Firewalls, Switches, Routers and VPN

Are you learning about how the business uses the networking systems? Well, you may be surprising why there is much essentiality on the difference between a switch, routers, firewall, and VPN networking systems. These four networking systems are basically designed to use for the Internet protocol. Keep in mind that these genres of networking systems are having different functionalities.

So, you need to understand the functionality and utilization process of these networking systems. Now, these networking systems are becoming essential for numbers of business. So, it is the perfect option for you to download the trail version of these networking systems online. You can also collect some information about these switch, routers, firewall, and VPN networking systems from previous users.

I am not saying this is not done and you may buy the big as well as expensive, chassis based, the Cisco 6500 series switch & have all the functions on various blades of switch. This is good for the larger business with the group of administrators however to the medium size business as well as single network administrator, lots of times, it is the scary thought. Remember that for the medium or else large size business, the integrated home devices will not work as they will not give all these features needed. Standalone routers, firewalls and switches, have a lot of more features than the integrated devices do. However, what is difference between the devices anyway? Let us now cover three most famous devices.


The router is the hardware device as well as has function of the routing packets between the networks. The router works at the Layer 3 of OSI model –Network Layer. It is a layer that IP protocol works. Most of the routers now are the IP routers, which examine source as well as destination IP addresses of every packet, look up destination of packet in router’s IP routing table, as well as route, which packet on the way.
