4．Datasheets Datasheets are available for most ICs giving detailed information about their ratings and functions. In some cases example circuits are shown. The large amount of information with symbols and abbreviations can make datasheets seem overwhelming to a beginner, but they are worth reading as you become more confident because they contain a great deal of useful information for more experienced users designing and testing circuits.

If you need to remove a chip it can be gently prised out of the holder with a small flat- blade screwdriver. Carefully lever up each end by inserting the screwdriver blade between the chip and its holder and gently twisting the screwdriver. Take care to start lifting at both ends before you attempt to remove the chip, otherwise you will bend and possibly break the pins.

• Pentium 4 - Introduced in 2000 (1.4-3.4GHz)
Latest Pentium architecture started out with a 400MHz system bus and 256KB L2 cache (later increased to 800MHz and 2MB). The first models contained 42 million transistors, used the 0.18 micron process and came in 423pin and 478-pin PGA packages. Intel's first Pentium 4 chipset was the 850 and supported only Rambus memory (RDRAM), but subsequent chipsets switched to DDR SDRAM.

八进制和十六进制系统通常在计算机通信和计算机储存信息时用。
计算机只能处理二进制系统或其它系统如八进制和十六进制中的二进制编码，所以十进制系统必须先转换成这些数字系统才能有计算机处理。
当计算机对所给的信息处理完毕后，输出的信息是以非十进制的形式打印或显示出来。
所以这些输出信息必须再转换成为十进制系统。
（3）Answer the following questions with English (40points)1.Electronics is a part of the larger field of electricity. The basic principles of electricity are also common to electronics. Modern advances in the field of computer, control system, communications have a close relationship with electronics. The field of electronics includes the electron tube, transistor, integrated circuit and so on2、Eight types3、The integrated circuit is sometimes called an IC. An integrated circuit is a small electronic device made out of a semiconductor material. The first integrated circuit was developed in the 1950s by Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor.At today’s level of development, it might comprise more than ten thousand separate electronic elements including elements of many functions, such as diodes, transistors, capacitors and resistors.模拟试题二答案a)Decide whether each of the following statements is true (√)or false (ⅹ)(20 points)1.×2.√3.×4.√5.√6.√7.×8.×9.×10、√二、Translate the following words and phrases into English (20points)1. a bridge(full-wave) rectifier.2.linear device3.timing simulation4.Alternating current circuits5.the combinatory logic electric circuit,三、Translate the following paragraphs into Chinese(40points)一个同步的计数器内部电路结构比较复杂，以保证所有的计数器输出都在每一个时钟脉冲输入时同时改变，同步的计数器可以避免异步计数器中可能出现的误计数。
