SATA and PATA Full Form
What is the full form of SATA and PATA?
SATA and PATA are both a connector which is used to connect the secondary storage or external devices to the computer. PATA stands for Parallel Advanced Technology Attachment which is only an interface used to connect secondary storage devices like hard disk and optical drive. Western Digital and Compaq first introduced it in 1986. SATA later replaced it.
SATA stands for Serial Advanced Technology Attachment and is also an interface (pin) that connects hard drives, and optical drives to the computer motherboard. It was introduced in 2001 when PATA gradually lost its demand by the Serial ATA Working Group. SATA has more advantages than PATA, which makes it more in demand.
