To understand the value of parallel downloading, one must first grasp how traditional downloads work. By default, most browsers download a single file using a single TCP connection. This approach is reliable but conservative; it mimics a single-lane highway where only one data packet can travel at a time. In contrast, parallel downloading—also known as segmented or multi-threaded downloading—splits a file into several smaller chunks and downloads these chunks simultaneously using multiple connections. The browser then reassembles them on the fly. This technique exploits the fact that modern internet connections (broadband, fiber, 5G) often have spare bandwidth and can handle concurrent streams without congestion. Opera’s implementation of this feature, derived from its Chromium core, allows up to several parallel requests per download, reducing the total time spent waiting for sequential packet acknowledgments.
