Software engineering refers to the use of systems engineering principles in the creation of software products and applications. It is a discipline of engineering concerned with assessing user requirements, software design, development, testing, and maintenance.The following are some fundamental principles of excellent software engineering −Better Requirement Analysis is a fundamental software engineering technique that provides a comprehensive picture of the project. Finally, a thorough grasp of user requirements adds value to consumers by producing a high-quality software solution that satisfies their needs.All designs and implementations should be as basic as feasible, which implies adhering to the KISS (Keep it Simple, ...

What is Automation Testing and How Does It Work?Automation Testing, often known as Test Automation, is a software testing approach that involves the execution of a test case collection using particular automated testing software tools. On the other hand, manual testing is carried out by a person sitting in front of a computer, methodically carrying out the test processes.In addition to entering test data into the System Under Test, the automated testing software may analyze predicted and actual outcomes and provide complete test reports. Software Test Automation necessitates significant financial and human resources.Continuous implementation of the same test suite will ... Read More
What exactly is application testing?Application testing is a sort of software testing that is carried out using codes with the goal of detecting faults in software. It is concerned with testing the complete application.It aids in improving the performance of your products as well as lowering expenses, increasing ROI, and shortening production time.Application testing may be conducted in several areas such as GUI, functionality, database (backend), load test, and so on.The testing phases for application testing comprise stages such as requirement analysis, test strategy, test analysis, test plan, test execution, and issue management, among others.You will learn the following in ...

What is an API?An API (Application Programming Interface) is a computer interface that allows two different software systems to communicate and share data. A software system that performs an API has numerous functions/subroutines that may be performed by another software system. Between two software systems, an API describes the types of requests that can be made, how they may be made, the data formats that can be utilized, and so on.Shift Left TestingShift Left Testing is one of the most common forms of testing that is now being asked in API Testing Interviews. Almost every project that follows the Agile ... Read More
What is Agile Methodology?The term "agile methodology" refers to a process that encourages continuous development and testing throughout the project's software development life cycle. Unlike the Waterfall paradigm, both development and testing operations are contemporaneous under the Agile style of software testing.Agile Methodology Vs. Traditional Software DevelopmentOne of the easiest and most successful ways to transform a vision for a company requirement into software solutions is to use the Agile software development approach. Continuous planning, learning, improvement, team collaboration, evolutionary development, and early delivery are all terms used to define agile software development methodologies. It increases adaptability in the face ... Read More
Accessibility testing is a sort of software testing that ensures that the application under assessment is useable by individuals with impairments such as hearing loss, color blindness, old age, and other disadvantaged people. Usability Testing is a part of it.People with impairments utilize assistive technology to help them operate software. Here are some examples of such software −Speech Recognition Software - It converts spoken words to text, which is then used as input by the computer.Screen reader software - This program is used to read aloud the text that is shown on the screen.Screen Magnification Software - This software is ...

Given a linked list, we need to remove its first element and return the pointer to the head of the new list.Input : 1 -> 2 -> 3 -> 4 -> 5 -> NULL Output : 2 -> 3 -> 4 -> 5 -> NULL Input : 2 -> 4 -> 6 -> 8 -> 33 -> 67 -> NULL Output : 4 -> 6 -> 8 -> 33 -> 67 -> NULLIn the given problem, we need to remove the first node of the list and move our head to the second element and return the head.Approach to ...

In this article, we will explain the way to remove every k-th node of the linked list. We must delete every node that sits on the multiple of k, i.e., we have to delete the node on positions k, 2*k, 3*k, etc.Input : 112->231->31->41->54->63->71->85 k = 3 Output : 112->231->41->54->71->85 Explanation: As 3 is the k-th node after its deletion list would be : First iteration :112->231->41->54->63->71->85 Now we count from 41 the next kth node is 63 After the second iteration our list will become : 112->231->41->54->71->85 And our iteration continues like this. Input: 14->21->23->54->56->61 k ... Read More
Locality of reference refers to the tendency of the computer program to access the same set of memory locations for a particular time period. The property of Locality of Reference is mainly shown by loops and subroutine calls in a program.On an abstract level there are two types of localities which are as follows −Temporal localitySpatial localityTemporal localityThis type of optimization includes bringing in the frequently accessed memory references to a nearby memory location for a short duration of time so that the future accesses are much faster.For example, if in an instruction set we have a variable declared that ...

Instruction cycle consists of fetch, execute and interrupt stage show in below diagram −If any interrupt occurs, it is indicated by an interrupt flag. The CPU will go to interrupt handler routine. Interrupt handler then checks the type of interrupt and executes the appropriate function. It involves overhead but still better than the CPU waiting for I/O completion or other activities.Interrupt handler activates most prior able activity first and later deferrable part will be handled.ExampleBlock of data arrives on the network line.Kernel marks the presence of data (urgent part) and gives the CPU back to the process that was running ...
