Answer 92: (A) Systems Thinking : A System is a collection of parts or subsystems integrated to accomplish an overall goal. A system have inputs, outputs, and outcomes, with a feedback process for improvement. If one part of system is removed, the nature of system is changed. Systems range from simple to complex. Like A functioning car is a system, if the carburetor is removed, it will no longer be a working system.
Similarly, an organization is comprised of many departments, development, testing, support, sales etc. By thinking of an organization as a system, it helps managers to diagnose problems, not only by examining what appear to be separate pieces of the organization, but by recognizing larger patterns of interactions, to reach to the final goal.
Answer 93: Application software is a subpart of the Information System. There are various parts of an Information system. Information system is a combination of hardware, software, and telecommunications networks that people build and use to collect, create, and distribute useful data, typically in organizational settings. These components are interrelated to work together to achieve a functionality. These may differ how they are used across different organization.
1. Resources of people: (end users , system analyst, programmers, data administrators etc)
2. Software: (programs and procedures).
3. Hardware: (Physical computer equipments and associate device, machines and media)
4. Data: (data and knowledge bases), and
5. Networks: (communications media and network support).
Answer 94: Let's say you want to make Some Dish. First you go find a recipe for it. Think of the recipe as your methodology. If you follow the methodology, you have a good chance of ending up with a good Dish. If you don't follow the methodology and you have not had prior experience in this, you might just end up with scrap. In project management terms, this would be a failed project.
Now, by following the recipe/methodology, you will no doubt need some tools to accomplish the final goal. You will need a tool capable of producing enough heat to cook with such as a stove or fire. You will also need a pot and cooking utensils. Think of these things as tools that you employ. Without tools, you can't get the job done.
When you follow the recipe/methodology and use your tools, you will come across some techniques. Such as, you can use reduce the hot chili peppers recipe amount by half when preparing Some Dish for those who can't take food too spicy. Think of techniques as suggestions that can be useful to help ensure success of the project.
Methodology is the systematic, theoretical analysis of the methods applied to a field of study.
Tools are the appliances or an abstract used to acheive the functionality.
Technique is concerned with both the skill and ability of doing or achieving something and the manner of its execution.
Answer 97: Decomposition is the process of dividing a complex problem into smaller parts/modules, also know as factoring. Once the smaller subproblems are solved, these can be integrated to achieve the overall functionality.
Answer 98: In Computer Science, Coupling is known as the degree of interdependence between software modules. Coupling is not advantageous because it can affect other modules functionalty if something went wrong with one module, and it is not easy to remove the module and replace with some other option without affecting the overall functionality of the system.
