Information
Definition
A worker is a device, service or software process that performs tasks under the direction of a controller, server or backend system. In modern controller-worker terminology it is commonly used as the alternative to “slave” in master-slave configurations, while in backend software it can also mean a background process that handles tasks such as messages, reports or diagnostics.
Why it matters
It matters because worker can describe both a subordinate charger/device in a controller-worker architecture and a backend processing component. Clear wording helps UK users interpret charger networking, load management and software architecture without relying on outdated master-slave terminology.
