Dosya Sıkıştırması: Basit Tanım
File compression is the process of reducing the size of a file or group of files so they take up less storage space and transfer faster over the internet.
Compression works by finding patterns in data and replacing repetitive sequences with shorter codes. A ZIP file might replace 100 repeated characters with a small code that means “repeat this character 100 times”.
Dosya Sıkıştırması Nasıl Çalışır
All compression algorithms look for redundancy in data. If your text file contains the word “the” 500 times, a compression algorithm can replace each instance with a 2-bit code, dramatically reducing file size.
There are two types of compression: lossless (where no data is lost - perfect for documents and code) and lossy (where some data is permanently removed - used for images, audio, and video where perfect reproduction is not required).
Dosya Sıkıştırma Örnekleri
ZIP files
ZIP uses DEFLATE compression to package multiple files into one smaller archive. Opening a ZIP restores the exact original files.
JPEG images
JPEG uses lossy compression to reduce image file size by discarding visual information that the human eye barely perceives.
MP3 audio
MP3 uses psychoacoustic compression to remove audio frequencies humans cannot easily hear, reducing file size by 90%.
PDF compression
PDF files can be compressed by reducing image quality within the PDF and removing unnecessary metadata.
