Router

Router is the networking device that is work on the layer 3 of the Open System Interconnection Model and that layer is network layer. This device is the very intelligent device. This device known as the layer 3 device and it is also known as the unicasting device for the data. Router is the device which is use to forward the data to the next router that exist in it's routing table. Router forward the packets to the other router for the delivery of the packets to it destination.

Following are the features of the Router:

Router is the complex task handler device.

Router is used for the sorting purposes and also for the distribution basically sorting will be done on the base of the network address and distribution will be done on the base of the host address.

Router is the one to one means unicast device for the data.

Router broadcast and multicast the for the exchanging of the routing table when dynamic protocol run.

Router is the device which is use to integrate Local Area Network and Wide Area Network.

Router is expensive device if it has more slots basically router price is the directly proportional to the ports of the router.

There are two port on the router for the access of the configuration terminal:

Console Port: By this port you can add the wire to PC and take configure terminal of the router.

Switch

Switch is the networking device which is also known as the layer 2 device and that layer is the data link layer of the Open System Interconnection Model. This device is the intelligent device than the hub networking device. This device is the device that is broadcasting when the switching table is not complete and if the switching table once complete then it broadcasting change into the unicasting. Switch is the device that is very helpful and used for the storing of the "Media Access Controller Address which is also known as the Mac Address and it's another name is physical address" of the connected devices. Switch is the device that has many ports and these amount of ports are greater than the ports of the Hub.

Following are the Switch Features:

It is also known as the Ethernet device.

Switch is commonly used in the Token Ring architecture and fiber channel architecture.

Switch is the device that can be works on the layer 2 and layer 3 that are Data link layer and Network layer respectively and that kind of switch is called the Multi Layer Switch (MLS).

Switch is the device that is use to find the source and the destination addresses of every packet.

Switch is also known as the router resembling device.

Switch is use to filter out the traffic.

Switch is the efficient device because of it's filtering traffic process.

Switch has the ability to set QOS.

Switch has the ability of the access control features.

Hub is the networking device and it stands for Hybrid Universal Broadcast which is known as the layer 1 device because it operate on the physical layer that layer is the first layer of OSI (Open System Interconnection) Model. This device is not intelligent device it is only responsible for the broadcasting. Hub is the device that is generally connect the computers in the Local Area Network. This device is very common device but in these days this device not use in the secure sector because of it behavior of the broadcasting. This device has many ports. This device only used for providing the connectivity to the end users.

Following are the features of the Hub networking device:

Hub is the device which is use to handle the data type which is known as the frames.

So the role of hub is that when it receives the frames it is transmitted the frames to the destination ports of the computers and it forward all the destinations that are connected in it's ports directly.

It deals with data types bits or signals of electric.

Hub is used in the small networks and small offices which is also called the SOHO networks (Small Office Home Office).

Hub device is the cheapest device in the networking devices.

It is very easy to install.

This device is the device that has no impact on the performance of the network.

It is the device which has no brain means has no ability for the identification of the best path.

And it is not used in the full duplex mode.

Hub has no capability to filter the the transmitted information.

Hub is a passive device.

Firewall can end up being explained as a system that has been devised aiming at the prevention of unauthorized and unnecessary access to or from a private system. It can be applied in hardware or software form seamlessly. Networks linked over the internet; majorly the intranets are guarded through these primarily as they are at major risks associated with unauthorized access.

Choosing the right firewall A device that has efficient and accurate features to save your business from malware, viruses and malicious cyber-terrorist is a daunting and much confusing task to accomplish. Firewalls come in different features and levels associated with security thereby making a fine choice is a lot more essential. To aid a person with making decisions associated with choosing the best firewall device here is your own guide which will educate a person for this method.

What is usually a Firewall?

A firewall is a device aimed at network security that is the software program that screens the traffic to plus from a particular network thereby blocking or enabling traffic by virtue associated with a set of predefined protection rules. The main focus associated with a firewall implementation is focused on the prevention associated with unauthorized access to a network majorly on the particular internet which is the particular most vulnerable of all.

Types of firewalls

Firewalls are mainly of three or more types of i. e. A software firewall, hardware firewall, and cloud firewall. Three of those are briefed about further-

1)    Software Firewall

A software firewall can be described as a product that is installed on your own device- computer, tablet, cellular phone, and so forth It provides no physical presence plus is installed locally which usually allows it to supply a much better level of accessibility and control thereby protecting the network in the and more effective way. Software firewalls block the particular traffic which is producing attempts to exit your device, unlike the equipment type.

2) Hardware Firewall

Simplified and direct enough, because the name suggests, a Next Gen firewall Device is a gadget that is connected to a computer of the network in order to keep the check within the malicious risks and protecting from illegal access. Hardware firewalls are usually often explained as routers with a lot associated with functions; specifically, the manage features. They let a person protect the complete network along with a single device.

3)    Cloud Based Firewall

Cloud firewalls are usually software-based network devices that are cloud-deployed aimed in stopping unauthorized access in order to private networks alike the other two firewall variants. With evolving cloud-based tech, the cloud firewall kind is devised to assist the modern business requirements and work successfully within online environments. These come out to be one of the best firewalls for business.
