The severity of the BugThe severity of the bug or the defect A problem or a Defect's severity in testing refers to how much of an impact it has on the software program under test. A higher severity rating indicates that the bug/defect has a greater impact on system functionality. The severity level of a bug or defect is generally determined by a Quality Assurance engineer.What is the meaning of priority?The order in which a fault should be repaired is referred to as a priority. The higher the priority, the faster the problem should be fixed.Flaws that render the software ... Read More
The Security System Development Life Cycle (SecSDLC) is a series of activities that are carried out in a certain order throughout the software development process (SDLC). It is created in such a manner that it can assist developers in creating software and apps in such a way that security risks are reduced greatly from the start.The Security System Development Life Cycle (SecSDLC) is similar to the Software Development Life Cycle (SDLC), but the activities carried out in each step of the cycle are different. SecSDLC is a process that includes identifying specific threats and the risks that such threats pose ... Read More
Manual TestingManual testing is a sort of software testing wherein test cases are personally run by a tester instead of utilizing automated technologies. The goal of manual testing is to find errors, faults, and flaws in a software product. Manual software testing is by far the most basic of all testing methods, and it aids in the discovery of serious problems in software applications.Even before new app can be automated, it must first be manually evaluated. Manual software testing takes more time and effort, but this is required to determine if automation is possible. Manual testing principles do not need ... Read More
There is an agreed-upon manner of doing things whenever we start a company, whether online or in the conventional sense. This is referred to as "Standards." For example, if you want to start a company creating bed linens, the minimum length of bedsheets required by industry standards is 7 feet. These guidelines might be publicly published or followed in an unwritten manner.What is the Purpose of Standards?As consumers, standards assist us in determining whether or not something is appropriate for the purpose for which it is purchased, and whether or not it is of acceptable quality. It's also easy to ... Read More
The V-Model is a highly rigorous SDLC model in which each development phase is followed by a testing phase. The V model is a variation of the waterfall model, in which testing is carried out in tandem with development at each stageSoftware Engineering TerminologySoftware Development Life Cycle (SDLC) − SDLC stands for Software Development Life Cycle. Developers do a series of tasks in order to create and construct high-quality software.The Software Testing Life Cycle (STLC) − is an acronym for Software Testing Life Cycle. It is a set of tasks carried out methodically by testers to test your software product.Waterfall ... Read More
What is Integration Testing?Integration Testing is a sort of testing in which software modules are conceptually connected and tested as a unit. A typical software project is made up of several software modules written by several programmers. The goal of this level of testing is to find flaws in the way various software components interact when they're combined.Integration testing is concerned with ensuring that data is communicated between various units. As a result, it's also known as "I & T" (Integration and Testing), "String Testing, " and "Thread Testing."What is Integration Testing and How Does It Work?What is the purpose ... Read More
Let us understand what a process state is.Process StatesProcess states are the states in which the process is currently residing. There are basically five states of processes −New − The process is about to be created in this state but not yet created. It is the program which is present in secondary memory that will be picked up by OS to create the process.Ready − The process enters the ready state after the creation of a process that means the process is loaded into the main memory.Running − The process is chosen by the CPU for instructions and the executions ...

Threads that are available at user level are called as user threads. Threads available at kernel level are called kernel threads. User threads are supported above the kernel and are managed without kernel support and kernel threads are supported and managed directly by the operating system.Types of multithreading modelsThe different types of multithreading models are as follows −Many-to-one modelIt maps many user threads to one kernel thread. The thread management is based on the thread library in user space, because of this it is efficient but the entire process is going to block if a thread makes a blocking system ... Read More
Process scheduler assigns different processes to CPU based on particular scheduling algorithms.The scheduling is responsible for taking part in the scheduling process that is the set of the policies and mechanisms to control the order in which the jobs can be completed. By using the scheduling algorithms the scheduler is done.Types of Process Scheduling AlgorithmsThe different types of process scheduling algorithms are as follows −FCFS(First Come First Serve)SJF or shortest job next.Round Robin.Shortest Remaining time.Priority Scheduling.Multiple level queues.The scheduling criterion is responsible for helping in the design of the good scheduler. These criteria are as follows −CPU UtilizationThe scheduling algorithm ... Read More
The processes that are entering into the system are stored in the Job Queue. Suppose if the processes are in the Ready state are generally placed in the Ready Queue.The processes waiting for a device are placed in Device Queues. There are unique device queues which are available for every I/O device.First place a new process in the Ready queue and then it waits in the ready queue till it is selected for execution.Once the process is assigned to the CPU and is executing, any one of the following events occur −The process issue an I/O request, and then placed ...
