Final answer:
In the field of computers and technology, we call this process live testing or staging environments. Live testing is when one environment is active while the other receives updates and serves as a testing environment. A staging environment refers to a separate environment that mirrors the production environment and allows for further testing or serves as a backup.
Step-by-step explanation:
In the field of computers and technology, we call this process live testing or staging environments.
Live testing is when one environment is active (usually the production environment) while the other receives updates and serves as a testing environment. A staging environment refers to a separate environment that mirrors the production environment and allows for further testing or serves as a backup.
For example, in software development, a staging environment is often used to deploy and test new features or updates before they are pushed to the live production environment.
