A firewall is a device that sits between your computer and the internet, protecting your computer from unauthorized access. Many people think of a firewall as a switch, because it allows you to control which devices are allowed to connect to your computer.

In reality, a firewall is a router, because it allows you to control which devices are allowed to send and receive information on the network. .

A firewall can help protect your computer by blocking unauthorized access to your computer, protecting your computer from viruses and malware, and by protecting your data from being stolen. A firewall can also help protect your computer by blocking unwanted traffic from the internet, such as spam, pop-UPS, and ads.

A firewall can be installed on a computer or a router. A firewall can also be installed on a network.

A network is a collection of computers and devices that are connected to each other.
