Hub. A hub is a network connectivity device that you’re almost certainly familiar with. In the most basic sense, a hub is really nothing more than a multiport repeater. As signals are sent between systems connected to a hub, they are not only regenerated, but also forwarded out each port.

An hub acts as a multiport repeater

Normally they have multi-ple ports (this is why it was originally called “Multiport-Repeater”) and are able to connect to other hubs (using an uplink-port) and to a number of hosts (using a downlink-port). So it is still Hub. A hub is a network connectivity device that you’re almost certainly familiar with. In the most basic sense, a hub is really nothing more than a multiport repeater. As signals are sent between systems connected to a hub, they are not only regenerated, but also forwarded out each port. Answer: 4) A multiport repeater.

A hub works at the physical layer (layer 1) of the OSI model. The device is a form of multiport repeater. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision.

A hub in a 10Base-T Ethernet network is often known as a multiport repeater because it sends every input signal to all output ports. See 10Base-T and multiport bridge .

Active hubs, also sometimes referred to as multiport repeaters, regenerate the data bits in order to maintain a strong signal. Hubs are also used in star topologies such as 10BaseT. A multi-port twisted pair hub allows several point-to-point segments to be joined into one network.

It is aware of physical layer packets, that is it can detect their start 2021-02-28 Hub – A hub is basically a multiport repeater. coming from different branches, for example, the connector in star topology which connects different stations. Hubs cannot filter data, so data packets are sent to all connected devices. In other words, collision domain of all hosts connected through Hub … The repeater operates in the physical layer. Hub: A hub has a number of input lines that it joins electrically.

An active hub A passive hub either (a) or (b) neither (a) nor (b). In which layer of the OSI Model, Routers works. Back> The most common network devices are repeaters, hubs, bridges, switches and routers. Hub is a multi-port repeater.

The repeater is made up of a 2 port by default so the hub is called multiport. Multiport-Repeater Basics A special kind of a repeater is the “Multiport-Repeater”. Colloquially, it is almost always described as hub or common hub. However the term “hub” is in literature also used for other network devices or objects such as switches, routers, bridges, airport-hubs and so on.

Hubs cannot filter data, so data packets are sent to all connected devices. In other words, collision domain of all hosts connected through Hub remains one. In a word: a hub is almost a multi port repeater.

Hub: A hub has a number of input lines that it joins electrically. Active hub and passive hub are two types of hubs. Frames arriving on any of the lines are sent out on all the others. It is broadcast device. If two frames arrive at the same time, they will collide, just as on a coaxial cable.
