Load TestingLoad testing is a type of non-functional software testing in which the execution of a software application is judged under a particular load. It controls how the software application works when a large number of people use it at the same time. Prior to deployment, load testing is done to detect performance bottlenecks and guarantee that software programs are stable and run smoothly.This analysis typically determines: -An application's maximum operational capacityExamine whether the current infrastructure is capable of handling the application.The app's viability in terms of peak user load is debatable.The maximum number of concurrent users supported by an ...

The ultimate goal of any software development company is to provide high-quality software. The software must be properly tested in order to reach this goal.As a result, testing is an important aspect of the software development process. As a result, it's critical that the software generated be evaluated by the developer (during the unit testing phase) and then delivered to the QC team to be extensively tested to guarantee that it has few or no flaws.Before being delivered to the actual test team for testing, the software is unit tested. This testing is done by the developer because it involves ... Read More
Fiber To The Premises (FTTP) is a fiber optic cable transmission system that enables an Internet service provider to access the Internet directly from customers or a group of users (ISP). It is one of the many fiber formulas for fiber delivery that is consistently composed under the umbrella name "Fiber to x" and is abbreviated in the same way.FTTP is significantly quicker than dial-up or coaxial cable Internet connections. This fiber optic communication delivery method involves deploying an optical distribution network that connects the central office to the subscriber's location.Categories of FTTPFiber to the premises is classified based on ...
