System integration is the process of combining different subsystems or components into one comprehensive system. This involves ensuring that the subsystems work together seamlessly to achieve a specific goal or function. System integration often involves integrating hardware, software, and network systems to create a unified system that can perform various tasks efficiently. This field is critical in various industries, including technology, engineering, and telecommunications, as it helps improve the overall performance and functionality of complex systems. The goal of system integration is to streamline operations, enhance communication between subsystems, and provide a more cohesive and effective solution for end-users.
