Types of Network Appliances

A network appliance is a device that performs a dedicated function for computer networks. These tasks generally involve protecting, monitoring, or optimizing data flow over the interconnected systems. Some examples of what they may do include firewall protection, intrusion detection, network monitoring, and optimizing data flow.

Network appliances are computer systems with hardware and software specifically designed to carry out these tasks. They are reliable and secure because they are engineered with purpose. The types of network appliances that exist often depend on the function they serve within a computer network.

However, many can be grouped into a few categories. The first category is a wide area network or WAN appliance. These appliances connect multiple network locations over a wide area. Locations separated by many miles can communicate with each other because of these devices.

The second type of appliance is a Local Area Network or LAN appliance. These devices connect network locations that are relatively close to one another, like within the same building or office space.

The third type of network appliance is a metropolitan area network or MAN. These devices connect locations over a medium geographic area. Examples of a MAN connection are appliances that connect network locations in the same city.
