what is hub and switch in networking?
51622
a hub. A switch is used to connect various network segments. A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). A Hub connects multiple Ethernet devices together, making them act as a single segment.

Hubs are layer 1 devices,Hubs are just splitters. ... Hubs unlike switches do not have any intelligence and do not process packets in any way. They just send all the data received on the hub out to all the other active ports on the hub with the exception of the incoming port.

A hub, also called a network hub, is a common connection point for devices in a network. Hubs are devices commonly used to connect segments of a LAN. ... When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

['Hubs are “dumb” devices that pass on anything received on one connection to all other connections.', 'Switches are semi-intelligent devices that learn which devices are on which connection.', 'Routers are essentially small computers that perform a variety of intelligent tasks.']

Switches are used to connect multiple devices on the same network within a building or campus. For example, a switch can connect your computers, printers and servers, creating a network of shared resources. The switch would serve as a controller, allowing the various devices to share information and talk to each other.

A core router/switch is a device that connects to core and edge routers for the primary purpose of allowing transit traffic to flow from one end of the network to the other. An edge router/switch is a device that connects to core routers on one side, and devices that are external to the network on the other side.

8. Which of this is not a network edge device? Explanation: Network edge devices refer to host systems, which can host applications like web browser. A switch can't operate as a host, but as a central device which can be used to manage network communication.

Hubs are classified as Layer 1 devices per the OSI model. To connect a network of personal computers together, they can be joined through a central hub. Directs data in a network. ... A router is a networking device that connects a local network to other local networks.

A core switch, also known as a tandem switch and a backbone switch, is a high-capacity switch positioned in the physical core, or backbone, of a network. In a public Wide Area Network (WAN) a core switch serves to interconnect edge switches, which are positioned at the network edge. ... See also switch.

Switch is a layer 2 device which works on the basis of MAC address (physical address) of a device. Switch mainly performs these functions: ... (a) Unicast: The switch unicast the frame to the destination only when it has an entry for destination MAC address in its MAC address table.

In most cases, hubs are wired devices and you use LAN cable between it and all other connected devices. ... Modems are used to connect to the internet while hubs are used in Local Area Networks. A modem is used as an interface between a digital and analog network while a hub is all digital.

Top-of-rack switching is a network architecture design in which computing equipment like servers, appliances and other switches located within the same or adjacent rack are connected to an in-rack network switch. The in-rack network switch, in turn, is connected to aggregation switches via fiber optic cables.

NETWORK SWITCH  A network switch is a device used to connect network segments or network devices. ...  Network switch forwards data to one or multiple devices that need to receive it.  Switches are the multiport network bridges that process and forward data at the data link layer(layer 2 of OSI model).

['Repeater – A repeater operates at the physical layer. ... ', 'Hub – A hub is basically a multiport repeater. ... ', 'Bridge – A bridge operates at data link layer. ... ', 'Switch – A switch is a multi port bridge with a buffer and a design that can boost its efficiency(large number of ports imply less traffic) and performance.']
