摘要：对于【网络工程师】软考考试而言，试题无疑是最重要的学习资料之一。在软考备考过程中，吃透试题、掌握试题所考知识点、熟悉试题的出题思路，对我们提升分数的效果是最明显的，通过对试题的反复练习，还可以查漏补缺。今天，给大家带来【2014年5月 网络工程师 上午题】部分试题的详解，一起来看看吧~



1、The traditional way of allocating a single channel among multiple competing users is to chop up its ( 本题 ) by using one of the multiplexing schemes such as FDM (Frequency Division Multiplexing). If there are N users, the bandwidth is divided into N equal-sized portions, with each user being assigned one portion. Since each user has a private frequency (  ), there is no interference among users.When there is only a small and constant number of users, each of which has a steady stream or a heavy load of (   ), this division is a simple and efficient allocation mechanism. A wireless example is FM radio stations. Each station gets a portion of the FM band and uses it most of the time to broadcast its signal.However, when the number of senders is large and varying or the traffic is (   ), FDM presents some problems. If the spectrum is cut up into N regions while fewer than N users are currently interested in communicating, a large piece of valuable spectrum will be wasted. If more than N users want to communicate, some of them will be denied (   ) for lack of bandwidth.„„
