# Comparison Component

### You can see the comparison component in:

* Scenario steps
  * Condition step
  * Search step
* Settings of scheduled scenario start
* Filters, Security Layers in API endpoint settings
* Filters and post-filters in Report settings

{% hint style="info" %}
Note that there is also a [data-type](/data/data-types.md)—operator;
{% endhint %}

Here is a standard Directual comparison component:

### The list of operators

There are following operators (lets compare **A** and **B**):

| Operator                       | Description                                                                                                                                                                                                                                                               | Example                                                                                                                                                                            |
