Answer: a An Algorithm Explanation: An algorithm is a precise step-by-step technique that takes an input instance of the given problem as input s and produces output for the problem instance. Answer: a Quality Explanation: The quality of a functional software functional depicts how well it can conform with or adapts to a given design based on functional requirements or specifications.
Answer: c All the functions represented in the DFD are mapped to a module structure Explanation: The module structure depicts the architecture of the software.
Answer: a Data Flow Explanation: In the business information system, the data flow diagram is used to epitomize the flow of the data. Answer: d All of the above Explanation: A logical file can be a data structure or physical file on the disk or vice versa. Answer: c Efficiency Explanation: Efficiency can never be measured as it is an indirect measure of the SE process.
Answer: a To evaluate the ongoing project's status and track possible risks. Answer: d To minimize the development schedule and evaluate the ongoing project's quality on a daily basis Explanation: A project metric refers to a quantifiable measure of the degree to which a system, component, or process owns a certain trait.
Answer: c Control Chart Explanation: A control chart is a method used to keep track of the variability of traits of interest. Answer: d All of the above Explanation: Estimation cost works out on assessing the amount of effort required to complete each activity, followed by calculating the total cost of activities.
Answer: c Internship management Explanation: Configuration management policies and processes define how to record, and process proposed system changes, how to decide what system components to change, how to manage different versions of the system and its components, and how to distribute changes to customers.
Answer: b Decomposition Explanation: None. Answer: a The ability to translate the size estimate into human effort, calendar time, and dollars Explanation: None. Answer: a Empirical estimation models Explanation: In computer software, the estimation model uses empirically derived formulas for guessing the effort as a function of LOC or FP.
Answer: a Costs of lunch time food Explanation: Employees incur it in the office. Answer: c Algorithmic cost modeling Explanation: The algorithmic cost modeling utilizes the basic regression formula with such parameters that have been derived from the data of a historical project and current as well as characteristics of a future project. Answer: c An application-composition model Explanation: An application-composition model evaluates the development of a prototype.
Answer: a Application composition model Explanation: None. Answer: c Technical risks Explanation: Technical risks detect the possible design, enactment, interface, authentication, and preservation problems. Answer: c Risk projection Explanation: Once the risks are identified, the project manager takes his first step to avoid them when required and control them. Next Topic. Reinforcement Learning.

System Design Coding System Testing Preliminary Investigation and Analysis Show Answer Workspace Answer: d Preliminary Investigation and Analysis Explanation: The first phase of the software development life cycle is the requirement analysis, in which the software engineer analyzes the software requirement based on the user's outlook.
It necessitates customer feedbacks. It increases the component reusability. Higher amount of risk analysis Doesn't work well for smaller projects Additional functionalities are added later on Strong approval and documentation control Show Answer Workspace Answer: b Doesn't work well for smaller projects Explanation: A spiral model is an incremental approach, which is formed as a combination of the waterfall model and prototyping model.
The prototyping model facilitates the reusability of components. Design strategy II. Transformation into product III. Implementation IV. Requirement gathering 4, 1, 3, 2 4, 3, 2, 1 1, 2, 3, 4 1, 4, 2, 3 Show Answer Workspace Answer: a 4, 1, 3, 2 Explanation: The sequence of activities mentioned in option c represents the Fourth Generation Techniques 4GT Model.
True False Show Answer Workspace Answer: b False Explanation: The fourth-generation programming languages are more programmer-friendly and helpful in augmenting the program's efficiency as it uses English words and phrases. The productivity of software engineers is improved. The time required for developing software is reduced.
CASE tools and code generators help the 4GT model by providing a credible solution to their problems. Service-Based Architecture and Microservices Service-Based Architecture and Microservices are some of the most critical best practices in software engineering today.
Service-based architecture is a software design best practice where services are provided to other components by application components, through communication protocols. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently. It has four properties:. Software Modelling Using visual modeling tools helps to improve the ability to manage software, rationalize, and maintain that software.
It will also help to keep information among the team easy to understand and constant — which is especially important in agile development when multiple teams are working laterally to develop the same software or updating the same application portfolio. Software Testing Software Testing is another critical element of software engineering best practices and principles. A team wants to verify that all software developed is high quality and meets the requirements set forward in the planning stage.
Remember that changing software later in development is much, much costlier. Continuous testing from the start of development will help to avoid costly repairs later on or even after deployment. Software engineering practices that do not include testing will eventually fail — but not after costing a lot of time and money from your budget. Software engineering theory and practice meld together computer science with artistry and design. Abstraction is a theory in both art and software engineering.
Abstraction is the simplification of a description into the bare-bones essentials. In software engineering theory, this means making code easy enough to read and edit. Elements have to be well named so that they are descriptive — typically only using a combination of verbs and nouns.
The software engineering process is one that is complicated, but with discipline, education and guidance it can become predictable. You will likely have the same steps with each product, though the time you spend on each level will vary depending on your goals and team.
A software engineering process is the model chosen for managing the creation of software from initial customer inception to the release of the finished product.
Several software engineering process models exist and vary mainly in the frequency, application and implementation of the above techniques, for example, different process models use different analysis techniques, other models attempt to implement the solution to a problem in one big-bang approach, while others adopt an iterative approach whereby successively larger and more complete versions of the software are built with each iteration of the process model.
There are many fundamentals of software engineering — so many that some will get lost over time. They are in place so that when you need to make changes somewhere down the line, you will have a team that understands everything and can focus on them. Still, it is essential to know that finding and fixing a software problem after it has already been deployed is much, much more expensive than it would be to find it during the design phase. Using a tool to find those bugs and fix them early can be a budget saver.
Why is this so effective? Because at least half of the errors in a finished product were committed early on in the design stage.
