    Howdy. In my A+ certification class (mostly PC stuff, ew, I know:( ) me and a buddy of mine we wondering...

    A bus like ATA133 is supposed to be 133 Mb/s, right? Firewire 400 is supposed ot be 400 Mb/s. Firewire 800 is supposed to be 800 Mb/s. How come computers are using Serial ATA, SCSI, ATA 133, etc, when there's Firewire? It's faster, right? Or is it?

    and I've always wondered why my Power Mac G4 (AGP) has a 6 pin Firewire port on the motherboard. Thanks.

    ATA133 is 133 MB/s and FireWire 400 is 50 MB/s. That's bytes and not bits.

    ATA 133 translates into 1066 Mb/s. I know it's 1064 but everthing else in computing likes numbers like 1066. Note these are bits.

    B = bytes
    b = bits

    8 bits = 1 byte
