What does it mean to 'upload' a file?

Uploading a file refers to the process of transferring a file from a local device—such as a computer or smartphone—to a remote server or cloud service. This action allows users to store their data online, making it accessible from different devices and locations.

The upload process is essential in various applications, such as sharing documents through email or storing files in cloud storage platforms like Google Drive or Dropbox. By uploading files, individuals can manage their data more effectively, collaborate with others, and ensure that information is securely backed up in a networked environment.

In contrast, downloading a file describes the reverse action where data is transferred from a remote source to a local device. Deleting a file refers to removing it from a local device, while backing up a file involves creating a copy of it on an external storage device, rather than transferring it to a remote service.
