activare

Activare is a term used in Romanian to denote the process of making something active or operational. In general use, it describes enabling a device, feature, or service, as well as systematic steps that transition something from an inactive to an active state. The concept appears across science, technology, and daily life.

In science, activation refers to triggering or enabling a biological or chemical process. Enzyme activation converts an inactive enzyme into its active form. Receptor activation occurs when a signaling molecule binds to a receptor, initiating a cellular response. In chemistry, activation energy is the minimum energy required for a reaction to occur, a foundational concept in reaction kinetics.

In computing and information technology, activare refers to actions that enable software, services, or devices. This includes license activation, account activation, and device onboarding. In artificial intelligence, the term activation function describes a nonlinear transformation applied to a neuron's input to determine its output, a key component of neural networks.

In everyday use, activation can also mean starting or enabling a system, such as activating a smart home device, a subscription, or security features. Etymology: activare comes from Latin activare, via French activer, and has been adopted into Romanian with the sense of making something active.
