    The architecture design specifies the overall architecture and the placement of software and hardware that will be used. Architecture design is a very complex process that is often left to experienced architecture designers and consultants. The first step is to refine the () into more detailed requirements that are then employed to help select the architecture to be used and the software components to be placed on each device. In a (), one also has to decide whether to use a two-tier, three-tier, or n-tier architecture. Then the requirements and the architecturedesign are used to develop the hardware and software specification. There are four primary types of nonfunctional requirements that can be important in designing the architecture. () specify the operating environment(s) in which the system must perform and how those may change over time. ( 请作答此空) focus on the nonfunctional requirements issues such as response time, capacity, and reliability. () are the abilities to protect the information system from disruption and data loss, whether caused by an intentional act. Cultural and political requirements are specific to the countries in which the system will be used.

    【录音原文】
    　　M: Our guest today is Alas Baker who has a very unusual ability. Alas, thank you for coming into the studio. What kind of unusual ability are we talking about here?
    　　W: Wow, it’s quite easy to describe. Basically, when I read a word or even think of a particular word, such as Tuesday, I see a color connected with it. It’s not that I imagine a color. I really see it loading in front of my eyes.
    　　M: How interesting! Is it a sort of medical condition?
    　　W: Yes. And just recently doctors have begun to understand it more. They call it synesthesia, which means that somewhere in my brain, there are links between sections that should really be separate. Other people have a form of this condition that affects emotions. So they see colors when they feel particular emotions. Apparently, it’s generally passed on from parents to their children, which is the case with me.
    　　M: Do you have any brothers or sisters with the same ability?
    　　W: Yes, my brother is the same as me. If we start talking about it, people think we are completely mad. When we were younger, we used to have arguments about things like what color the word Tuesdayis. It turns out that everyone with this condition sees different colors.
    　　M: It sounds as though it could make life quite exhausting.
    　　W: I suppose it does. But you see, if you’ve never known anything different, you don’t think of it like that. It does make you aware of your moods. I know when I started to feel depressed, things begin to look grey.
    　　M: Are there any other advantages do you find?
    　　W: Well, it seems that quite a lot of artists and musicians have this condition. So I guess it can be beneficial if it’s combined with some sort of gift or natural talent, which is not the case with me unfortunately. But I do find that it makes reading very interesting, because sometimes a sentence has a very nice range of colors. So you want to read it again just to experience that. Of course, this makes me quite a slow reader.
