What are the uses of hubs?
The purpose of the hub is to arbitrarily choose a device for a specific port. Allow it to take up all the bandwidth for communication with the hub's uplink apparatus. The hub exhibits these two features when in operation.
The first point to note is that the Hub is merely a device that amplifies signals across multiple ports. When a data signal is sent from the source port to the Hub, the receiving port's signal strength decreases. Thus, the Hub reconfigures and boosts the signal. The weakened signal is restored to its original state and then sent to all other working ports.
The function of the Hub in the network is evident in its role, which is solely to amplify and retransmit signals. It helps the network reach further, but it can't send signals in a specific direction. It is a standard shared device.

However, as technology develops and needs change, many Hubs have broadened their functionality. The network that includes a Hub is a communal network, and a Hub can only function in half-duplex mode.
Hub is used to create a shared network and is a cost-effective way to connect servers to desktop computers. In a network with switching, the Hub is connected to the switch and sends data to the desktop. Hub networking is flexible. Situated at a star junction of the network, it centrally oversees the workstations linked to the junction.

A broken workstation won't disrupt the whole network, and users can freely join and leave.

LAN division
For Local Area Networks (LAN), there are five distinct categories of hubs.
(1) Individual Relay Segment Hub
The most basic hub is a kind of hub utilized in the most straightforward relay LAN network segment.

(2)Multi-segment hub
Use a hub backplane with multiple trunk segments. Users can spread out across different relay network sections, which is the main benefit. This helps to lessen the information traffic on each section. Data exchange between network sections typically necessitates separate bridges or routers.

(3)A port switching hub connects user ports to different network segments using a hub.
A hub implemented by adding a port switching matrix. PSM has a machine that lets any outside user connect to any part of the hub's backplane. The main advantage of a port-switched hub is the automation features of moves, additions and modifications.

(4)Network interconnection hub
Port-switched hubs focus on switching ports, while networking hubs connect multiple network segments on the backplane. This task is achieved via a unified network bridge, router, or LAN switch. This type of hub usually takes the form of a chassis.

(5)Transition to Hub
The distinction between hubs and switches has become increasingly unclear. Switched hubs have a core switched backplane that replaces traditional shared media trunk segments with a pure switching system.

Velocity
The selection of hub velocity is primarily influenced by these three elements.
(1) Bandwidth of the uplink equipment
If the uplink apparatus permits 100Mbit/s, it's logical to acquire a 100Mbit/s hub. Alternatively, a 10Mbit/s hub would be perfect. Because there are fewer devices connected to the network. And for networks where the communication traffic is not substantial, a 10Mbit/s hub can meet the application needs.

(2) Number of connection ports provided
Since all hubs linked to the station vie for the same upstream bus. Therefore, the greater the number of connected ports, the easier it is to cause conflicts. Simultaneously, information transmitted to any hub port will be distributed to all ports linked to the hub. Overloading with ports can diminish the efficient use of the device.

(3)Application requirements
When the content being sent doesn't include voice or visuals, and the amount of data being transferred is fairly low, opt for a 10Mbit/s speed. For large transmission volume and multimedia applications, choose a 100Mbit/s or 10/100Mbit/s adaptive hub.

Repeater
A hub is a unique type of repeater that can function as a switch for several network segments. Because several hubs can be cascaded. Intelligent hubs can also incorporate network operations like network administration and route choice.

The hub is the most compact unit that oversees the network and serves as the central connection point for the local area network. It centrally controls workstations to avoid issues in certain sections from disrupting the smooth functioning of the entire network. 

The hub is the most prevalent connectivity device in a LAN. Based on its setup, it can be categorized into three types: standalone hub, modular hub, and stacked hub. Its role can be simply perceived as linking numerous devices to establish a local area network.

In the widely used star topology, the hub (HUB) serves as the central component. If it malfunctions, the whole network will cease to operate, hence its quality is crucial to the overall network.
The above is an introduction to the use of hubs. By the way, hub and switch are two different things!
