Hardware Component Requirements for Networked Media Devices (Windows CE 5.0)
The following table shows descriptions of the requirement levels for the hardware components of networked media devices (NMDs).
| Requirement level | Description |
|---|---|
| Required | Necessary for an NMD. |
| Recommended | Suggested for added capabilities, improved performance, and a better user experience. |
| Optional | Not required or recommended, but may provide product differentiation. |
The following checklist shows the requirement level for each hardware component. For information about developing device drivers for NMDs, see Developing a Device Driver.
