Explanation

A firewall is a network security device (or software) that monitors all incoming and outgoing network traffic and filters specific packets based on predefined security rules, allowing or blocking traffic accordingly. A switch forwards data frames between devices on the same network but does not filter based on security rules. An access point extends wireless network coverage. A modem modulates and demodulates signals to connect a network to an ISP but does not perform packet filtering.
