推理不正确。Flash也可以被改变，但是是non-volatile。取决于是否需要供电。
我觉得不用。但是如果书上说必须，那就必须吧。主要是方便。非要不用内存，也可以
读到任何硬盘的内容。
可以这么说。我觉得没有人会问这个问题。这有点象电影《三个傻瓜》里面那些印度人
，在死记硬背一些根本没有意义的定义，比如，什么是机器。
Java就是portable吧。
也可以解释执行。

发帖数: 3409 | 5 楼主，你不妨先详细谈谈自己对这些概念（以及相关概念）的理解，理解不对的版友可
以给你一一纠正。单纯的True/False回答对你没有助益。不自己尝试而期待别人直接给
解释更是不可取，就算是急着应付面试这也不是应有的态度。 |

发帖数: 3043 | 6 这个建议很中肯。楼主不妨跟大伙说说学编程目的是什么？基础如何？写过多少年多少
行代码？要找什么样的工作？你不一定非得听大家的，但是多了解各方面建议总没错。
