What's the significant of the DMA IDE setting?

Taking the advice of the forum members here, I changed my IDE settings from PICO to DMA. I do see some increase in performance. What is the significance of these settings?

it takes the cpu out of the equation when transferring data to and from IDE devices. It is very important when burning DVD at 4x or ripping from dvd as quickly as possible. It also increases overall system performance quite a bit as you already noticed. Basically, without DMA the cpu is playing middle-man for data going to and from the hard drive and other devices on the IDE interface. DMA stands for Direct Memory Access, which simply means the data goes straight from the drive/device to system memory bypassing the CPU's attention. This allows to CPU to pay more attention to everything else going on/vying for its attention.
