A firewall is a piece of software that sits between a computer and the network to which it is connected. All network traffic to and from the computer passes through this firewall.
The function of the firewall.
The firewall scans the network traffic that flows through it, which filters out some attacks before they are executed on the target computer. Firewalls can also shut down ports that are not in use. It also prohibits outgoing traffic on specific ports and blocks Trojan horses.
Finally, it can prohibit access from special sites, preventing all communication from unknown intruders.
Why use a firewall.
Firewalls are very protective. The intruder must first traverse the security lines of the firewall before they can reach the target computer. You can configure your firewall to many different levels of protection.
The type of firewall.
There are different types of firewalls. A firewall can be part of the hardware itself, and you can plug both the Internet connection and the computer into it. A firewall can also run on a stand-alone machine that acts as a ** and firewall for all the computers in the network behind it.
Finally, machines directly connected to the Internet can use personal firewalls.
The firewall is like a protection net, allowing useful information to pass through and put the virus down, but it can't reach 100% of the screen; Antivirus software kills and removes viruses that enter your computer, and it is also difficult to achieve 100% killing.
It's not the same, it can be used together.
