What is download?
A download is the process of copying data-such as a file, program, music, or video-from a remote server on the internet to your own device (computer, phone, tablet, etc.) so you can use it locally.
Let's break it down
First, you tell your device what you want (e.g., click a link). Your device sends a request to the server where the data lives. The server then sends the data over the internet in small packets. Your device receives those packets, reassembles them, and saves the complete file to your storage.
Why does it matter?
Downloading lets you get software updates, install new apps, watch movies offline, and keep copies of important documents. It turns online resources into something you can access anytime, even without an internet connection.
Where is it used?
- Web browsers when you click “Save” on a picture or PDF
- App stores (Google Play, Apple App Store) for installing apps
- Operating system updates (Windows Update, macOS Software Update)
- Cloud services (Dropbox, Google Drive) when you sync files to your computer
- Gaming platforms (Steam, Epic Games) for installing games
