What are the benefits of using a firewall?
A firewall is a security system that helps protect your computer from unauthorized users who might try to gain access to your computer through the Internet. By using a firewall, you can help safeguard your personal information and prevent others from gaining access to your computer without your permission.
When you connect to the Internet, your computer is assigned an IP address. This address is like your computer’s street address and allows other computers to find and communicate with your computer. If you do not have a firewall, anyone who knows your IP address can access your computer. A firewall helps prevent this by blocking all traffic from computers that do not have permission to access your computer.
In addition to blocking unauthorized access, firewalls can also help protect your computer from certain types of viruses and other malicious software. By blocking incoming traffic from known malicious IP addresses, a firewall can help keep your computer safe from harm.
There are two main types of firewalls: hardware and software. Hardware firewalls are physical devices that are installed between your computer and your Internet connection. Software firewalls are programs that are installed on your computer and work with your operating system to protect your computer.
Both hardware and software firewalls can be effective in protecting your computer. However, for the best protection, it is recommended that you use both a hardware and a software firewall.
How does a firewall work?
A firewall is a system that helps to protect your computer or network from unauthorized access. Firewalls can be hardware devices, software programs, or a combination of both. They work by filtering the incoming data from the Internet and allowing only the data that is safe to pass through. Firewalls can also block outgoing data that might be harmful to your computer or network.
