in the usb port or in the back on the monitor or in the headphone port
If you are using windows XP, Microsoft integrated a feature called "Plug-and-Play" allowing you to simply plug your new monitor into the pronged video output port in the back of your tower and use it instantly.
Composite video out has better performance than S-Video.
If a CRT monitor has either a DVI or HDMI port then it can be connected to a DVI output port of a computer or other source. CRT monitors are now hard to find and few of them have any kind of digital input. The likely answer to the question is "no" but of course it depends on the features of the monitor
There is a combined headphone and optical digital audio output (minijack) socket. On the current iMacs it is the first socket on the back.
All connections are on the rear of the Mac Mini. There is an HDMI port we you can plug in your monitor. There's also a thunderbolt port or you can plug-in any monitor equipped with a thunderbolt output. There's also 4 USB ports and one ethernet port
A USB port takes a device that can be both an input and an output device. For instance, an external USB hard-drive can be written to (by keyboard) and data can be extracted (put up on the monitor or sent to a printer).

A USB port is both an input and an output.
Yes, it is possible to have dual monitor output using one DVI port on a graphics card and another from the motherboard, but it depends on your system's configuration. If your CPU has integrated graphics and the motherboard supports it, you can enable both outputs in the BIOS/UEFI settings. However, this setup may not provide optimal performance for graphics-intensive tasks, as the monitors would be using different graphics sources. Always check compatibility and settings for your specific hardware.
