S-Video is an analog port, not digital, so "serial" and "parallel" terms do not apply to it.
parallel and serial port
parallel port if you want to know why go to it140 if you know what that is.
No. Its a parallel port
USB port (Universal Serial Bus) replaces the parallel port
USB port, serial port, parallel port.
An S-Video Port.
give the difference between serial port and parallel port
This cannot be done. The LPT port is a digital parallel printer port used mostly to interface with printers. The LPT port has a very low data transfer speed and is considered by many to be obsolete. The S-video is an analog port and sends a signal similar to a composite video signal. The two are apples & oranges, and there is no known hardware which can make that conversion. Nor will there likely ever be.
Usually, because a serial port doesn't have to deal with the problem of signal skew that can jumble the data on a parallel port and gets worse proportional to distance.
No. VGA port is not either serial or parallel port. It is a different interface. If you need a serial output, you need a VGA to serial converter.
A serial port only allows a single bit of data through at a time. A parallel port allows multiple bits of data through at a time.
It's kinda like a perpendicular serial port, but instead of intersecting it just kinda lines up.
