What are the defects of the application software? Causes of software defects

There is some software that is distributed without adequate testing**, and running such buggy software can cause the system to freeze or not boot properly. In this case, you should find the latest version of the software or simply uninstall it.

Unclear requirements: Unclear software requirements or developers' unclear understanding of requirements lead to software design that deviates from the customer's requirements and goals, resulting in defects in software functions or features. In addition, frequent changes in customer requirements during the development process can also affect the final quality of the software.

Complex software structure: If the software system structure is complex, it is difficult to design a framework with a good hierarchy or component structure, which will lead to difficulties in software development, expansion, and system maintenance. Even if a good architecture can be designed, complex systems can be implemented with hidden interacting challenges, leading to hidden software flaws.

Coding issues: In the software development process, the level of programmers is uneven, coupled with the lack of effective communication and supervision during the development process, problems accumulate and accumulate and if they are not solved one by one, it will lead to many defects in the final software.

Short project period: Most software product development cycles are very short, and the development team has to complete the development of software products in a limited time, which is very stressful, so developers are often in a state of fatigue, pressure, and interference to develop software, and in such a state, the developer's attitude towards software problems is "not serious, not solved".

Use of new technologies: In modern society, every technological development is changing with each passing day. When using new technologies for software development, if the new technology itself is insufficient or the developers do not have a good grasp of the new technology, it will also affect the development process of the software product and lead to defects in the software.

The actual requirements of the software itself are not clear, resulting in the objectives involved deviating from the actual requirements2The system structure is so complex that it is not possible to cover a good hierarchy or structure, which leads to unexpected problems or difficulties in system maintenance and expansion Because there are so many types of objects, it is difficult to complete a variety of objects. Class interactions compose tests while hiding some issues such as number passing methods, calling objects, state changes, etc.

The causes of software defects include the following:

1. Man-made design defects: defects caused by the designer's negligence, insufficient technology or overly complex design.

2. Coding errors: Defects caused by spelling errors, grammatical errors, capitalization errors, data type errors, etc. when the programmer writes the source **.

3. Refactoring problem: the defects caused by reuse and improvement of software refactoring.

4. The software fails to meet the requirements: the software designers or testers do not fully understand the user needs or technical details, resulting in the defects that the software fails or does not meet the needs of the users.

6. Regulations and standard problems: software designers or programmers fail to code in accordance with specifications such as coding, document writing, and naming style, resulting in defects.

7. Hardware failure: Hardware failure can lead to defects, such as IO device failure, memory disk failure, etc.

8. Environment and configuration errors: When the functions of the software and the associated configuration are not completely correctly matched, it may lead to defects. For example, applications require higher memory or processor speed to function properly.

Therefore, developing the right test plan and accurately identifying the cause of defects is a crucial step in software development to help developers fix defects and go live in a timely manner.

For software defects, there are usually the following handling processes:

2. Defect classification: classify the defects found, determine their priority and scope of influence, so as to facilitate subsequent processing.

3. Defect analysis: Conduct defect analysis to find out the root causes and influencing factors of defects.

4. Defect repair: According to the analysis results, the defect is repaired, including modification, retesting, etc.

5. Defect verification: verify the repaired defects to ensure that the defects have been completely repaired.

6. Defect closing: After the defect verification is passed, the defect is closed, and the defect processing information and repair situation are recorded.

7. Defect analysis summary: summarize the defect analysis results, find out the common defect causes and solutions, and further improve the software quality and efficiency. Clan void.

Summary. Dear, I'm glad to answer for you, there are 3 types of software defects to identify. 1.

Potential defects in the work. A latent defect is a hidden defect in the software that cannot be identified by the user until the end of a set of operations (although the developer or owner knows about it). 2.

Hidden defects. A hidden defect is a defect that is already present in the software, however, it has not yet caused the failure of the application execution, mainly because it is covered or masked by another defect. 3.

Cascade of defects. In software testing, defect cascading means triggering other defects in an application. <>

There are several types of software defects that can be identified.

What are they.

Dear, I'm glad to answer for you, there are 3 kinds of software defects. 1.Potential defects in the work.

A latent defect is a hidden defect in the software that cannot be identified by the user until the end of a set of calculations (although the developer or owner knows that it is noisy). 2.Hidden defects.

A hidden defect is a defect that is already present in the software, however, it has not yet caused the failure of the grip of the application execution, mainly because it is covered or masked by another defect. 3.Cascade of defects.

In software testing, defect cascading means triggering other defects in an application. <>

Latent defects in work, hidden defects, cascading defects.

Just 3? Yes.

Oh oh good thank you.

Extended information: The significance of biometric recognition: intelligent machines can obtain and analyze the physiological and behavioral characteristics of the human body to realize automatic identity identification Who are you, state analysis of posture, expression, attribute estimation of gender, age, and ethnicity Science and technology.

Common biometric extraction: fingerprint, iris, face, palm print, hand shape, human ear, retina, DNA, vein finger vein, palm source late vein, handwriting, gait and voiceprint and other biometrics is a complex interdisciplinary discipline, including optics, mechatronic engineering, algorithm pattern recognition, machine learning, computer vision, artificial intelligence, digital image processing, signal analysis, cognitive science, neural computing, human-computer interaction and information security. Iris recognition also faces some challenges, especially in the field of uncontrolled complex scenes, user non-cooperative repentance scenes, and medium and long-distance iris recognition.

Iris recognition research is also gradually changing from "high cooperation and strict screening" (requiring high user cooperation and strict screening of image quality) to "low cooperation and high throughput" (low user cooperation and high throughput recognition). <>

a.The software does not meet the target that is not specified in the product manual.

b.The software requirements are divided into circles, and the documentation is not perfect. Tangerine sleepy.

c.The software has an error that the product manual indicates will not occur.

d.Software functionality is beyond the scope of the product manual.

Correct answer: B
