What is a client and a server?

A client is the one who makes the requests and the server is the one who serves those requests. It's usually a computer hardware device or software that accesses a service made available by a server. Imagine you walk in a restaurant and order (request) some food for a specific dish (service) from the menu (available resources). The server is like the waiter who takes the customer's order, delivers it to the kitchen (processes the request), and brings back the prepared food (response) to the customer.

What are the benefits of following DevOps practices?

DevOps practices offers a multitude of benefits for software development and delivery, fostering a more collaborative, efficient, and reliable environment. DevOps practices create a culture of continuous improvement, faster innovation, and higher quality software delivery. Here are some key advantages: Faster Delivery and Deployment: DevOps practices heavily leverage automation for tasks like building, testing, and deployment. This streamlines the process, eliminates manual errors, and allows for more frequent releases. Code changes are integrated and tested continuously, catching bugs early and enabling quicker deployments with reduced risk. Improved Software Quality: DevOps bridges the gap between development and operations teams, fostering better communication and shared ownership of quality. Testing is integrated throughout the development life-cycle, not just at the end, leading to earlier detection and resolution of issues. Increased Reliability and Stability: Infrastructure prov

Explain STLC with an example?

Image
The Software Testing Life Cycle (STLC) s a set of phases that defines the testing approach for a software development project. It outlines the various activities and tasks involved in ensuring the quality and reliability of the software being developed. The STLC includes the following phases: Requirement Analysis: In this phase, testers analyse the requirements documents to understand what needs to be tested. They identify testable requirements, create test scenarios, and determine the testing scope. Test Planning: Test planning involves defining the test objectives, test strategy, test approach, and resources required for testing. Test plans and schedules are created based on factors such as project timelines, budget, and available resources. Test Case Development: Test cases are developed based on the test scenarios identified during the requirement analysis phase. Test cases outline the steps to be executed, the expected results, and the test data required for each test scenario. Te
