Reduce File Sizes For Storage Or Transmission
Muhtasari
A holiday video, a folder of photos, a detailed report packed with images: all of them can be too big to email or slow to upload. File compression solves this by squeezing a file into fewer bytes so it takes less storage space and travels faster. The clever part is choosing how to squeeze it, because some methods keep every last detail while others throw a little away to make the file even smaller.
In this lesson you will learn why we reduce file sizes for storage and transmission, how compression with .zip and .rar works, and the crucial difference between lossless compression, which restores the exact original, and lossy compression, which discards some detail permanently. You will learn which file types use each method and how to choose the right approach for a given task.
