+        <h1>The Purpose and Characteristics of Embedded Systems</h1>
+        <p>An <strong>embedded system</strong> is a computer system with a dedicated function that is usually part of a larger mechanical or electrical system.</p>
+        <p>They are usually based on microcontrollers or microprocessors, keeping the power consumption and cost per unit low.</p>
+        <p>There is no operating system installed on an embedded system. Instead, firmware is usually created and flashed to the microcontroller.</p>
+        <h1>Examples of Embedded Systems</h1>
+        <p>Some notable examples of embedded systems are:
+            <ul>
+                <li>Washing Machines</li>
+                <li>Traffic Lights</li>
+                <li>Engine Management Systems</li>
+                <li>Medical Instruments</li>
+                <li>Factory Machines</li>
+            </ul>
+        </p>
+        <p>These devices are <strong>not</strong> examples of embedded systems, and are considered as <strong>general purpose systems</strong>:
+            <ul>
+                <li>Desktop Computers</li>
+                <li>Laptops</li>
+                <li>Smartphones</li>
+                <li>Tablets</li>
