Five types of network device types are given below:

NAS (Network attached storage)

A NAS server is a server specialized to file storage. A NAS provides a central storage point for a LAN (local area network) that can be utilized for things like shared file access and storing user data backups. NAS devices are a cost-effective and straightforward approach to deliver network storage. As NASes begin to offer more advanced functionality suitable to small and mid-sized workplaces, the distinctions between a NAS device and a general-purpose server have been even more blurred in recent years.

Router

Routers are network devices that allow packets to be routed between networks. Everything from communication between several subnets within the same WAN to the internet connection that allows one to read this text is enabled by Layer 3 devices. This is a nice way to think about routers: They are the network equipment in charge of IP addresses.

Gateway

There is no difference between a gateway and a router in terms of hardware. Routers with a special function are known as gateways. Routers that serve as the default next hop are known as gateways. Packets are routed to the network's default gateway when there is no other route to an IP address on the network. The packets are then sent to their next ‘hop’ by the default gateway, and the process continues until the destination is reached.

Firewall

A firewall is a network security device that monitors traffic and, depending on a set of rules, either blocks or permits it. Software, hardware, or a combination of both can be used to create firewalls. Furthermore, firewall rules might be based on simple things like ports and IP addresses, or they can incorporate heuristics to detect malicious behavior.

Access Point

Access points, sometimes known as wireless access points (WAPs), are the network switches of the wireless world, operating at Layer 2. WAPs use a wired connection to connect to a LAN and allow other Wi-Fi devices to communicate. WLANs (wireless local area networks) are the networks produced by WAPs.
