The CPU would have to wait for the i/o to finish before it can proceed to another process. Although the CPU allowed multiple programs to run, they had to be run in sequence. This could cause a pileup because one process had to be completed before another one could be started. Without DMA, the purpose of mutiprogramming is defeated.
