问题 单项选择题

Windows系统中内置了一些用户组,其中,对计算机拥有不受限制的完全访问权的用户组是(1);权限最低的用户组是(2)。 空白(2)处应选择()

A.Administrators

B.PowerUsers

C.Users

D.Guests

答案

参考答案:D

解析:

本题考查Windows系统管理方面用户组的基础知识。

Windows系统中有Users、PowerUsers、Administrators、Guests等用户组。

Users(普通用户组)是最安全的组,因为分配给该组的默认权限不允许成员修改操作系统的设置或用户资料。

Users组有最安全的程序运行环境。

PowerUsers(高级用户组)可以执行除了为Administrators组保留的任务外的其他任何操作系统任务。

分配给PowerUsers组的默认权限允许PowerUsers组的成员修改整个计算机的设置。但PowerUsers不具有将自己添加到Administrators组的权限。

在权限设置中,这个组的权限是仅次于Administrators的。Administrators(管理员组)的用户对计算机/域有不受限制的完全访问权。分配给该组的默认权限允许对整个系统进行完全控制。Guests(访客)是权限最低的用户组,一般用于对本机共享文件的访问。

Among various programs, TV talk shows have covered every inch of space on daytime television. And anyone who watches them regularly knows that each one is different in style(风格). But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey shows.

Jerry Springer could easily be considered the king of “rubbish talk”. The contents on his show are as surprising as can be. For example, the show takes the ever-common talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people’s lives.

Like Jerry Springer, Oprah Winfrey takes TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality(质量) of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.

Compared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a “final word”. He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.

Clean as it is, the Oprah show is not for everyone. The show’s main viewers are middleclass Americans. Most of these people have the time, money, and ability to deal with life’s tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society. These are 18-to-21-year-olds whose main troubles in life include love, relationship, sex, money and drug. They are the ones who see some value and lessons to be learned through the show’s exploitation.
