What term describes measures that ensure system reliability by incorporating additional circuits and components?

The term that describes measures ensuring system reliability through the incorporation of additional circuits and components is referred to as "redundant measures." In the context of system design, redundancy involves having extra components or systems that can take over in the event of a failure, which enhances reliability and availability. This might include redundant power supplies, duplicate network connections, or additional hardware components that can seamlessly replace a failing part without causing downtime.

By having redundant measures in place, organizations can maintain consistent performance and availability of systems, even in the event of hardware failures or other issues. This is particularly critical in environments where uptime is essential, such as data centers or critical infrastructure.

Backup processes imply creating copies of data to recover from loss but do not necessarily involve additional operational components. Failover systems refer to the specific mechanisms that automatically switch to a redundant or standby system in case of failure, while scalability strategies focus on system expansion capabilities rather than reliability enhancements. Therefore, while those terms are relevant in the context of system reliability, they do not specifically encompass the broader concept of redundancy as a measure for ongoing reliability through the addition of circuits and components.
