Hello Dear

Firewalls do this by filtering data in network traffic to protect the network from a wide variety of malicious attacks and malware. Without firewalls to block cyber threats and prevent unauthorized access, computers and devices in your network are susceptible to attack.

hi, a firewall is a network security tool, either software or hardware, that blocks unwanted traffic and threats like malware. It uses pre-set rules to filter traffic and can include features like intrusion prevention systems (IPS) and URL filtering to block access to certain websites and applications.

Firewalls ensure that traffic from less secure environments, such as the internet, is authenticated and inspected before entering a more secure network. This prevents unauthorized access to your network.

A firewall is a network security solution that protects your network from unwanted traffic. Firewalls block incoming threats such as malware based on a set of pre-programmed rules. Modern firewalls also include additional capabilities such as intrusion prevention systems (IPS) and URL filtering etc to prevent users within the network from accessing certain websites and applications.

Firewalls are based on the simple idea that network traffic from less secure environments – like outside sources connected via the Internet – should be authenticated and inspected before moving to a more secure environment. This prevents unauthorized users, devices, and applications from entering a protected network environment or segment.

HI, A firewall is basically a tool that can be software or hardware that can block threats to a computer network that exist in one place, such as malware, botnet and others.
The firewall can be set in such a way as to block or allow any data packets to pass through your internal network, either from the internet to the LAN network, or vice versa.  
You can make regulation or policies for PCs or notebooks that can access the internet.
