Yes, you can curl a wig with sponge curlers or any kind of curlers as long as you dont use any electronic tools on it. If your talking about a human hair wig only then can you â¦ use electronic tools. You can use curlers, and boiling water on a synthetic wig. Put the curlers in the hair, and boil water.
Routers and Layer 3 Switching. While most switches operate at the Data layer (Layer 2) of the OSI Reference Model, some incorporate features of a router and operate at the Network layer (Layer 3) as well. In fact, a Layer 3 switch is incredibly similar to a router.
The third layer of the OSI Model, the network layer, is where most network engineers focus their time and expertise. As Darragh commented in my post on the data link layer, Layer 2 is cool but Layer 3 is the one that can take you places. Layer 3, the network layer, is most commonly known as the layer where routing takes place. A router's main job is to get packets from one network to another. Layer 3 protocols and technologies allow for network-to-network communications.
