"Upload" refers to the process of transferring data or files from a local device, such as a computer or smartphone, to a remote server or cloud storage. This action allows users to share documents, images, videos, and other types of content over the internet, making them accessible from different devices and locations. In the context of technology, uploading is commonly used in various applications and platforms, including social media, email, and file-sharing services. For example, when a user posts a photo on Instagram or sends a file via Google Drive, they are engaging in the upload process to share their content with others.
