It teaches you what routing is, what the purpose of the data link is when network congestion can occur and also whether a bridge divides a network into smaller sections. When a switch is given a signal, it develops a frame from the parts that are from the signal. Through this process, it gains access and reads the address of the destination. Post this it sends the frame to the appropriate port. This is a very effective means of data transmission, in spite of broadcasting it on all ports.
Switches can also avoid loops through the use of spanning tree protocol. Switches work on hardware addresses to exchange data across the devices that are connected to them. Adding to this, Hubs cannot even process data based on if it is broadcast, unicast or multicast data. In contradiction to this switches first, perform broadcast and then unicast. Hubs only work in half-duplex mode. Also, collisions can happen. In case a collision does happen, hub rejects all the data from all the devices then signals them to send the data again.
Bridge and switch are different in a way that a switch forwards data at wire speed as it uses ASICs that are special hardware circuits. Switches support full duplex data transfer communication. Switches cannot be used in large networks that are divided into sub-networks because they cannot forward networks or database.
Using spanning tree protocol, switches can avoid loops as well. Routers , unlike switches and hubs, operate at the third layer of OSI models. Due to these, routers can forward data across networks. Routers are very rich in features when compared to switches. They maintain a routing table for data forwarding.
They also have lesser port densities if compared to switches. If you are for the IT sector or have a background in network engineering, you have a great opportunity of enhancing your professional profile. Everybody is moving towards the IT job market these days; therefore, you need to stand out from the crowd.
The Cisco Certified Network Associate certification is a very good opportunity for you to do that.

Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device called routers, which are network layer devices. The job of the Data Link layer is to check messages are sent to the right device. Another function of this layer is framing. When a switch receives a signal, it creates a frame out of the bits that were from that signal. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port.

Edit Reply. Cisco interview questions are a must to know if you are attending the Cisco on-campus or off-campus drive. These will give you an idea of what questions were asked for various roles. Before you check these questions, you can go through.
How did you feel about that experience? Be very thoughtful about your answer. This is a very serious matter for most companies and requires a very serious answer.

Don't forget that firing is not the same as laying someone off - it typically is for the direct benefit of the company.
