Maintenance and testing are critical phases in the software development lifecycle that ensure the system remains functional, reliable, and efficient over time. They involve regular updates, bug fixes, and performance evaluations to adapt to changing requirements and prevent system failures.

Maintenance And Testing

Maintenance and testing

The Software Development Lifecycle (SDLC) is a systematic process for planning, creating, testing, and deploying information systems, ensuring that high-quality software is delivered efficiently and cost-effectively. It encompasses various stages, each with distinct tasks and deliverables, to manage the complexity of software development and maintenance.

System functionality refers to the range of operations that a system can perform and how effectively it meets user requirements. It is a critical aspect of system design and evaluation, impacting user satisfaction and system efficiency.

System Functionality

System reliability refers to the probability that a system will perform its intended function without failure over a specified period under stated conditions. It is a critical factor in ensuring the dependability and efficiency of systems across various industries, impacting both performance and safety.

System Reliability

System efficiency refers to the ability of a system to achieve its objectives with minimal waste of resources, such as time, energy, and materials. It is often measured by the ratio of useful output to total input, and improving efficiency is crucial for optimizing performance and sustainability.

System Efficiency

Regular updates are like giving a toy a new battery to make sure it keeps working well and doesn't break. They help things like games and apps stay safe and fun to use by fixing any problems and adding new features.

Sometimes, things that are supposed to work together, like machines or computers, stop working because something goes wrong. It's important to find out why it happened so we can fix it and make sure it doesn't happen again.
