### The DCAF Components

Before you begin the installation, you should be familiar with the DCAF components. The role of each workstation in your network determines the component(s) you install on that workstation. All components, except targets, run on OS/2 workstations only.

You can install one or more components on the same workstation, but it is recommended that you install only the necessary components on each workstation. For example, on one workstation you might install a controller , on another, the gateway and LAN directory, and on a third, a target component.
