USB HUB fast charger 19 Port USB Hub with Integral power supply and Steel/Aluminum case

This is a 19 port hub With an integral power supply capable of

reliably supplying MORE that 500mA per port without overheating or becoming a fire hazard.

16 Front facing Standard A USB ports 3 Side facing Standard A 1 Master hub connection

Standard B for connection to Computing Equipment or other hubs Fully fused internally via multiple poly-fuse resettable fuses both on each individual port and on the main power feed to the Ports.

Unlike may of the cheaper USB ports that only implement links at 1.0 12mb/s speeds

(but state they are 'compatible' with USB 2.0)

this is a professional FULL 480 Mb/s port that complies and implements the full 2.0 USB standard,

it may also be used to connect to generic USB 1.0 equipment.

Answer 2

Mainly work of the HUB in a network that HUB is used to connect multi computers of different network in a single network.Different computers are connected with the hub with the help of individual ports and then perform different type o networking tasks as a single network.

so HUB provides communication between different network.and HUB is used for Broadcasting.

There is three types of Hub

1. passive:- The first type of the networking hub is the passive hub. Passive hub does not perform any particular function but it just behaves like a bridge between the cables of connection and just receives the information and forwards it with out any change in topology.

2. Active:- Second type of the networking hub is the active hub. This type of hub is quite similar to that of the passive hub but can perform the additional tasks. Active hubs are those hubs that can work as connector between two regions but also has ability to regenerate the information with the help of strong electrical signals. it is also called as the multi port repeater. It helps in the communication and can upgrade the properties of the signals before delivery.

3. Intelligent (managble):- The third and the last type of the hub that can perform the both functions of the active and the passive hub is generally referred to as the intelligent hub. Basically this hub provides the opportunity to increase the speed of networking and also make the performance of the network efficient as compared to other devices. Addition to their specific work intelligent hubs can also perform the different functions that of routing, bridging etc.

Answer 3

When a frame is sent from one computer to another, the hub retransmit it to all computers attached.
