Parallel ATA (PATA) is an interface standard used to connect storage devices, such as hard drives and optical drives, to a computer's motherboard. It allows for the transfer of data between the devices and the computer using multiple data lines, enabling faster communication compared to older technologies. PATA typically supports two devices per channel, using a 40 or 80-pin ribbon cable. Introduced in the 1980s, PATA was widely used in personal computers until the rise of Serial ATA (SATA), which offers improved performance and simpler cabling. While PATA is now largely outdated, it played a crucial role in the development of modern storage technologies.
