Correct Answer:
C. To prevent unauthorised access to a private network
Explanation:
A computer firewall acts as a security barrier between a trusted internal network and untrusted external networks, such as the internet. Its main objective is to monitor and control incoming and outgoing network traffic based on predetermined security rules, effectively blocking unauthorized access while allowing outward communication. While other tools handle virus removal or password storage, the firewall specifically focuses on filtering traffic to prevent cyber threats from penetrating a private system.
