So here's the deal: If a computer can run each macro instruction as several micro-instructions then it can translate the 32/64/128-bit instructions into their equivalent 8-bit instructions and cascade them horizontally to produce the same result as a G4/G5-series instruction set using less power than it would take to do the same thing on the original G4-series processor.

需要注意到那个起中控作用的PowerPC内核，它是用来协调所有处理单元的工作的。就目前的技术来说，我想每个处理单元的任务应该是根据所要处理的任务事先hardcode的。也许将来，能够在运行时，根据所处理的具体任务实时决定每个处理单元的运行逻辑，就像transmeta所宣传的那样，那就非常非常的动态了。

We selected from 222 students at first grade in a primary school as subjects. A One to One intervention was given in the subjects by using self-made program computer programs. This study is composed of two experiments. The first experiment discusses the effect of self-explanation which guided by different direct instruction in problem solving on procedural learning, procedural transfer and conceptual understanding. The purpose of this experiment was to test whether self-explanation can promote transfer and which is the most the most effective combination of self-explanation and instruction. The second experiment, based on the results of the first experiment, compared the effect of self-explanation of different types in problem solving on procedural learning, procedural transfer and conceptual understanding. There are two methods: explain aloud, explain without voice. The purpose was to compare which effect is better?

以222名小学一年级学生为被试，经过筛选后，采用自编的计算机程序对被试一对一实验，研究由两个实验组成，实验一探讨问题解决中不同教授条件下引导的自我解释，对程序的学习、程序的近迁移、程序的远迁移和概念知识的影响，探讨是否自我解释能够促进迁移以及与哪一种教授条件相结合是更有效的；实验二根据实验一的研究结果，比较问题解决中引导的不同形式的自我解释，对程序的学习、程序的近迁移、程序的远迁移和概念知识的影响，探讨出声的自我解释和不出声的自我解释哪个效果更好。

Human brain function similar to the central processing unit installed on the motherboard on the above, it has a superhuman memory and rapid calculation function of precision, it can be scheduled in accordance with the procedures for people to not hesitate to complete the instruction, as well as network traffic as the memory, it can provide more paths and channels to the computer, the faster the computer more efficient, to let the computer voice would also like to assemble a deal with the sound card sound files, as the screen reader software At the same time, prompted the need for sound playback, sound card, therefore the request is relatively high, the best selection of full-featured dual-channel sound card.

类似人脑功能的中央处理器就安装在主板上面，它具有超人的记忆能力和精确快速的运算功能，它能够按照人们预定的程序毫不犹豫地去完成各项指令，还有就象交通路网的内存，它能够提供更多的路径和通道给计算机，使得计算机的运算速度更加快捷，要让计算机能够发出声音还要装配一个处理声音文件的声卡，由于读屏软件所需要同时播放提示声音，因此声卡的要求比较高，最好选用功能齐全的双声道声卡。

China Computer Correspondence School was established in 1984, in 1987 the State Council Leading Group for Science and Technology approved to engage in a nationwide computer professional higher education institutions, the country developed a computer application more than 500,000 people, known as the "National flagship computer education ", on behalf of the State Education Department the authority of an independent computer certificate issued under the" country "brand name college.

In this paper, the concept of network security and security structures of OSI and Internet is introduced, and various threats confronting the computer network are also discussed. Several kinds of network information security technologies, including firewall technology, virtual private network, intrusion detection system, data encryption technology, identity authentication and security protocol etc. are also examined. The security of internal network is the biggest problem in the construction of each network. The solution to this problem lies in setting up a firewall. The theory of a firewall and the approach to its actualization is studied. Intrusion detection system, an important part of the computer network security system, has gained extensive attention. IDS monitors the computer and network traffic for intrusion and suspicious activities. It not only detects the intrusion from the extranet hacker, but also the intranet users. The emergence of virtual private network paves the way for realizing secure connection of LAN quickly and at a relatively low cost. The concept, function, key techniques, including the tunnel technology, and the ways to realize VPN are expounded in this paper. Also introduced is the data encrypt network technology, which is called the soul of computer network security, such as digital digest, digital signature, digital certificate, digital encrypt arithmetic and so on. At the same time, the principle and the process of implementing network security by digital certificate and digital signature, the basic principle and characters of security protocols, and finally, three of the security protocols, concerning the security problems in network, IPsec, SLL and SET are analyzed in detail Computer network system should be a system of dynamic defence, both dynamic and static, passive as well as active, and even offensive, combined with management and technology.
