Final answer:
During the operation and support phase, hardware or software updates are regular and crucial to maintaining system functionality and security.
Step-by-step explanation:
During the operation and support (O&S) phase, hardware or software updates are regular and crucial. The O&S phase is characterized by ongoing maintenance and enhancement of the system. This phase involves continuous monitoring, performance analysis, and the implementation of necessary updates to the hardware and software to ensure system functionality and security. Regular updates are critical to address new security threats, improve system performance, and add new features.
Software updates often include patches for security vulnerabilities, enhancements to functionality, and improvements in performance. Hardware updates might be required to improve capacity, reliability, or to keep up with technological advancements and compatibility demands.
