以下关于多任务处理的说法中正确的是()

默认建立的目录开启了超链接功能。只需要按下Shift键，同时在目录上单击鼠标左键，就可以跳转到目录对应的文档位置

应用“引用”选项卡中的【目录】/【插入目录】命令，可以快速自动地为各种形式的文档生成目录

当章、节标题发生变化时，按F9功能键可以自动更新生成的目录

如果要更改目录样式，需要在文档模板中一并进行更改设置

作者是最主要的著作权人

作者是凭借自己的创作而取得著作权的个人

作者以外的其他人不可能成为著作权员

著作权人就是作者

我国境内设立企业的记账本位币可以不是人民币

会计核算只能以人民币作为记账本位币

业务收支以人民币以外的货币为主的单位，可以选择其中一种外币编制财务会计报告

境外单位向境内编报的财务会计报告无需折算为人民币

Think you can walk, drive, take phone, calls, e-mail and listen to music at the same time Well, New York’s new law says you can’t (46) The law went into force last month, following research and a shocking number of accidents that involved people using electronic gadgets(小巧机械)when crossing the street.

Who’s to blame (47) "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist(神经科学家)in Tennessee. "But a core limitation is the inability to concentrate on two things at once."

The young people are often considered the great multitaskers. (48) A group of 18- to 21-year-olds and a group of 35-to 39-year-olds were given 90 seconds to translate images into numbers, using a simple code. (49) But when both groups were interrupted by a Phone call or an instant message, the older group matched the younger group in speed and accuracy.

It is difficult to measure the productivity lost by multitaskers. But it is probably a lot. Jonathan Spira, chief analyst at Basex, a business-research firm, estimates the cost of interruptions to the American economy at nearly ＄ 650 billion a year. (50) The surveys conclude that 28 percent of the workers’ time was spent on interruptions and recovery time before they returned to their main tasks.

使用插码分析技术，需要向页面中嵌入一段监测代码，以实现数据的监测和收集

不同插码分析工具的监测代码可以互相通用

插码分析工具监测代码都是JS代码，所以在不支持JS的平台上无法使用插码分析技术

只要在某个网站的首页加入监测代码，插码分析工具就能够对该网站的数据进行收集和分析了

一般情况下，插码分析技术不适合用于监测服务器状态（比如服务器运行出错等）信息

文件I/O为应用程序提供所需的内存空间

文件I/O通过VFAT虚拟文件表寻找磁盘文件

文件I/O通过限制地址空间避免冲突

设备I/O负责与键盘、鼠标、串口、打印机对话

用户如果只启动一个应用程序，则该程序就可以自始至终独占CPU资源

由于CPU中有多个执行部件，可同时执行多条指令，所以才能同时执行多个任务的处理

从微观上看，前台任务和后台任务能同时得到CPU响应

Windows操作系统在执行32位应用程序时，采用的是按时间片轮转的调度方法
