<prompt> Hlalosa tšebeliso ea firewall bakeng sa sistimi e sebetsang.nan  <response>: Instruction in English: Describe the use of a firewall for an operating system. . Response in English: A firewall is a crucial security feature for any operating system that helps regulate incoming and outgoing network traffic. A firewall works by monitoring the incoming and outgoing traffic and blocking or filtering any traffic that does not meet the set security rules or policies. This effectively prevents unauthorized access to and from a computer or network, safeguarding personal information and sensitive data stored on the system.Firewalls can be used to block malicious traffic, such as viruses, worms, and hackers, by examining data packets and determining whether they are safe or not. They can also be used to restrict certain kinds of traffic, for example, blocking specific websites, or limiting internet access for particular programs or users.Overall, a firewall serves as the first line of defense against online threats, ensuring the safety and integrity of the operating system and protecting it from unauthorized access or attacks. .
