[单选题]●有关曼彻斯特码编码的正确叙述是 (24) 。(24)

将时钟与数据取值都包含在信号中

解析：【解析】曼彻斯特码就是为了克服不归零码所带来的直流漂移。曼彻斯特码的编码规则是：每一位的中间有一个跳变，这个跳变既作为同步时钟，又作为数据，从高到低的跳变表示"1"，从低到高的跳变表示"0"。

[多选题]●Extreme Programming (XP) is a discipline ofsoftware development with__(71) of simplicity, communication, feedback and courage. Successful software development is a team effort - not just the development team, but the larger team consisting of customer, management and developers. XP is a simple process that brings these people together and helps them to succeed together. XP is aimed primarily at object-oriented projects using teams of a dozen or fewer programmers in one location. The principles of XP apply to any (72) project that needs to deliver quality software rapidly and flexibly.An XP project needs a (73) customer to provide guidance. Customers, programmers, managers, are all working (74) to build the system that's needed. Customers - those who have software that needs to be developed - will learn simple, effective ways to (75)what they need, to be sure that they are getting what they need, and to steer the project to success.

[单选题]In recent years, one of the more popular topics for panel discussions at computer conferences and trade(61)has been the "RISC versus CISC" debate.RISC processors feature a small number of instructions that each executes in(62)machine cycle. CISC processors use complex instructions that can take several cycles to execute.The RISC versus CISC debate won't be decided by panel discussion; it will be won in the marketplace. And the deciding factor may have little to do with(63)of instructions and registers and more to do with parallelism.Since their conception, RISC processors have been evolving toward micro parallelism, incorporating parallel-processing features(64)the processor, RISC processors feature pipelining, whereby many instructions can be decoded while one instruction executes. RISC processors, however, are moving toward pipelines for each unit of the processor.CISC processors also employ pipelining. They have many integer instructions that execute in one cycle, but the varying execution times of CISC instructions(65)the effectiveness of parallelism.
