How does lossy and lossless compression work?
With lossless compression, every bit of data originally in a file remains after it is uncompressed, and all the information is restored.
Lossy compression reduces a file by permanently eliminating certain information, especially redundant information..
Text compression techniques
Because GIF is a lossless data compression format, meaning that no information is lost in the compression, it quickly became a popular format for transmitting and storing graphic files..
Text compression techniques
DCT is the most widely used form of lossy compression, for popular image compression formats (such as JPEG), video coding standards (such as MPEG and H. 264/AVC) and audio compression formats (such as MP3 and AAC)..

What is Data Compression? Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size.
Fundamentally, it involves re-encoding information using fewer bits than the original representation..
What are examples lossless data compression?
Lossless compression file types.
PNG.
This is a pixel-based image format that offers high-quality graphics. BMP.
Another image file type used for storing and printing high-quality digital photos. RAW.
These powerhouse files are one of the most common camera image formats. GIF. ZIP. WAV..What is data compression and lossless compression in computer networks?
There are broadly two types of data compression techniques—lossy and lossless.
In lossy, the insignificant piece of data is removed to reduce the size, while in lossless compression, the data is transformed through encoding, and its size is reduced..
What is the difference between lossless and lossy data compression?
With lossless compression, every bit of data originally in a file remains after it is uncompressed, and all the information is restored.
Lossy compression reduces a file by permanently eliminating certain information, especially redundant information..
What is the difference between lossy and lossless medium?
While studying EM wave propagation, you must have heard the terms like lossy medium and lossless medium.
Let us first see the definitions of lossy and lossless medium.
Lossy medium:- It is the medium, where the EM wave loses its power.
Lossless medium:– It is the medium, where the EM wave does not lose power..
