Summary 📝

Compression software is used to reduce the size of files, making them quicker to transfer and easier to store. This is especially useful when sending files online or saving space on devices. 

There are two main types of compression: lossy and lossless. Lossy compression removes some data permanently, which can lower the quality of images, audio or video. 

Lossless compression keeps all the original data and allows the file to be fully restored when uncompressed. 

Compression helps speed up file uploads, downloads, and can reduce data usage. Knowing which type of compression to use depends on the content and the need to preserve quality. 

Key Learning Points 📌

1. Compression reduces file size for faster transfer and storage.
   
   

2. Lossy compression removes data permanently (e.g., JPEG, MP3).
   
   

3. Lossless compression keeps all data, allowing full restoration (e.g., ZIP, PNG).
   
   

4. Compression saves storage space on devices.
   
   

5. It also reduces time and data used when uploading or downloading files.
