<h2>Device Categories</h2>
<p>
In a deployment of WoT conforming to the <a href="https://www.w3.org/TR/wot-architecture/#architecture-abstract">WoT Abstract Architecture</a>
we see different device types with typical characteristics.
They range (sorted in the order of footprint and capabilities)
from small embedded <em>node</em> devices to <em>gateways</em> or <em>hubs</em>

small does not imply resource constrained. Constrained or resource constrained embedded devices (like field devices) is more common.

to powerful <em>edge</em> devices and <em>cloud</em> servers.
Interoperability between these devices implies that a core set of features and functionalities
is available on <em>all</em> of them.
</p>

<p>The following device categories describe the footprint and characteristics of typical representants of these classes.
This is used to identify the possible features and use cases for these device classes.

<ul>
<li>Node - endpoint with typically 64-128 KB of RAM</li>

node only is unspecific. resource constrained node

typically 64-128 KB of RAM

I'm not sure about such a range. I would simple say typically KB of RAM

<li>Gateway/Hub - intermediate node, typically a few MB of RAM</li>
<li>Edge - </li>
<li>Cloud - multiple CPUs, virtualisation, large storage</li>
</ul>
