Routing is a process that includes moving data between two different devices. A router also has 2/4/8 ports and has a speed limit of 1-10mbps for a wireless connection that is, for a wired connection is has a speed limit of 100mbps. Switching is where the data is collected from a device and gets sent into multiple others but it is also based on what the MAC address is in order to do this. A switch also has 24/48 ports or called a multi port and a switch also has little to no collisions happen unlike a router has. The speed limit of a switch is 10/100mbps for wired and wireless both.

Great explanations on switching and routing. A routing table is a database that keeps track of paths, like a map and uses these to determine which way to forward traffic. A routing table is a data file in RAM used to store route information about directly connected and remote networks. A router can link both LAN (Local Area Network) as well as WAN (Wide Area Network) and transmit data to other connected networks. A switch can join multiple devices in a LAN.

In short, routing is the process of moving data between two devices. Forwarding is the process of collecting data from one device and sending it to another device. Switching involves collecting data from one device and sending it to multiple devices based on the MAC address of the packets. The fundamental difference between a switch and a router is that a switch belongs only to its local network and a router belongs to two or more local networks. Routing tables typically involve destination networks, less frequently do they involve individual host IPs. “Switch tables” as you call them are a lookup list, showing which hardware address (port) to send traffic. A Hub supports half-duplex i.e., only one device can send or receive data at a time while a switch supports full duplex i.e., both devices can send and receive data at the same time. A switch is located on the second layer of the OSI model while a Hub is located on the first layer. Layer 2 switches are faster than routers because they do not take up time looking at the Network layer header information. Instead, it examines the frame’s hardware address to determine what to do with the frame (forward, flood, or discard).

A router acts as a bridge between two or more networks such as a WAN like the Internet and a LAN such as an office or home network. A switch essentially allows you to take a single network port from a device and divide it into multiple ports allowing you to connect many more devices into a network. There are managed and unmanaged or “dumb” switches managed switches can perform some routing support such as VLANS and can be managed remotely over the network whereas unmanaged switches have no such features.

Switching is a process classified as layer two of the OSI model. Switching sends data to its destination at a faster rate than routing. Switches use MAC addresses to deliver data, but switches also listen to network traffic to determine the fastest route to send data, but if no route can be found, the port will become blocked and listen only. Switches are typically only used for local destinations for a single network. Switches also broadcast data, sending the data to all available ports.
Routing is a layer higher at level 3. Routing uses IP address to determine the destination of data, and such can be done between multiple networks. Routers have protocols that determine multiple destinations for packets.

You have detailed the differences of switching and routing in a great manner. Switchings is a very interesting method of communication, especially running the wires to various nodes on the network site. Combining the two methods can produce very efficient communications systems for large to medium networks.

Routing is a system used by routers to allow nodes nodes on a network to connect to other computer networks wirelessly. The router acts as a gateway for data and other connections coming in and out. This is also very similar to a wide area network in terms of connection range as using a router, the computer can connect to networks from around the world. This system of connection and communication is completed with IP addresses primarily.
Switching utilizes switches to connect multiple nodes on a network in order to communicate with one another. This is more in line with a local area network in the sense that each node is connected to an ethernet cord that runs to a port and is connected to a switch that handles traffic flow and what data goes where. This is completed using MAC addresses and allows for transmission between networks if necessary. Switches are not limited to LANs however and the switching method can be used to cover and entire campus for example.
