What interface for these three ?

My freind asked me what interface these following devices would use and i told him ,


Keyboard > serial
Printer > parallel
Disk Drive > Parallel

is this right or wrong ?


Please help

The keyboard can be USB or PS2 too as well as the printer can be USB.

forgot to mention it's between serial and parallel so is the above right and what about the disk drive ?

Disk drive is a bit vague:

Hard? if so is it IDE or SCSI
Floppy?
CD/DVD

internal or external?

Cheers

Wel If the Question is HOW IS THE DATA TRANSFERED BETWEEN THE DEVICES Then the answer is

Code:

---

Keyboard ps2/AT/USB = Serial
Mouse ps2/serial/USB = Serial

Printer            25pin    = Parallel
                        USB    = Serial

HDD                *IDE    = Parallel
                        SCSI    = Parallel
                        SATA    = Serial  (this is the new fast breed)

Now I hope this has helped you with your homework

Cheers
