What does firewall software do?

• A. Software that allows you to control which programs can access the internet and protects your device/network from unauthorised access
• B. Software that scans for viruses
• C. Software that backs up data to cloud
• D. Software that manages email settings

Answer: (A)

Firewall software acts as a gatekeeper for network traffic. It watches the data trying to go in and out of your device or network and applies rules about which programs or services are allowed to reach the internet. By doing this, it blocks unauthorized access and helps prevent attackers from reaching your device, while letting legitimate applications communicate. It’s not about scanning for malware, backing up data, or adjusting email settings, which are handled by antivirus, backup, and email tools respectively. Common examples include Windows Defender Firewall or a home router’s built-in firewall.
