A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.
What is a hub in computer?
A hub is the connection point in a computer device where data from many directions converge and are then sent out in many directions to respective devices. A hub may also act as a switch by preventing specific data packets from proceeding to a destination.
What is hub and its types?
The three types are active, passive and intelligent. Active hubs amplify the incoming electric signal, whereas passive hubs do not amplify the electric signal. Intelligent hubs are kind of active hubs.
What is hubs in data communication?
A hub, in the context of networking, is a hardware device that relays communication data. A hub sends data packets (frames) to all devices on a network, regardless of any MAC addresses contained in the data packet.
What is hub network device?
Hubs connect multiple computer networking devices together. A hub also acts as a repeater in that it amplifies signals that deteriorate after traveling long distances over connecting cables. A hub is the simplest in the family of network connecting devices because it connects LAN components with identical protocols.
What is hub in computer class 8?
Hub: A hub is a device that is used to connect computers in a network (Fig. 1.23). In a hub, when one computer sends data on the network, the hub simply forwards the packets to all the other computers connected to it (Fig. 1.26).

What is hub Javatpoint?
A hub is a common connection point, also known as a network hub, which is used for connection of devices in a network. It works as a central connection for all the devices that are connected through a hub. The hub has numerous ports.Furthermore, a hub is no IP address, as it is a dumb device.
What are the 3 kinds of hubs?
There are three types of network hubs: passive, active, and intelligent.
What does main hub mean?

What is repeater and hub?
Repeater has two ports: one for incoming signal and another one for boosted outgoing signal. Hub is able to join more than two signals. It takes the signal, boosts it, and transmits to all its ports. Typically hub can connect from 8 to 24 connections together.
What are the hub and network cables?
Cables Connecting Hubs and Switches. Two types of cables are used to connect devices to hubs and switches: crossover cables and straight-through cables. The difference between the two types is that in a crossover cable, two of the wires are crossed; in a straight-through cable, all the wires run straight through.
What is firewall class 8?

What is hubs in science?
In network science, a hub is a node with a number of links that greatly exceeds the average. Emergence of hubs is a consequence of a scale-free property of networks. While hubs cannot be observed in a random network, they are expected to emerge in scale-free networks.
What is hub in biology?
Complex networks (including most biological networks) are known as scale-free networks and are characterized by a power-law degree distribution.These high-degree nodes are called hubs. In protein-protein interaction (PPI) networks hubs represent proteins with a large number of interactions, called hub proteins.
