Chapter Summary

• Common port types available on most computers include serial, parallel, USB, FireWire, IrDA, and wireless.

• When you troubleshoot connections, ensure that the device is enabled and listed as working properly in Device Manager. If Device Manager shows that the device is enabled and is working, the problem is most likely in the application. If the device is not listed as working properly when you view it in Device Manager, ensure that the device is turned on, that the port is configured properly, and that the cable is in working order. You can also use the Windows troubleshooters to help isolate the problem.

• Mobile and handheld devices vary in functionality and purpose. Some mobile devices act as remote terminals, some act as movable displays, and some simply hold data.

• Mobile and handheld devices connect to computers in a variety of ways, including wirelessly, by using a USB or FireWire port, or by slower methods such as a serial port.

• Connecting a handheld or mobile device to the computer requires the proper port to be available, and the BIOS must offer the required support. Software must be installed so the computer and the peripheral device can communicate.
