《计算机组成及汇编语言原理》阅读笔记：p200-p240

《计算机组成及汇编语言原理》学习第 15 天，p200-p240 总结，总计 40 页。

一、技术总结

1.derived type

(1)定义

A representation for data built up by combining basic types. For example, a fraction type could be derived from two integers, the numerator and the denominator.

(2)示例

这里以 Java 语言为例，array 是一种 derived type。p201, One of the simplest and most common kinds of derived types is the array. From a theoretical and platform-independent perspective, an array is a collection of elements of identical type indexed by an integer.

二、英语总结(生词：3)

1.envision

(1)envision: en-("make, put in") + vision("something seen in the imagination")

vt. to image sth to happen/to expect sth to happen (设想，期望)。

p204, However, the ability to support typed computations even when the types involved are user-defined is critical to the cross-platform security envisioned by the designers of the JVM.

2.coherent

(1)coherent: co-("together, with") + haerere("to adhere, stick")

adj. coherent originally referred to things that are connected or sticking together, and it now describes ideas or elements that are logically connected(有条理的，连贯的).

p210, In order to structure these objects into a coherent framework, they are usually grouped into (and written as) classes of similarly propertied objects.

3.taxonomy

(1)taxonomy: taxis("arrangement") + -nomy("method")

c/u. science of classification(分类学)。

三、其它

chapter 10 简评：介绍 JVM 上的编程：派生类型，类、对象、继承、class 文件。

完结，撒花。
