Software life cycle: Software life cycle is the concept in which software is developed and coded, and it has evolved over the time. The software life cycle includes the following phases to build new software. They are as follows: Phases of software life cycle: Requirements: It is the first phase of the software life cycle. This process is used to analyze the requirements of the customer. It gives the abstract idea what they really need as an end of the result. Specifications: It is the second phase of the software life cycle. It reflects the functionality needed to meet the requirements. Design: It is the third phase of the software life cycle. It defines the required features and operations through the process diagrams, software architecture, algorithmic details, and interface representations. Implementation: It is the fourth phase of the software life cycle. In this phase, programmers do the code for the above requirements and designs. Maintenance: It is the last phase of the software life cycle. It makes the missing requirements as changes to redesign the software that takes some time and effort to enhance the software.
