# Device Terminology
- **Device** — the player computer or unit running the Beacon client.
- **Device ID** — the player identifier used by the player to identify itself.
- **Display** or **Screen** — a physical output attached to the Device, defined by its pixel width and height. A Device can have from one to six displays.
- **Device group** — a named collection used for targeting messages or Automation actions.
- **Online status** — the live connection state supplied through Beacon's status WebSocket.
- **Last seen** — the most recent time Beacon received the device online or heartbeat state.
- **Authentication token** — the credential issued to an authenticated player.
- **Assignment** — an Information Display or Playlist associated with the Device.
#### **What is a Device?**
A Device represents an Acquire player computer and its attached screens. Its screen dimensions allow Beacon to generate correctly sized emergency-message images. Devices can be grouped and can receive individual Information Displays, Playlists, or both.
The Devices list
Open **Devices** from the navigation. 
The table shows:
- **Status** — green when online, orange when recently seen but offline, and red when never connected or not seen for at least 24 hours. Hover for **Online**, **Never connected** or a relative last-seen time.
- **Name** — hover to see Device ID and description. This column can be sorted.
- **Project** — shown when viewing records across all projects.
- **Displays** — screen dimensions, shown on wider windows.
- **Groups** — assigned Device groups. This column can be sorted.
- **Playlists** — assigned playlists.
- **Information Displays** — directly assigned displays.
- **Operations** — Assign, Edit, Preview, Reset Token and Delete.
#### **Actions**
- **New Device** — opens the Device form.
- **Assign** — replaces the Device's direct Information Display assignments.
- **Edit** — changes identity, screens, groups and direct displays.
- **Preview** — opens the player client for this Device in a new browser tab.
- **Reset Token** — clears the current token and tells the player to authenticate again.
- **Delete** — removes the Device and forces any connected player using it to re-authenticate.
Playlist assignments are managed from the Playlists list or by Automations.
