 ## __Layer 2__ Frames
 * ### Data Link Layer.
     * Packagers data int frames and transmits those frames on the network.

 * ### MAC Address 
     * Media Access Control
-    * Physical addressing system of a device which operates on the logial topology.
+    * Physical addressing system of a device which operates on the logical topology.
     * Uses a 48-bit address assigned to a network interface card.
