Answer:

DNS stands fro Domain Name System and it's the Internet's way of converting a user friendly alphabetic name (i.e. www.xyzcompany.com) into a network IP address (i.e. 99.125.132.10). DNS is also used within business networks to identify resources based on a name.

Answer:

Switch operates on Layer 2 of the OSI reference layer (the Data Link layer) while a router operates on Layer 3 of the OSI reference model (the Network layer). Switch allows communication between end points on the same network, whereas a router allows data to traverse more than one network. Switches map data by the MAC address whereas a router will map data based on an IP address.
