# Device (classic)

A *device* is an object that represents any personal computer or computerized system from which Nexthink can extract information to produce end-user analytics.

Nexthink classifies devices into three types:

**Desktop**

A conventional or virtualized personal computer running a client version of either Windows or Mac operating systems.

**Laptop**

A portable personal computer running a client version of either Windows or Mac operating systems.

**Server**

A computer that provides functionality (e.g. email, web, or directory services) to client computers (desktops and laptops) and runs a version of the Windows Server operating system.

### Licensing <a href="#device-classic-licensing" id="device-classic-licensing"></a>

The licensing model of Nexthink is based on the number of devices of the different types in your setup. For licensing purposes, desktops and laptops are both considered **endpoints**; that is, regular devices that support the installation of the Collector.

Thus, when licensing your product, provide the number of:

* Endpoints (desktops plus laptops)
* Servers
