Along with the above devices, a number of other network devices, such as Firewall, Load Balancer, Proxy Server, Access Point, Modem, Content Delivery Network (CDN), VoIP Gateway, Network Attached Storage (NAS) etc are used in networking.

These network devices play vital roles in ensuring smooth and efficient data transmission. As network professionals or students, understanding their functions and knowing when to use each device is crucial. They enable us to connect, communicate, and share information across the world, making our interconnected world possible. In the next session, we will explore their configurations and practical applications in more detail.
