1、软件水平考试(中级)网络工程师上午(基础知识)试题模拟试卷 2及答案与解析 1 在双绞线布线后要进行测试,一般情况,下面 (64)不是测试的项目。光纤测试的内容不包括 (65)项目。 ( A)近端串扰 ( B)拓扑结构 ( C)开路或短路 ( D)错对 ( A)衰励损耗 ( B)长度 ( C)近端串扰 ( D)时延 3 ATM when referring to computers is a dedicated, connection switching technology that organizes digital data into 53-byte(69)units and trans

2、mits them over a physical(70)using digital signal technology. ATM is capable oftransniitfing at speeds of 155 or 622 MBit/s and faster. ( A) minuteness ( B) toothful ( C) cell ( D) spot ( A) medium ( B) media ( C) matter ( D) plastid 5 In the following essay, each blank has four choices. Choose the

3、most suitable one from the four choices and write down in the answer sheet. A socket is basically an end point of a communication link between two applications. Sockets that extend over a network connect two or more applications running on(66)computers attached to the network. A socket(67)two addres

4、ses:(68). Sockets provide a(69)communication channel between one or more systems. There are(70)sockets separately using TCP and UDP. ( A) unique ( B) separate ( C) same ( D) dependent ( A) is made of ( B) composed of ( C) is composed of ( D) is consisted of ( A) Email address and IP address ( B) MAC

Cho

6、ose the best answer and write-down on the answer sheet. Microwave communication uses high-frequency(71)waves that travel in straightlines through the air. Because the waves cannot(72)with the curvature of the earth, they can be(73)only over short distance. Thus, microwave is a good(74)for sending da

7、ta between buildings in a city or on a large college campus. For longer distances, the waves must be relayed by means of “dishes“ or(75). These can be installed on towers, highbuildings, and mountain tops. ( A) optical ( B) radio ( C) electrical ( D) magnetic ( A) reflex ( B) distort ( C) bend ( D)
