RESTCONF and YANG are used for network configuration and management on Cisco IOS XE devices. RESTCONF provides a REST-like interface for accessing YANG-defined data models, allowing engineers to change configurations such as netmasks through programmable interfaces.

In version control systems, code review is typically performed before the code is merged into the main branch. The code review process involves evaluating the changes, ensuring they meet the project's coding standards, and identifying potential issues. This process helps maintain code quality and integrity before integration into the larger codebase.

The HTTP client error response code accompanied by a Retry-After header typically indicates that the client has sent too many requests in a given amount of time, leading to rate limiting by the server. This is often indicated by a 429 Too Many Requests status code. The Retry-After header informs the client how long it should wait before making another request.

Edge computing involves processing data closer to where it is generated (the "edge" of the network) rather than sending it to a centralized data center or cloud for processing. This approach reduces latency and bandwidth usage, providing high-speed data processing capabilities. It is particularly beneficial for IoT implementations where real-time processing and response are crucial.
