Question Request for identification of video interfaces

[waghela]

What are the interfaces marked with the letter A and B called?
Are they video and audio inputs or outputs?
Is it possible to connect to a monitor to view the PC image?

Those aren't video interfaces. Those are Firewire 400 (B) and 800 (A) ports.

Thank you very much! I became clear.
