Software Engineering: Question Set – 27

What is the difference between computer engineering (CE), computer science (CS), and software engineering (SE)?

  • Although courses in software are typically covered in computer engineering degree programmes, a much greater emphasis is placed on the software development process and practice in software engineering degree programmes. These practises and processes include more advanced aspects of software architecture, requirements management, quality assurance, and process improvement. In contrast to computer engineering degrees, software engineering programmes put less emphasis on the physical components of computers and electronics.
  • On the other hand, computer science serves as the foundation for software engineering, much like how other branches of engineering are founded on either the natural or living sciences. Software engineering, on the other hand, places a greater emphasis on concerns relating to methodology, design, measurement, analysis, and verification. In general, scientists are interested in acquiring new knowledge, whereas engineers wish to create things, find solutions to problems, and assist others. Both responsibilities are essential to the whole.

Why are software engineers needed?

Computer systems are everywhere and have a significant influence on society as a whole. All computer systems, including the so-called “embedded systems” that are utilised in communication networks, cars, consumer electronics, and medical equipment, contain software as an essential component. Software engineers are equipped with the knowledge and abilities necessary to develop the kind of high-quality, efficient software that is essential to the operation of all of these computer systems.

Mention some challenges of software development.

  • This is a very significant interview question that focuses on software engineering, and it’s asked rather frequently. The following are some of the issues that are faced during software development:
  • Because technology is advancing at such a fantastic rate, software developers are under increasing amounts of pressure to continuously educate themselves and modify their practises in order to remain competitive in their fields.
  • a rise in the expectations of customers Each individual customer has their own unique requirements. In order to comprehend the customer’s software needs, software developers need to have a working knowledge of business concepts.
  • Constraints imposed by time: the work of software developers is required to adhere to stringent time deadlines. The difficulty is made even more difficult for remote software developers because they work across multiple time zones. The productivity of software engineers might suffer when they are constrained by time, which can result in products of substandard software quality.
  • There is a shortage of resources at many software development organisations, including high-performing software development tools, powerful computer platforms, ineffective data storage, and inefficient network capabilities. All of these things can have a negative impact on the software development team’s overall efficiency and performance.
  • Conflicts with the teams responsible for testing software Software development teams and the teams responsible for testing software frequently find themselves at odds with one another. The opposing nature of development and testing, as well as the significant amount of pressure associated with both work and performance, are major contributors to this phenomenon.
  • Managing legacy systems: A significant number of companies continue to operate with older legacy systems, despite the fact that doing so might increase the likelihood of security breaches, decreased productivity, and incompatibility with newer technologies. As a result, there is an urgent requirement for the upgrading of legacy software.
  • The issue posed by heterogeneity is that, given the ever-shifting nature of client requirements, one of the most difficult aspects of developing software is ensuring that it is both adaptable and reliable so that it can meet current and future requirements.

Please describe the various kinds of static testing tools.

The following categories of static testing tools are available:

  • code-based: These testing tools use the source code as their input, and then use that information to construct test cases based on the code.
  • Specialized: The language is utilised within these testing tools in order to write comprehensive test specifications for each and every test case.
  • The test cases that are generated by these testing tools are designed depending on the requirements provided by the user.
  • Remember to use examples from your own experience when responding to questions like this one during the interview to become a software engineer.

Talk about equivalence partitioning.

  • A technique for testing software known as equivalence partitioning divides the input data of a software unit into partitions that each contain data that is equivalent to the other partitions.
  • The test cases, which in principle should cover each partition at least once, can be more easily derived with the help of these partitions.
  • The number of test cases that need to be produced can be cut down as a result of partitioning, which enables the test cases to identify categories of faults. When there are fewer test cases to run, the amount of time necessary to test software gets cut down as well.
  • Even though this method is typically applied to the inputs of a tested component, there are a few exceptional circumstances in which it could be applied to the outputs as well.

Talk about how you ensure quality and fix bugs.

  • The focus of this type of software engineering interview question is on the candidate and the procedures that they use to assure quality in their work.
  • You must have a strong grasp of quality control if you want to advance to the role of senior developer. In addition to this, you need to have a method for tracking down software errors and rectifying them.
  • Testing that is code-based, for instance, can be used to locate potential problems in software. You may ask someone else on your team to perform a peer review of the code that you have written for the product that you are testing.
  • They might discover a flaw in the logic that causes the output to be erroneous. You are able to fix the code, and after that, you can utilise dynamic testing to determine whether or not the functionality of the software is satisfactory. It is my sincere hope that it will.

Differentiate between alpha and beta testing.

These are the two primary categories of acceptance testing.

  • Alpha test: Alpha tests are tests in which the client evaluates a full version of the programme while the developer observes and provides feedback. The location of this kind of testing is at the developer’s location.
  • Beta test: Beta testing are tests in which the client evaluates a version of the programme independently from the supervision of the software developer. This form of testing is carried out at the location of the customer.

Mention the different types of software maintenance.

The following is an overview of the various types of software maintenance:

  • Corrective: The purpose of corrective maintenance is to correct any errors that may have been introduced into the software.
  • Adaptive: The programme is better able to adjust to changes in its environment when adaptive maintenance is performed on it.
  • Perfective: Maintenance that focuses on perfection assists in modifying or enhancing a system so that it can conform to newly established standards.
  • Preventive: Alterations are performed to improve the system’s future maintainability as part of preventive maintenance, sometimes known as “preventive maintenance.”
