　　一、判斷對錯

　　1. The software system is the physical equipment that you can see and touch.

　　2. Typically, a data value is set to zero to represent FALSE and 1 value for TRUE.

　　3. In the earliest general-purpose computer, most input and output media were magnetic disks.

　　4. Supercomputers are largest, fastest, and most expensive computer available.

　　5. A computer system consists of hardware system and software system.

　　1. The data bus always receives data from the CPU, and the CPU never reads the data bus.

　　2. Main memory holds whatever programs and data are available for immediate use by the CPU.

　　3. Dynamic RAM does not have to be refreshed.

　　4.Dot-matrix printer work by squirting tiny droplets of liquid ink at the paper.

　　5. The auxiliary memory is very small, relatively expensive, and has very high access speed.

　　1. Shift registers operate in serial fashion all the bits of the word at a time.

　　2. RISC processors have larger instruction sets that often include some particularly complex instructions.

　　3. SIMD represents an organization that includes many processing units under the supervision of a common control unit.

　　4. Parallel processing is established by distributing the data among the multiple functional units.

　　5. RISC is a complex instruction set computer.

　　1. A number of different algorithms can exist for solving a computational problem, and each of these algorithms could have a same running time complexity.

　　2. The divide-and-conquer algorithm is a bottom-up technique that usually begins by solving the smallest subproblems, the dynamic programming solves problems in a top-down fashion.

　　3. An important property of arrays is that their size and shape are constant.

　　4. If all of the elements stored in a list are of the same type, then the list is said to be heterogeneous. However, if different types of elements are stored in the list, then the list is said to be homogeneous.

　　5. A queue is a dynamic set that obeys the LIFO property.

　　1. The computer hardware recognizes only assembly language instruction.

　　2. A program written in the assembly language of one microprocessor can run on a computer that has a different microprocessor.

　　3. Assembly languages are platform-independent, but high-level languages are not platform-independent.

　　4. The 4GLs are also called nonprocedural languages.

　　5. Each assembly language instruction corresponds to one unique machine code instruction.

　　二、完形填空

　　This chapter introduces digital computer, data types, the evolution of computers, and types of computers. 1 is known to all, it’s hard to find a field in 2 computers are not being used. Digital computer, also called electronic computer or computer, is a digital system that 3 various computational tasks. Digital computers use the 4 number system, which has two digits: 0 and 1.

　　By using various coding 5 , groups of bits can be made to represent not only binary numbers 6 other discrete symbols, such as decimal digits or letters of the alphabet. A computer system consists of hardware system and software system. Programs tell the hardware what to do. 7 software is designed to accomplish real-world tasks in fields such as accounting, entertainment, and engineering. Computers are usually 8 into four broad categories: microcomputers, minicomputers, mainframe computers, and supercomputers. It’s hard to give a 9 definition to each type because computer speeds and storage 10 change rapidly.

　　1. A. As B. It C. As it D. That

　　2. A. what B. which C. where D. when

　　3. A. performs B. carries C. makes D. integrates

　　4. A. decimal B. binary C. Arabian D. American

　　5. A. technique B. technology

　　C. techniques D. technologies

　　6. A. instead of B. rather than

　　C. but also D. as well

　　7. A. Application B. System C. Word D. Excel

　　8. A. put B. made C. conducted D. classified

　　9. A. precious B. progress C. proceeding D. precise

　　10. A. capacities B. capable C. capabilities D. capacity

　　1.A 2. B 3. A 4. B 5. C 6. C7. A 8. D 9. D 10.A
