Step-by-step explanation:

Computer firewalls perform several functions to protect networks from unauthorized access and potential threats.

• They check incoming packets to make sure that they have the right credentials: Firewalls analyze the source and destination addresses, ports, protocols, and other parameters of incoming packets to verify their authenticity.
• They check the behaviors of packets: Firewalls monitor the behaviors of packets, examining factors like packet size, data patterns, and time intervals to detect any suspicious or malicious activity.
• They watch packets: Firewalls actively monitor network traffic, inspecting packets in real-time to identify and block any unauthorized or potentially harmful packets from entering the network.
