In this video i have talked about what is firewall and how does it effects our security on internet.

===========================================
ABOUT FIREWALL

In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.[1] A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed not to be secure or trusted.[2] Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls filter traffic between two or more networks; they are either software appliances running on general purpose hardware, or hardware-based firewall computer appliances. Host-based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine.[3][4] Firewall appliances may also offer other functionality to the internal network they protect, such as acting as a DHCP[5][6] or VPN[7][8][9][10] server for that network.
