单项选择题 In the following essay, each blank has four choices. Choose the best answer and write down on the answer sheet. In recent years, there has been a dramatic increase in the range of media used to 1 information. Initially, communication was limited to simple forms of 2 such as voice and paper. This century, however, has witnessed the introduction of a greater variety of media types such as the telephone and visual forms of media. In the latter part of the century, this trend has accelerated and there is now a wide range of media types available to convey information. These advances provide a great opportunity for new developments in a range of areas such as education and commerce. However, there are also a number of problems associated with the growth of 3 in society. In particular, there is a great danger of creating information 4 . This problem can be seen, for example, in business where executives are required to make decisions based on an ever increasing variety and volume of information. 5 problems are also occurring in areas such as government, health care and education.
The software architecture of a program or computing system is the structure or structures of the system, which comprise software______, the externally ______ properties of those components, and the relationships between them. The architecture is not the operational software. Rather, it is a ______ that enables a so, ware engineer to: analyze the ______ of the design in meeting its stated requirements, consider architectural alternatives at a stage when making design changes is still relatively easy, and reduce the ______ associated with the construction of the software.
For each blank, choose the best answer from the four choices and write down on the answer sheet. It is claimed that Al applications have moved from laboratories to the real world. However, conventional von Neumann computers are 34 for Al applications, because they are de- signed mainly for numerical processing. In a larger yon Neumann computer, there is a larger ratio of memory to processing power and consequently it is even less efficient. This 35 remains no matter how fast we make the processor because the length of the computation becomes dominated by the time required to move data between 36 and memory. This is called the yon Neumann 37 . The bigger we build the machines, the worse it gets. The way to solve the problem is to diverse from the traditional architectures and to design special ones for Al applications. In the research of future Al architectures, we can take advantages of many 38 or currently emerging concepts. in computer architecture, such as dataflow computation, stack machines, tagging, pipelining, systolic array, multiprocessing, distributed processing, database machines, and inference machines.
