哪位英语高手帮忙翻译一下,谢谢啦

红外通信标准的广泛兼容性可为PC设计师和终端用户提供多种供选择的无电缆连接方式，如掌上计算机。笔记本计算机。个人数字助理设备和桌面计算机之间的文件交换；在计算机装置之间传送数据以及控制电视。盒式录像机和其它设备。
3.红外通信技术开辟数据通信的未来
目前，符合红外通信标准要求的个人数字数据助理设备。笔记本计算机和打印机已推向市场，然而红外通信技术的潜力将通过个人通信系统(PCS)和全球移动通信系统(GSM)网络的建立而充分显示出来。例如，诺基亚公司最近宣布它与加拿大的AST公司签订了提供无线通信系统的合同，将这一技术产品投放市场，并在加拿大产业界目前许可经营的PCS数字通信基础设施上运行。
由于红外连接本身是数字式的，所以在笔记本计算机中不需要调制解调器。便携式PC机有一个任选的扩展插槽，可插入新式PCS数据卡。PCS数据卡配电话使用，建立和保持对无线PCS系统的连接；扩展电缆的红外端口使得在PCS电话系统和笔记本计算机之间容易实现无线通信。
由于PCS.数字电话系统和笔记本计算机之间的连接是通过标准的红外端口实现的，所以PCS数字电话系统可在任何一种PC机上使用，包括各种新潮笔记本计算机以及手持式计算机，以提供红外数据通信。而且，由于该系统不要求在计算机中使用调制解调器，所以过去不可能维持高性能PC卡调制解调器运行所需电压的手持式计算机，现在也能以无线方式进行通信。
基于Windows 95的PC支持红外通信连接标准，可与符合标准的外设通信，并可与支持该标准而运行Windows 95的其它的 PC机通信。只要是把计算机对着目标设备，并发送数据，红外通信技术就可使 Windows 95的用户连接外设和其它的基于 Windows 95的PC机。
预计，Windows 95环境下的红外数据通信连接还可与现有的软件和驱动器兼容，所以用户勿需改动现有的系统，即可采用该技术。红外技术还支持"即插即用",可使Windows 95识别红外外设，自动配置必需的驱动器。
红外通信标准的开发者还在设想在机场和饭店等地点使用步行传真机和打印机，在这些地方，掌上计算机用户可以利用这些外设而勿需电缆。银行的ATM(柜员机)也可以采用红外接口装置。
预计在不久的将来，红外技术将在通信领域得到普遍应用，数字蜂窝电话。寻呼机。付费电话等都将采用红外技术。红外技术的推广意味着膝上计算机用户不用电缆连接的新潮即将到来。
[影响]
由于红外通信具有隐蔽性，保密性强，故国外军事通信机构历来重视这一技术的开发和应用。这一技术在军事隐蔽通信，特别是军事机密机构。边海防的端对端通信中将发挥出重要的作用。正如前面所述，它还将对计算机技术产生冲击，对未来数据通信产生重大影响。

A wide range of infrared communications compatibility standards for the PC provides a wide range of designers and end users for non-cable connection of choice, such as handheld computers. Notebook computer. Personal digital assistant devices and desktop computers to exchange files between; in the transmission of data between computer devices and the control of the television. Cassette recorders and other equipment.

3. Infrared communication technologies open up the future of data communications

At present, infrared communications standards in line with the personal digital assistant device data. Notebook computers and printers has been to the market, however, the potential for infrared communication technology through personal communications system (PCS) and Global System for Mobile Communications (GSM) networks and fully displayed. For example, Nokia recently announced that it and Canada signed the AST to provide wireless communications system contract, the technology market and industry in Canada is currently operating permit PCS digital communications infrastructure to run.

Since the infrared connection is digital, so no need in a notebook computer modem. Portable PC machine has an optional expansion slot can be inserted into the new PCS data card. PCS data card with telephone use, to establish and maintain systems for wireless PCS connection; expansion of the infrared port makes cable PCS telephone system in the notebook computer and wireless communication easy to achieve.

As a result of PCS. Digital telephone system and the connection between the notebook computer through the standard infrared port, so PCS digital telephone system can be in any machine on a PC, including laptop computers and a variety of trendy hand-held computers, to provide infrared data communications. Moreover, since the system does not require the use of a modem in the computer, so the past is impossible to maintain high-performance PC Card modem required voltage to run the hand-held computers, are now able to communicate wirelessly.

The PC-based Windows 95 to support the standard infrared communication links, can be sub-standard peripherals and communications, and with the support of the standards of the other running Windows 95 machine of PC communications. As long as it is at the target device to the computer and send data, infrared communication technology would enable Windows 95 users to connect other peripherals and the PC based on Windows 95 machines.

Expected, Windows 95 environment to connect the infrared data communications can be used with existing software and drivers are compatible, so users Needless to change the existing system, you can use the technology. Infrared technology also supports the "plug and play" will enable the identification of infrared peripherals Windows 95 automatically configure the necessary drivers.

Infrared communication standards are also envisaged the development of airports and hotels in locations such as fax machines and printers to use on foot, in such places, handheld computer users can use these peripherals and cables Needless. Bank's ATM (automatic teller machine) can also be used infrared interface device.

Expected in the near future, infrared communications technology will be widely used, digital cellular phones. Pagers. Pay phones have infrared technology will be used. Infrared technologies means that the laptop computer users do not have cable connected to the upcoming fashion.

[Affect]

Since the infrared communication with the hidden, confidentiality, and it is foreign military communications agency that has always attached importance to the development and application of technology. This technology in the military covert communications, particularly in institutions of military secrets. Border and coastal defense of the end-to-end communications will play an important role. As previously mentioned, it will impact on computer technology for the future have a significant impact on data communications.
