考题 第一组An automatic system usually consists of a control system and an information system. A control system is a system which measures the condition of some entity and, with the information, governs the state of a variable; i.e., speed, temperature, pressure, position, etc. The open-loop system is the simplest form. a control system may assume. It is distinguished from the closed-loop system by the lack of an input which measures the state of the controlled variable; such an input is called a feedback. In modern ships the open-loop system has practically disappeared and the closed-loop system which operates with a feed-back is extensively used. An information system serves the parallel function of monitoring system or plant performance. The monitoring function may serve a number of purposes; specifically it may indicate values of controlled variables to guide remote control operations, warn of off-limit conditions and provide record of performance. In many cases a visual and audible alarm may be provided to warn of off-limit conditions on board ship and, associated with this, the important variables will be recorded on demand. The automatic control system can be more sophisticated by incorporating digital-processing equipment, that is, a computer. This computer is usually fed with signals from all sensors. It scans the values of the sensors and generates alarm signals for off-limit conditions, acting as a super-supervisor. Sometimes, it can even make necessary and take the necessary action to optimize performance without human intervention.The closed-loop system differs from the open-loop system byA.the lack of a feedbackB.the presence of a feed backC.the lack of a computerD.the presence of a computer

考题 The primary advantages of a Client/Server system arise from splitting the processing between the client system and the database server. Since the bulk of the database processing is done on the back-end, the speed of the DBMS isn't tied to the speed of the(31).The major disadvantage of Client/Server system is the increased cost of(32) and support personnel who maintain the database server. There is also the issue of(33)with so many parts comprising the entire C/S system; Murphy's Law can kick in-the more pieces that compose the system, the more pieces that can fail. It's also harder to track down problems when the system(34). And it can initially take longer to get all the components set up and working together. All this is compounded by the general lack of experience and expertise of potential support personnel and programmers, due to the relative newness of the technology. As C/S system become more common, this problem should abate.Therefore the C/S system is more(35).A.networkB.operating systemC.personal computerD.workstation

考题 The objective of (请作答此空) is to determine what parts of the application software will be assigned to what hardware. The major software components of the system being developed have to be identified and then allocated to the various hardware components on which the system will operate. All software systems can be divided into four basic functions. The first is (72). Most information systems require data to be stored and retrieved, whether a small file, such as a memo produced by a word processor, or a large database, such as one that stores an organization's accounting records. The second function is the (73), the processing required to access data, which often means database queries in Structured Query Language. The third function is the (74), which is the logic documented in the DFDs, use cases, and functional requirements. The fourth function is the presentation logic, the display of information to the user and the acceptance of the user's commands. The three primary hardware components of a system are (75). A.architecture design B. modular design C. physical design D.distribution design
