问题 单项选择题

操作系统的一个重要功能是进程管理。为此,操作系统必须提供一种启动进程的机制。在下面的叙述中,不正确的是______。

A.在DOS中,该机制是EXEC函数

B.在Windows中启动进程的函数是CreateProcess

C.在OS/2中启动进程的函数是CreateProcess

D.在DOS中启动进程的函数也是CreateProcess

答案

参考答案:D

解析:[知识点] 操作系统的基本功能
[评析] 操作系统必须提供一种启动进程的机制。在DOS中,该机制就是EXEC函数。在Windows和OS/2中启动进程的函数是CreateProcess,它的代码存储在操作系统的内核里,在KERNEL32.DLL文件中。当 CreateProcess接受—个可执行的文件名后,它便可装入该文件并开始执行。但与EXEC不同的是CreateProcess在调用后几乎能立即返回,以便更多的程序可以启动。因为Windows和OS/2是多任务操作系统,它们允许多个程序同时运行。

Subject: Customer Complaint

To Whom it May Concern,

I have trusted the Shoe People to protect the feet of my employees for over ten years now. I recently purchased a few pairs of boots from your company for my crew. Though my men were initially satisfied with the boots, the soles began to fall apart on them after just twelve weeks. This was extremely surprising considering they came with a six year warranty. The boots are unsafe to wear because my men are pouring hot concrete. Please respond as soon as possible with instructions on how I can return the boots and receive a refund.

Thank you,

John Trimbald, Foreman, JT Construction

Dear Mr. Trimbald,

Thank you for your e-mail concerning the poor quality of our rubber soled black workboots. A representative will be by your office next week to pick up the damaged boots. We apologize for any inconvenience this has caused you and your crew.

Along with five new pairs of workboots for your crew (we included one extra pair), we have enclosed a free year's supply of sole protector spray. In our retail stores, this spray is always recommended to buyers who work on heated floors. This should have been brought to your attention at the time of your initial order. Please excuse our oversight.

To date we have had no complaints about these workboots from customers who have used the protector spray. However, should you use the spray and find that you are still unsatisfied with the boots, please return the boots and spray for a full refund. Thank you for supporting The Shoe People. Have a Happy New Year.

Sincerely,

Stan Mason, President
