Why did Baidu's network disk data get stuck at the last second?

Because the displayed progress bar is 99%, it is not necessarily true. Programmers' progress bars simply can't accurately reflect the computer situation. The so-called 50%, 80% and 90% are only approximate figures and forecasts. It can be said that the progress bar we see and the actual progress are two different things.

For some quantifiable projects, the progress bar can basically match the reality, but different hardware resources and background programs will occupy each other's resources, so it is difficult for computers to allocate and run continuously. When you download the movie to 99%, it is a difficult "1% moment" to open a big game or a small task gets stuck. In fact, this 1% will happen at any time, but we are impressed by the last 1%.

The origin of progress bar design;

1896, the polish economist cairol adami Jecky made a chart called timetable, and put forward the early concept of progress bar, but there was no specific application at that time. By 1979, this Buddy Mitchell model put forward a progress bar in the doctoral thesis.

In the paper, he said: the progress bar can monitor the system behavior in a complex computer environment. To put it bluntly, the progress bar can intuitively show what the computer is doing and to what extent. It is precisely because the progress bar can express the characteristics of computer's complex calculation process with the simplest patterns and numbers that it has gradually become popular in major operating systems and become one of the classic symbols of computers.
