Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallelcomputing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems. Research into artificial intelligence (AI) has led to several other new styles of programming.2.High-level languages are commonly classified asprocedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.四、汉译英题（20分）最著名的互联网例子是因特网。

On the other hand, an interpreter translates and executes the source code line by line. Python and Ruby are examples of languages that use interpreters.2. Object-oriented programming (OOP) is a programming paradigm that organizes data and functions into reusable objects. It focuses on the concept of classes and objects, allowing for code reuse and encapsulation. An example of a programming language that uses OOP is Java, where objects are instances of classes and can interact with each other through methods and attributes.3. The client-server model is a distributed computing architecture wherea server provides services or resources to multiple clients. The clients request and receive these resources through the network. An example of a commonly used protocol within this model is the Hypertext Transfer Protocol (HTTP), which is used for communication between web browsers (clients) and web servers.四、论述题Artificial intelligence (AI) has had a significant impact on various industries. In healthcare, AI is being used for diagnoses and treatments, analyzing medical images, and personalized medicine. For example, AI-powered algorithms can help detect diseases like cancer at an early stage, leading to better treatment outcomes. In finance, AI is utilized for fraud detection, algorithmic trading, and customer service. AI algorithms can analyze large amounts of financial data to identify patterns and make accurate predictions. In transportation, AI is being employed for autonomous vehicles, traffic management, and logistics optimization. Self-driving cars, for instance, use AI algorithms to navigate and make decisions on the road.The implementation of AI in these industries brings about many benefits, such as increased efficiency, improved accuracy, and cost savings. AI systems can process and analyze vast amounts of data much faster than humans, leading to faster and more accurate results. However, there are also challenges to consider. Privacy and security concerns arise as AI systems handle sensitive information. There is also the worry of job displacement, as AI automation may replace certain human tasks. Additionally, ethical considerations need to be addressed, such as bias in algorithms and the potential for AI to be used for malicious purposes.Overall, the impact of AI on various industries is undeniable. It has the potential to revolutionize healthcare, finance, transportation, and many other sectors. However, careful implementation and regulation are necessary to ensure its responsible and beneficial use.。

The read write heads stay on the same track continuously when the disk drive isWorkingF 16. The possible symbols in the binary numbering system are q to 9.F 17. The decimal value of 16 is represented in 4 bits BCD as 00010101.F 18. Alphanumeric versions of BCD commonly use 6,7or 8 bits to represent characters.F 19. A 6 bit alphanumeric code can represent 128 different characters.F 22. Eight bit codes are limited to representing 128 different characters.T23. An extra check (or parity ) bit is often added to each 6, 7, or 8 bit character represented in storage so that it will be possible to detect coding errors that may occur.T24. If a computer uses an odd parity format to detect errors in character codes, thenevery valid character code will always have an odd number of 1 bits.T25. Processor comes with a unique set of operations called an instruction set.F 26. In an instruction, operands specify the function to be performed.T 27. A processor's job is to retrieve instruction from memory and perform step bystep operations,3.3 True or FalseF1 All operating systems on various computers take the same size.F 2 All operating systems were written in a low level language.T3 The user can't use the computers at all if there is no operating system on the computers.F4 The operating system exists in the lowest layer of a computer.T5 The system calls are provided by the operating system.T 6 A computer's operational software defines the schedule of jobs awaiting execution.F7 Though an operating system can schedule the execution of jobs, it does not manage the availability of I/O devices.T 8 The IOCS component of an operating system controls I/O operations.T9 It is a major problem for the operating system to map the logical file concept onto physical storage devices such as magnetic tape or disk.F10 Files can only be direct access on a disk system.T 11 The logic structure and nomenclature of the different operating systems vary considerable.F12 The form of the system prompt is the same for every kind of operating system 13 You must boot the system, before you use a microcomputer.T14 Spooling is an approach to improving system performance by over aping the input of one job with the output of other jobs.T15 Multiprogramming allows time sharing.T1 6 When they first appeared, the microcomputers were provided with the operating system developed for computers.T17 By using the graphical user interface, what the users need to do is to "point and click" in order to accomplish their tasks.T18 The interface introduced by Windows is the object-oriented user interface.T 19.TMicrosoft failed in betting their future on Windows.Multiple Choice1 A computer's operating system is:Da resource managementb error recoveryc memory

interface just like the GUID allowing users to load multiple programs and have them run in thebackground while doing other work in a window in the foreground3.4 True or FalseF1 Flowcharting is used primarily for program design and rarely for systems design.T2 When programming in a procedure-oriented language, you should tell the computer'‘what to do' and 'how to do it'.T3 Assembler-level languages use mnemonics to represent instructions.T4 Machine language instructions are composed of a label, an opcode, and an operand.F5 Machine languages must be converted by a compiler to be used by the computer.F6 High-level languages require that programmers work with individual main storage locations.. 5T7 A compiler is translating program that converts high-level languages into machine language.T9 A flowchart loop indicates the repetitive performance of steeps to process data.T10 None of the computers consists of hardware only.F11 Programs written in high-level language can be executed by the computers without the help of a translator program~T13 Each symbolic instruction has one-to-one correspondence with the machine instruction.T14 Writing a program in a high-level language need not take account of the hardwareof the computer.T 15 The opode of an assembly language instruction specifies the operation that is to beperformed by the microprocessor.T 17 The mnemonic for the instruction is the symbolic representation of the actual binary code that the computer directly executes.T 18 A label is on the left of the assembly language statement.T 21 To enable the computer to solve an application problem programmers have to write programs in order to translate the application concepts into computerconcepts.T 22 A class is defined by grouping a user-defined type with all procedures and function that can be applied to it.T 23 The artificial intelligence research community did not agree with the concepts of object-oriented programming when in its early days.F24 Object-oriented programming languages are absolutely different from the LISP programming language.T 25 A program may produce incorrect output even if it runs OK.T 26 An error will occur if a program wants to use a deleted file.F 27 All the errors can be avoided.T 28 A warning will not terminate the program.T 29 Although we could not avoid all the runtime errors, we must take appropriate action when it happens.Match the following terms to the appropriate definition1 program2 programmer3 machine language4 assembler5 source6 object7 interpreter8 compilerA A computer program that translates an
