1.● Although a given waveform. may contain frequencies over a very broad range, as a practical matter any transmission system will be able to accommodate only a limited band of （71） . This, in turn, limits the data rate that can be carried on the transmission （72） . Asquare wave has an infinite number of frequency components and hence an infinite （73） . However, the peak amplitude of the kth frequency component, kf, is only 1/k, so most of the （74） in this waveform. is in the first few frequency components. In general, any digital waveform. will have （75） bandwidth. If we attempt to transmit this waveform. as a signal over any medium, the transmission system will limit the bandwidth that can be transmitted.（71）A. frequencies B. connections C. diagrams D. resources（72）A. procedure B. function C. route D. medium（73）A. source B. bandwidth C. energy D. cost（74）A. frequency B. energy C. amplitude D. phase（75）A. small B. limited C. infinite D. finite（71）A. frequenciesB. connectionsC. diagramsD. resources（72）A. procedureB. functionC. routeD. medium（73）A. sourceB. bandwidthC. energyD. cost（74）A. frequencyB. energyC. amplitudeD. phase（75）A. smallB. limitedC. infiniteD. finite

第1题：

A transport layer protocol has several responsibilities. One is to create a process-to-process (program-to-program) communication; TCP uses port (71) to accomplish this. Another responsibility of a transport layer protocol is to create a (72) and error-control mechanism at the transport level. TCP uses a sliding (73) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (74) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (75) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver.

第3题：

Without proper safeguards,every part of a network is vulnerable to a security breach or unauthorized activity from（71）,competitors,or even employees.Many of the organizations that manage their own（72）network security and use the Internet for more than just sending/receiving e-mails experience a network（73）—and more than half of these companies do not even know they were attacked.Smaller（74）are often complacent,having gained a false sense of security.They usually react to the last virus or the most recent defacing of their website.But they are trapped in a situation where they do not have the necessary time and（75）to spend on security.

第4题：

Both bus and tree topologies are characterized by the use of multipoint (71) ．For the bus，all stations attach，through appropriate hardware (72) known as a tap，directly to a linear transmission medium，or bus．Full-duplex operation between the station and the tap allows data to be transmitted onto the bus and received from the (73) ．A transmission from any station propagates the length of the medium in both directions and can be received by all other (74) ．At each end of the bus is a (75) ，which absorbs any signal，removing it from the bus．
