Translation:截至 2007 年，几乎所有的主板都在后面有至少4 个USB 端口，在主板上有至少2 个内置连接点以连接可能被置于计算机机箱中的额外的前置端口。,1.1 Computer Motherboard,Exercises I. Read the following statements carefully, and decide whether they are true (T) or false (F) according to the text. _1The motherboard is sometimes alternatively known as the mainboard, system board, the logic board and backplane. _2A motherboard provides physical sockets and slots as some peripheral interfaces. _3BIOS is stored in non-volatile memory chips. _4In modern computers it is increasingly common to integrate some peripherals into the motherboard itself. _5By combining many functions on one PCB, highly-integrated motherboards are more complex and more expensive.,1.1 Computer Motherboard,II. Choose the best answer to each of the following questions. 1. Which of the following is NOT attached to the motherboard via edge connectors and cables in a typical desktop computer? AExternal storage BControllers for video display CMicroprocessors DPeripheral devices,C,1.1 Computer Motherboard,II. Choose the best answer to each of the following questions. 2. Which of the following components can be used to attach peripheral devices to the motherboard as plug-in cards or via cables? APower connectors BExpansion Card Slots CCPU Sockets DNon-volatile memory chips,D,1.1 Computer Motherboard,II. Choose the best answer to each of the following questions. 3. In the following descriptions , which is RIGHT about the functions of CPU socket? AA CPU socket houses a CPU on motherboard BA CPU socket provides heat sink CA CPU socket forms an interface both with the CPU and the PCB DAll above,B,1.1 Computer Motherboard,III. Translating. 1. Original: In personal computers, a motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals Translation: 2. Original CPU socket provides many functions, including a physical structure to support the CPU, support for a heat sink, facilitating replacement (as well as reducing cost), and most importantly, forming an electrical interface both with the CPU and the PCB Translation:,1.2 Multi-core Processors,Introduction Terminology Advantages Disadvantages,1.2 Multi-core Processors,Complex Sentences 1. Original: A many-core processor is a multi-core processor in which the number of cores is large enough that traditional multi-processor techniques are no longer efficient largely due to issues with congestion in supplying instructions and data to many processors. Translation:多核处理器是一种具有多核的处理器，在多核处理器中，核的数量足够多而传统的多处理器技术已不再能胜任，这主要是由于向多个处理器提供指令和数据时的拥塞问题造成的。,1.2 Multi-core Processors,Complex Sentences 2. Original: The proximity of multiple CPU cores on the same die allows the cache coherency circuitry to operate at a much higher clock-rate than is possible if the signals have to travel off-chip. Translation:由于位于同一芯管上的几个CPU 距离很近，高速缓存的同步要比在多个芯管间CPU 上的高速缓存同步快得多。,1.2 Multi-core Processors,Exercises I. Read the following statements carefully, and decide whether they are true (T) or false (F) according to the text. _1Processors were with only one core in the early stage of development. _2A multi-core processor implements multiprocessing in a single physical package. _3This article uses both the terms “multi-core”and“dual-core”to refer to multiple physically separate CPU. _4AMD and Intel are two top manufacturers in the area of multi-core processor. _5The ability of multi-core processors to increase application performance depends on the use of multiple threads,1.2 Multi-core Processors,II. Choose the best answer to each of the following questions. 1. Which of the following is RIGHT about the multi-core processors? ACores in multi-core processors are designed to share cache and memory BMulti-core architecture is able to balance the work across multiple cores for each application CThe improvement in performance gained by the use of a multi-core processor entirety depends on the hardware designed DA system with n cores is always more effective than the ones that have only one core,B,1.2 Multi-core Processors,II. Choose the best answer to each of the following questions. 2Which of the following is WRONG about the ad
