<p>In this section you will learn how to get overall memory information (usage by OS) and memory module layout:</p>
|
|
<p>For function reference and examples we assume, that we imported <span class="code">systeminformation</span> as follows:</p>
|
|
<pre><code class="js">const si = require('systeminformation');</code></pre>
|
|
<h2>System Memory and Memory Layout</h2>
|
|
<p>All functions in this section return a promise or can be called with a callback function (parameter <span class="code">cb</span> in the function reference)</p>
