FireWall
A firewall is a dedicated appliance, or software running on computer, which inspects network traffic passing through it, and denies or permits passage based on a set of rules.
A firewall's basic task is to regulate some of the flow of traffic between computer networks of different trust levels. Typical examples are the Internet which is a zone with no trust and an internal network which is a zone of higher trust. A zone with an intermediate trust level, situated between the Internet and a trusted internal network, is often referred to as a "perimeter network" or Demilitarized zone (DMZ).
A firewall's function within a network is similar to physical firewalls with fire doors in building construction. In the former case, it is used to prevent network intrusion to the private network. In the latter case, it is intended to contain and delay structural fire from spreading to adjacent structures.
Without proper configuration, a firewall can often become worthless. Standard security practices dictate a "default-deny" firewall ruleset, in which the only network connections which are allowed are the ones that have been explicitly allowed. Unfortunately, such a configuration requires detailed understanding of the network applications and endpoints required for the organization's day-to-day operation. Many businesses lack such understanding, and therefore implement a "default-allow" ruleset, in which all traffic is allowed unless it has been specifically blocked. This configuration makes inadvertent network connections and system compromise much more likely.

What is a Computer Firewall?
Firewall is a computer program that monitors the flow of information from the Internet to your computer. There are two different types of firewall available for you to use - Hardware Firewalls and Software Firewalls.
Hardware Firewall:
A Hardware Firewall is a physical piece of equipment that sits between the Internet and your computer. An example of a hardware firewall is a broadband router, a common form of Internet connection. The benefit of using a hardware firewall, is that it has the ability to protect multiple computer systems that are connected to it at the same time. This makes it an effective firewall for use in businesses that have multiple computers connected to the Internet, as well as in homes that have more than one computer system.
Software Firewall:
Software Firewalls work in the same way as a hardware firewall, by monitoring and blocking information that comes to your computer via the Internet, however software firewalls must be installed as a program on your computer. These software firewalls can either be installed from a computer disk that you have purchased, or downloaded over the Internet. Software firewalls are the most common type of firewall. Programs such as Norton 360, Norton Internet Security, ESET Smart Security, and Kaspersky Internet Security all have a firewall bundled within them.
What a Firewall does:
Regardless of what type of firewall you choose to use, having one on your computer is a really good idea. A firewall helps to prevent computer hackers from accessing your computer through the Internet, and stealing sensitive information or infecting your computer system with some form of computer virus. A hacker can gain access to your system by �back doors� or open ports that connect your computer to the Internet. With a firewall in place these ports are blocked from inbound traffic, effectively closing the door in the hackers face.
Of course, damage can also be done to your computer from outbound traffic as well. Say for instance a hacker was able to slip by you with a Trojan, virus, spyware or phishing scheme that went undetected. The next time you booted up your computer and connected to the Internet, information on your computer could be sent out to the hacker. Many firewalls also block outbound traffic that will help prevent this from happening.
There are basically two ways that Firewalls work. Generally, data that comes in is analyzed by the firewall to determine the IP address it is coming from and the content that it contains. The firewall system then checks to see if this information is compliant with rules that you are able to configure. It can also analyze information at the application level. The firewall program will determine whether or not the application should be able to send or receive data through the port you are connected by.
Firewall programs are extremely important to the protection of not only your computer system, but you personal information as well. Many anti-virus programs come with firewall protection. Firewall protection should be considered an essential part of any computer's security strategy.

I know that a firewall blocks traffic or networks that are intruding and that are possibly untrustworthy or not permitted. I know at my job we have a firewall that blocks attacks from other computers, viruses, etc. I am wondering though about my home computer. I have enabled my firewall on my computer and I do have Mcafee, but have been told I do not need them because my ip provider has a firewall built in. Is this accurate or not? Thanks.

Firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices which is configured to permit or deny computer based application upon a set of rules and other criteria.

Lots of good points and description of what a firewall is. One important lesson for me is that even if you are running an excellent virus protection suite, addware and malware detection , your firewall also protects your computer from the network. You authorize what goes in and what goes out. Even if you have a hardware firewall built into your router , that still doesnt monitor what goes out from you computer in most cases. Using a good software firewall program not only gives you a database of problem sites , it makes you authorize communication with sites on the internet. When that box pops up and informs you that a program is trying to contact a site and you are not running anything that is going out to the internet , you now have a strong indication your protection has missed something ! ;D

A firewall is a piece of computer system or network, which is designed to prevent unauthorized access, enabling communications authorized. It is one or more devices that are configured to allow or block network transmissions are based on standards and other criteria. Firewalls can be implemented either in hardware or software, or both. Firewalls are frequently used against unauthorized Internet users from accessing private networks, Internet access, especially intranets. All messages entering or leaving the intranet pass through the firewall, which checks each message and blocks those that do not meet the specified security criteria.

Firewall (computing), a technological barrier designed to prevent unauthorized or unwanted communications between computer networks or hosts.Internet firewall protecting the nation from the hostile invasion of a private local area network. Consequently, many LANs are now connected to the Internet where the connection could have been too risky to the Internet.

A firewall is a secure and trusted machine that sits between a private network and a public network.[1] The firewall machine is configured with a set of rules that determine which network traffic will be allowed to pass and which will be blocked or refused. In some large organizations, you may even find a firewall located inside their corporate network to segregate sensitive areas of the organization from other employees. Many cases of computer crime occur from within an organization, not just from outside.

Basically, a firewall is a barrier to keep destructive forces away from your property. In fact, that's why its called a firewall. Its job is similar to a physical firewall that keeps a fire from spreading from one area to the next.

Firewall is a security system which protect the System from Intruders and hackers. Firewalls also safeguards the PC from offensive software that come to reside on the software to stole the user personal data.
It is a software programs or hardware tool which notes and filters the traffic that flow into the PC through Internet connection. They block the files which are harmful to the system. There are set of rules to connect such as who to connect to the internet, what kind of connections can be made to the internet, what kind of files may be transferred. These Rules are can be set up by yourself or by administrators to allow traffic to their web servers, FTP and Telnet servers, thereby giving the computer owners/administrators control over the traffic that flows in & out of the systems.

Conceptualize internet traffic as road traffic in the form of trucks. The firewall is border security that separates your home from your (untrusted) neighbouring countries.
Each truck that wants to enter the country has papers that tell the border security officer what the origin of the truck was (IP address of sender), where the truck wants to deliver its load (port/application that is going to receive the payload) and the order form of the one who requested the load (this is the web page you clicked on in your browser).
More advanced firewalls will also want to look inside your truck to see if there are goods you're trying to smuggle in (malicious payload).
Whenever the border security officer sees something it doesn't like, it denies the truck entry.
Firewalls are also able to work in the outgoing direction. Here, the border security officers check if the truck wanting to leave the country is legit and whether it's trying to smuggle contents out (a virus within your system is trying to send your personal data to a criminal).
