This splitting is slightly different. It is a big file being cut into smaller pieces to help with its storage and transmission operations.

Splitting during downloading is called multithreaded download which takes advantage of the servers' ability to communicate the address of the current data chunk being sent and to resume. That way you can start downloading multiple parts of a file simultaneously which helps increase speed by utilising full throughput (per thread data transfer limits are rare, but another thing it sidesteps to increase speed).

'Full throughput ?'

well. tcp/ip starts with a low transfer rate and increases it until it starts seeing error of missing packets which is supposed to be from packet dropped in transit due to buffer full / more in than out. Now the servers starts lowering rate until the errors disappear. This lowering is often aggressive and leaves room for higher rate.

So both are splitting file. but one is on the fly and might use compression.
