请分析信息系统控制中一般控制和应用控制的区别。

答案

参考答案:答案:
一般控制和应用控制是信息系统控制的两大类别,两者都是用于预防和发现信息系统所发生的错误、舞弊及故障,使之正常运行的特殊控制。
一般控制是指对整个计算机信息系统及环境要素实施的,对系统所有的应用或功能模块具有普遍影响的控制措施。一般控制主要是有关电子数据处理的政策和制度。它叉可被进一步划分为人员或组织控制、逻辑访问控制、设备控制和业务连续性措施等方面。
应用控制是为适应各种数据处理的特殊控制要求,保证数据处理完整、准确地完成而建立的内部控制。应用控制涉及各种类型的业务,每种业务及其数据处理都有其特殊流程的要求,这就决定了具体的应用控制的设计需结合具体的业务。但由于数据处理过程一般都由输入、处理和输出三个阶段构成。所以通常将应用控制进一步划分成输入控制、处理控制 (也称过程控制)和输出控制。应用控制可以弥补一般控制的某些不足。

     Vampires (吸血鬼)

     Vampire stories go back thousands of years. The acts we now associate with vampires, such as rising

from the grave and drinking blood, were popularized by Eastern European stories. 

     Most early cultures created stories to explain things they didn't understand. For example, hair and nails

continue to grow after people die, which has already been proved possible by modern science.

     These facts were unknown to most people in the 19th century, however. As a result, the legends

surrounding such mysteries were kept alive.

     Count Dracula

     In 1897, Irish writer Bram Stoker's novel Dracula was published, spreading the vampire stories to a mass

audience. In the hovel, the Count Dracula of Transylvania, a 500-year-old vampire, has drunk his country

dry and must move to England in search of new victims. Dracula means "son of the dragon" or "son of the

devil" in Romania.

     Werewolf

     The story of a half-man, half-wolf beast is as old as that of vampires, and almost as varied. In most

werewolf stories, however, a beast would silently enter settlements at night and steal a young child or an

animal.

     The most common explanation of werewolf stories is that the beast was usually an ordinary wolf. The

genetic disorder, which causes too much body hair, may also have helped to popularize the story.

     Frankenstein

     This is a fictional scientist created by British writer Mary Shelly in 1818. Dr. Frankenstein lives m a castle

and is so addicted to making living beings from parts of dead bodies that he refuses to marry.

     The story of Frankenstein may have been planted in Shelly's mind since she visited Castle Frankenstein in

Germany, where an alchemist (炼术士) tried to do experiments with the aim of making people live longer.

     The Invisible Man

     In H.G.Wells' 1897 story, a young scientist called Griffin, manages to make himself invisible. But he

cannot find a way to become visible again. He then wants to make use of his super power but finally has

gone mad. Wells' tale owes a great debt to Greek philosopher Plato's book Republic.
