossless compression techniques that encompasses guarantee generate an exact duplicate of the input data stream after a compression cycle expansión.en change Lossy compression uses the same certain amount of information using less of it, but It is impossible an accurate reconstruction of the original data. This is because, rather than save an exact copy, only an approximation is saved. This approach takes advantage of the limitations of human perception to hide the distortion introduced.
