Chunk Upload
Noun · Development
Definitions
An upload approach that splits a large file into smaller chunks transmitted separately so progress can be resumed, retried, or parallelized. Chunk uploads are common in browsers and mobile apps because they handle network instability and large files better than one giant request.
In plain English: Uploading a large file in smaller pieces instead of all at once.
Example: "The video uploader used chunk upload so failed transfers could retry only the missing parts instead of restarting a 3 GB file from zero."
