Personal Firewall
A personal firewall is a utility that detects and protects a personal computer from unauthorized intrusions. Personal firewalls constantly monitor all transmissions to and from a computer. When connected to the Internet, your computer is vulnerable to attacks from a hacker. A hacker is someone who tries to access a computer or network illegally. Users with broadband Internet connections, such as through DSL and cable Internet service, are even more susceptible than those with dial-up access because the Internet connection always is on.
Operating systems often include a personal firewall. Windows automatically enables its built-in personal firewall, called Windows Firewall, upon installation of the operating system. If your operating system does not include a personal firewall or you want additional protection, you can purchase a stand-alone personal firewall utility or a hardware firewall, which is a device such as a router that has a built-in firewall.
Network Firewall
In Internet Networking, Network Firewall refers to the means of securing the Networking Environment. So, Network Firewall can be Software based or Hardware based. Network Firewall refers to the means of securing Network, which includes blocking untrusted sources. The main objective is to control an outgoing or ingoing network traffic by analyzing it. And whether it should be allowed to pass through or not and its according to a set of rules or not. Network Firewall is like a Bridge between Internal Network that should be secured and External Network like Internet.
