The correct answer is: B. A decision table is directly understood by the computer.
A decision table is a tabular representation of logical conditions and their corresponding actions. It is a tool that can be used to describe complex decision-making processes. Decision tables are easy to understand and modify, and they can be used to generate code that can be directly executed by a computer.
However, decision tables are not directly understood by the computer. The computer needs to be programmed to understand the structure of a decision table and how to interpret the conditions and actions. This can be a complex task, and it is often easier to use a different tool, such as a rule engine, to implement a decision-making process.
Here is a brief explanation of each option:
- A. A decision table is easy to modify. This is true. Decision tables are easy to modify because they are a tabular representation of a decision-making process. The conditions and actions can be easily added, removed, or modified.
- B. A decision table is directly understood by the computer. This is false. The computer needs to be programmed to understand the structure of a decision table and how to interpret the conditions and actions. This can be a complex task, and it is often easier to use a different tool, such as a rule engine, to implement a decision-making process.
- C. A decision table is easy to understand. This is true. Decision tables are easy to understand because they are a tabular representation of a decision-making process. The conditions and actions are clearly laid out, and the table can be easily scanned to see what the decision-making process is.
- D. All of the above. This is false. Only option A is true.
- E. None of the above. This is false. Option A is true.
