A few days ago, we introduced what a hub is. Can we classify hubs? That's for sure!
Generally speaking, we can subdivide it according to the two major categories of hub processing and its structure.
Classified by processing...
HUB can be categorized as passive, active, smart, or other based on how it handles input signals.
Passive HUB
The worst quality and does not do any signal processing. The medium's transmission distance does not have an extension, and it significantly affects the signal. Every computer linked to this HUB can access signals from all other computers connected to the same HUB.
Active HUB
The distinction between an active HUB and a passive HUB is that the former can boost or regenerate signals. This method enhances the successful communication range between two systems.
Intelligent HUB
Beyond the capabilities of an active HUB, an intelligent HUB incorporates network administration and routing features. Within an intelligent HUB network, not all devices can intercept the signal. Only the computer that shares the same address port as the signal's target address can intercept it. Some intelligent HUBs can autonomously select the optimal route, offering excellent network management!
Other
In line with other techniques, there are numerous kinds, like 10M, 100M, 10/100M adaptive HUB, and so on.

Classified according to structure and function...
Hubs are divided into three types: unmanaged, stacked, and chassis hubs.
(1)Non-configurable Hub
The most basic hub offers centralized network connectivity through an Ethernet bus, arranged in a star layout. This is known as a non-configurable hub and is solely utilized in very small networks with a maximum of 12 nodes.
Non-configurable hubs lack management software or protocols to deliver network management features. These hubs can either be passive or active. Active hubs are more commonly used.
(2)Stacked hub
Stackable hubs are a bit more intricate. A stacked hub can connect 8 transponders together, which is its most important feature. This allows you to expand your network by simply adding hubs and connecting them to already installed hubs. This approach is not just cost-effective, but also straightforward and effortless to put into action.
(3)Hub of the chassisA chassis hub
Hub of the chassisA chassis hub is a device where different modules can be plugged into its circuit board. Certain hubs are equipped with duplicate backplanes and power supplies. Concurrently, some modules enable users to substitute malfunctioning modules without having to power down the entire hub.
The hub's backplane sets up several buses for the insertion of modules. These modules can be used for different types of connections like Ethernet, Fast Ethernet, and fiber optic data interfaces. Certain hubs may also incorporate bridges, routers, or switch modules. Active frame hubs might also be linked with retiming modules that are associated with amplified data signals.
There are two main types of hubs. These hubs can be set up, handled, or organized. They are then divided into various subcategories.
