问题 综合

读图7-l-3及材料回答有关问题。

材料:几年前,邮政和电信还是一家,垄断着全国的邮电业务。后来,通过改革,邮政与电信分家,各自经营各自的业务。随着改革的深入,电信业又重组为移动局、多媒体局、电话局等多家,并且垄断局面也开始被打破了。随着联通、铁通等企业经营电信业务,电信业呈现“多国鼎立”之势,各种电信费用明显下降。而邮政的垄断局面一直未被打破,邮政费用不断攀升。

(1)邮政的业务主要有   ,影响邮政通信的自然灾害有   等。

(2)电信的业务主要有   ,影响电信通信质量的自然因素是   

(3)从图7-l-3中可以看出,邮政网络是由组成,邮件的传递一般至少需要   个邮局参与。

(4)北京的小李与拉萨的小张进行了电话交谈。在这个通信过程中所使用的电信设备有    (    )

A.终端设备——电缆,传输设备——电话机,交换设备——电话交换机

B.终端设备——电话机,传输设备——电话交换机,交换设备——光缆

C.终端设备——电话交换机,传输设备——电缆,交换设备——电话机

D.终端设备——电话机,传输设备——光缆,交换设备——程控交换机(5)如果G邮局为国外邮局,F邮局为国内邮局,则F邮局的职能是   

答案

(1)传递信函、邮寄包裹 台风、暴雨、山洪(2)传递符号、文字、图像、语言 地形障碍 (3)邮局、邮路 2 (4)D (5)互换各类国际邮件

本题是道综合性很强的题,主要考查邮政和电信的职能、网络的组成等知识。邮政的主要业务是传递信函、邮寄包裹,除此之外还有订购报纸和杂志、发(订)邮票、办理汇兑、代缴电费和煤气费等业务。邮政网络由邮局、邮路组成。所以,凡是影响铁路、公路、水路、航空等运输的自然因素都会影响邮政通信。电信的主要业务是传递符号、文字、图像、语言。影响其通信质量的主要是地形因素。电信设备包括终端设备、传输设备及交换设备三部分。行业垄断是当今社会的一个热门话题,它是在特定的历史条件下产生的,但随着社会的发展,它的弊端将越来越明显。
