5、ge assembly language written machine language notation A programming language, designed to facilitate the communication between human and computers, is a _ for describing computation in readable form. There are 3 levels of programming languages, they are _, which can be run directly by computer; _an
6、d_. There are different high-level programming languages. Fortunately, most of them have many kinds of construct in common and vary only in the way that these must be_ . Therefore, first thing to be decided about a task is to choose which programming language is best suited for the job. Passage A Th
7、e central processing unit (CUP) is the heart of the computer systems. Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activ
8、ities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, which its speed and capacity have increased tremendously. Indeed, these changes have resulted in micro-Computers that are small enough to f
9、it on your desk and your lap. The CPU comprise the control unit and the arithmetic/logic unit (ALU). The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic u
10、nit, as well as the control signals between the CPU and input/output devices. The ALU performs all the arithmetic and logical(comparison) functionsthat is, it adds, subtracts, multiplies, divides, and does comparison. These comparisons, which are basically “less than”, “greater than”, and “equal to”
11、, can be combined into several common expressions, such as “greater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next. (二) Tell whether the following statements are true(T) or false(F) according to the passage A(根据上文的

14、d as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C+ was the language of choice. But over time the difficul
15、ties encountered with C+ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design an architecture decisions drew from a variety of language such as Eiffel, SmallTalk, Objective, C, and Cedar/Mesa. The result is a language platform that has pr

CD-ROM Introduced in 1980, the extraordinarily successful CD, or compact disk, is an optical laser disk designed to enhance the recorded reproduction of music. To make a CD recording, the analog sounds of music are translated into their digital equivalents and stored on a 4.72-inch optical laser disk. Seventy-four minutes of music can be recorded on each disk in digital format by 2 billion digital bits. With its treme
