IEEE1394B Port (Bilingual) (4)
IEEE1394 is a high speed serial bus like SCSI but has simple connections and hot-
plugging capabilities like USB. The interface 1394A has a bandwidth up to 400 Mbits/
sec and 1394B up to 800 Mbits/sec. They both can handle many 1394 devices on the
same bus. IEEE1394 is also used in high-end digital equipment and should be marked
"DV" for Digital Video port. This is a bilingual port so it can function with both 1394A &
1394B devices at the speeds listed above respectively.
Hi-Speed USB Port (.0/1.1) (5)
The USB (Universal Serial Bus) port is compatible with USB 2.0 or USB 1.1 devices
such as keyboards, pointing devices, cameras, hard disk drives, printers, and scanners
connected in a series up to 12Mbits/sec (USB 1.1) and 480Mbits/sec (USB 2.0). USB
allows many devices to run simultaneously on a single computer, with some peripherals
acting as additional plug-in sites or hubs. USB supports hot-swapping of devices so that
most peripherals can be connected or disconnected without restarting the computer.
Security Lock Port ()

compatible Mobile System security products. These security products usually include
a metal cable and lock that prevent the Mobile System from being removed from
a fixed object. Some may also include a motion detector to sound an alarm when
moved.
