What else can I help you with?
Discuss allthe network devices used indifferent layer oftheosi model?
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
What layer do hubs operate at in the OSI model?
Its at Layer 1 of the Open Systems Interconnection Model (OSI model) Layer 7 Application Layer 6 Presentation Layer 5 Session Layer 4 Transport Layer 3 Network Layer 2 Data Link Layer 1 Physical
What is the physical layer of the OSI model designed to do?
hub work at physical layer of osi model
Hub work on which layer in osi?
TheHub work on layer 1 i.e. Physical layer of OSI Model
What is the difference of a hub and a switch?
1)Hub is a layer 1(physical layer)device whereas switch is a layer 2(datalink) device. 2)Hub sends data to all ports unnecessarily.so in this way it shared bandwidth whereas switch sends data to exact that port which required it after learning destination MAC address.so here is a dedicate bandwidth.

What are the features of hub?
at the physical layer ,hub can support little in the way of sophisticated networking. hubs do not read any data passing through them and are not aware of there source and destination.
What is a central device through which data bound for a work station travels in?
HUB
Which Network devices work at Layer 1 of the OSI model and connects multiple Ethernet segments together?
Hub
What is the difference between the router and the hub?
A hub (or L2 switch) performs data bridging/switching/forwarding at the OSI Layer 2 level for data destined to another address on the same subnet. For data to be forwarded to another subnet, that data must be routed at the OSI Layer 3 level which is performed by a Router (or L3 Switch). Routers collect various information about other networks it can forward traffic to and from, what routing protocols are used and which path(s) to forward that data to.
What is the Difference between modem and hub?
This is actually just a modem. A hub is a device with multiple ports for connecting computers to each other. A hub is now rarely used as a network switch is a faster more reliable device. Confusion comes from people like BT who supply what they call a home hub, which is actually a wireless router, they use the term home hub to refer to the central point (as in hub of a wheel) connection, probably because it's bright young designers never heard of a network hub! A modern wireless router normally consists of a combined router, 4 or 5 port network switch and wireless access point in one, and a non wireless one is the router and network switch Mohammad Talha 009746411902
What are the devices used in session layer in osi?
What_are_the_devices_used_in_osi_transport_layerNetwork Devices Used in Transport Layer: The Brouter (Bridge router), Gateway and Cable tester work on the transport layer.for more about devices used in 7 layers of OSI model go: http://www.networktutorials.info/osi_layers.html
Where does a hub send data?
