# Queues

{% hint style="danger" %}
Queues are deprecated and will be removed in version 5. They have been replaced by [Computer Groups](https://docs.powershelluniversal.com/v4-beta/platform/computers#computer-groups).
{% endhint %}

You can assign computers to queues by using application settings. By default, every computer is assigned to the default queue and a queue specific to the computer itself. When you assign a computer to a custom queue, that queue will be available in the admin console and you can use the queue for ad-hoc script execution and schedules. 

{% hint style="warning" %}
Queues with no active computers will queue jobs indefinitely. 
{% endhint %}
