Lossy= Is generally more effective but when opening file it loses some data. This is most noticeable in compressed pictures

Lossless= Is the most common method of compression and loses none of the data

Lossless data compression is a method of reducing the size of a file without losing any of the original data. This means that the compressed data can be decompressed back to its original form without any loss of information. Common algorithms for lossless compression include ZIP, gzip, and PNG.

Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.

What are the areas of compression?

The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.


Detail in data compression tech?

Data compression techniques are used to reduce the size of files and data for efficient storage and transmission. Common methods include lossless compression, which preserves all data accurately, and lossy compression, which sacrifices some data to achieve higher compression rates. Examples of compression algorithms include ZIP for general purpose compression, JPEG for image compression, and MP3 for audio compression.


What are facts about compression?

Compression is the process of reducing the size of data to save storage space and transmission bandwidth. There are two main types of compression: lossless compression, where no data is lost during the process, and lossy compression, which sacrifices some data quality for further reduction in file size. Popular compression algorithms include ZIP, JPEG, MP3, and MPEG.


What best explains the term compression?

Compression refers to reducing the size of a file or data to save storage space or facilitate faster transmission. It works by encoding the data in a more efficient way, removing redundancy or using algorithms to minimize the amount of space the data takes up. Compression can be lossy, where some data is permanently removed, or lossless, where the original data can be reconstructed precisely.


How does the compression work in PNG?

PNG uses lossless compression to reduce the file size of images without losing any quality. It achieves compression by using filter algorithms and entropy encoding methods to represent the image data more efficiently. This compression process helps to maintain the integrity of the image while reducing the amount of data needed to store it.
