U2 L5: Compressing Data

Lesson 5: Compressing Data | Made on October 22nd

data compression algorithms

attempt to represent digital data in ways that preserve the accuracy of the data while using significantly less space

storage space optimization

data compression reduces the amount of space required to store files and info, allowing to store more data in the same amount of space

internet travel

smaller files can be transmitted more faster, leading to more faster uploads and download, reduces waiting times, and improved overall data transfer efficiency

conserving bandwidth

when data is compressed= takes up less space=less data needs to be sent over the network

improved user experience

compressed data allows for smoother streaming & faster loading times, enhancing the user experience by reducing the buffering & lag

lossy compression

a type of data compression technique that reduces the file size of data by permanently discarding some amount of info that’s considered less important/noticeable

lossy compression is commonly used in scenarios such as: ___

images, audio, video

examples of lossy compression are: ___

JPEG, MP3, AAC, H.264, H.265, and in video games, reduces the size and quality of textures, models and other assets to improve game performance

lossless compression

a type of data compression technique that retains all of original data allowing for perfect reconstruction of the original content when data is compressed

examples of lossy compression are: ___

text-based documents (PDFs, word processing files, spreadsheets, archiving), backup purposes, reducing size of program files, executables and libraries, scientific & medical imaging
