Pipelining is a method of software development that involves writing and testing multiple versions of a software program at the same time. The process is similar to parallel processing, but it works on a more granular scale. Instead of writing one program, you write multiple programs that can run in parallel. The result is that you can write a new version of the program in just a few hours instead of weeks or months.Pipelining is a method of software development that involves writing and testing multiple versions of a software program at the same time.
