Viruses, which are pieces ofcode that can replicate themselves, can quickly use all available system memory, damage or destroy data stored on the hard drive, and permanently affect theperformance of the programs they infect. Several commercial virus-scanning programs are available for purchase, and most bulletin board services (BBSs)archive freely distributed virus-scanning programs that you can download with a modem.Before you install a program, read its documentation to learn how the program works, what hardware it requires, and what its defaults are. A program usuallyincludes installation instructions in its accompanying documentation and a software installation routine on its program diskette(s) or CD(s).The software installation routine assists you in transferring the appropriate program files to your computer's hard drive. Installation instructions may providedetails about how to configure your operating system to successfully run the program. Always read the installation instructions before running a program'sinstallation routine. You may be instructed to modify some operating system start-up files, such as config.sys and autoexec.bat, or the installation routinemay modify start-up files automatically.When you run the installation routine, be prepared to respond to prompts for information about how your computer's operating system is configured, whattype of computer you have, and what peripherals are connected to your computer.TAPITelephony Application Programming Interface (TAPI) enables Windows-based applications to operate with a wide variety of telephony devices, including voice,data, fax, video, and so forth. TAPI applications require a TAPI service provider (TSP), which is a software driver that allows TAPI applications to communicatewith different types of TAPI hardware.Microsoft® Windows® 2000, Windows XP, and Windows NT® provide a TSP called Unimodem, which is a "universal" modem service provider that supports awide range of commonly used modems. For more information on Unimodem, see your Windows documentation. When using a TAPI device other than amodem, such as a Private Branch Exchange (PBX) or a voice processing card, you will need a TSP provided by the manufacturer of the device.The TAPI system board connector uses a 4-pin cable to interface your internal TAPI-compliant expansion card with the audio system in your computer. Tolocate the TAPI system board connector, see "System Board Components." TAPI-compliant cards using the standard TAPI connector are supported. Forexample, you can connect your modem to the TAPI connector and then use your audio speakers and microphone as a speakerphone. The microphone carriesyour voice into the computer and then through the TAPI system board connector to your modem card. The caller's voice enters through the modem card to theTAPI system board connector and then out to the speakers. You can also use this configuration to record and play sound files over the phone.Installing a TAPI Device1.
