With time there has been advance developments in Interfaces used by Devices & Peripherals to connect to computer has moved towards univeral standards for INPUT & OUTPUT interfaces. Earlier Keyboard & Mouse used to Connect to serial ports then moved towards PS2 ports and now USB ports. For Display VGA ports used earlier now uses DVI and HDMI interfaces. Printersused parallel ports now uses USB & Ethernet interfaces.Considering new interfaces today PS2, Serial, Parallel and VGA Ports can be considered as Legacy ports.
A "legacy" system is one that is either outdated for most practical purposes, or one that includes older forms of technology.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.
RS-232 serial ports, Parallel ports, and PS2 mouse and keyboard ports. These days, all of these functions can be handled by Universal Serial Bus (USB ) connections.
parallel and serial port
I just purchased new catalytic converters for my 1999 Subaru Legacy Outback. There are three ports for oxygen sensors. They appear to be on the top of the converters.

No, they are not.
No, a legacy is the lasting effect from a person, group or event.
Pretty much, yes. USB ports are smaller and more versatile, and can carry a limited amount of power. Serial and parallel ports are larger and more limited, and cannot be "daisy-chained" like USB devices usually can.
Legacy motherboards (and even some modern ones) would generally have: * An XT / AT or a PS/2 keyboard * A PS/2 mouse connector * 1 to 2 serial ports * 1 to 2 parallel (printer) ports
No.
Most modern laptops lack any sort of "legacy" ports such as serial ports, let alone them having two. Some older laptops did have multiple serial ports, but there's little point in recommending one because there's no guarantee you could find one. There are options for adding serial ports to a laptop, such as a USB to serial adapter, or a PC card with additional serial ports.
Augustus left much of what could be considered a legacy -- his building, military restructuring, certain laws, etc, --but his greatest legacy was the Pax Romana, which enabled the empire to grow and prosper.
