Narrative Essay: The Switch

"Mother, please tell me the story before going to bed!" Concern excitedly begged. Mom said, "This is a late guy, I do not quite understand." "Oh, but I promised last night, I will tell you one thing to us tonight!" Ali complained. Mom finally gave up and pulled the chair. Children are fast and quiet, expecting to be crowded together. Mom breathed deeply, knowing that it is difficult for children to deal with the story being talked about. "My life is completely reversed, I am about to graduate at age 17," Mom said.

Switching is a method of sending frames over a network. Switching method determines how the switch receives, processes and forwards frames. Since many terms such as packet switching, circuit switching, etc. are related to the exchange, the concept of exchange can be confusing at some point. These are WAN implementations of Layer 2 LAN technology. To make this process easier to understand, I start learning from LAN and gradually expand it to WAN. Bridges and switches operate at Layer 2 (data link layer). Both the bridge and the switch can read the frame. Switching is a method of processing frames. Handover is described in layer 2 of the OSI model. The switch is an upgrade version of the bridge. The bridge is an initial implementation replaced by a switch.

Switch: A bridge that routes data in the OSI model DLL (Layer 2 - Data Link Layer). There are two types of switches: Layer 2 switch and Layer 3 switch. Each point of the switch functions as a direct communication point with the client computer. The switch provides a one-to-one relationship and identity to the server. When a packet enters the switch, the switch registers the MAC address and associates it with the port on the switch. If there is a packet to the destination, it will send the data directly over the port.

The term switch used by Novell represents a computer that accepts packets at the network layer and forwards packets to another network. The switch is a multiport bridge that processes and transfers the data link layer (layer 2) of the OSI model. Data Some switches have additional functions, such as the ability to route packets. These switches are often referred to as layer 3 switches or multilayer switches. Router - A router is a network device that transfers packets between computer networks (usually dedicated hardware). This creates an overlay internetwork as the router is connected to two or more data lines from different networks.
