Serial Advanced Technology Attachment Not sure in which context you mean but the normal meaning of SATA is Serial ATA which is the type of transfer architeture insife the PC from the motherboard to the Hard drive. It is a newer faster information transfer type which will make PC run faster and transfer information internally faster in the future.

A "legacy" system is one that is either outdated for most practical purposes, or one that includes older forms of technology. A "legacy-free" PC is one that does not include older ports that would be necessary to support much older equipment, such as parallel ports, ISA slots, serial ports, PS/2 ports, and sometimes even VGA.

Most modern projectors do not use serial or parallel ports; instead, they typically connect via HDMI, VGA, or other digital interfaces. Serial and parallel ports were more common in older devices but have largely been replaced by these newer technologies for better video quality and ease of use. Some legacy projectors may still support these older connections, but they are becoming increasingly rare.

Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
Many things, from teletypes to disk drives.
