1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.

What resides at the physical layer of the OSI layer?
Interfaces used on the system to connect to Network devices reside on Physical layer.
Connectivity devices such as hubs and repeaters operate at which layer?
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
Amplifier work in which layer in osi layer?
Layer 1 - the physical layer
How is time measurable by physical devices if it is not a physical quantity?
Well, some physical devices don't work at all.
What layer of osi model is modem work?
physical layer Layer 1
What is the physical layer of the OSI model designed to do?
hub work at physical layer of osi model
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
What devices operate only at the Physical layer of the OSI model?
All network devices have some component that operates at layer 1. Only hubs and repeaters operate entirely at layer 1.
What network devices works at Layer 1 of the OSI model and connects multiple Ethernet segments together?
Physical layer devices would be a hub or a repeater to connect multiple Ethernet segments together.
Hub work on which layer in osi?
TheHub work on layer 1 i.e. Physical layer of OSI Model
Discuss allthe network devices used indifferent layer oftheosi model?
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
Does a switch work at the physical layer?
No...the physical layer is just that: The wires or COAX or fiber that physically makes up your network. If the switch were to work at a physical layer it would literally be opening or closing contacts to make the wires joined together be disconnected or connected...which is NOT the case, there is no physical opening/closing going on. Switches I was trained on (in the mid-80's) worked based on MAC addresses of devices, that unique only-this-one-device-in-the-world number burned into end units. Or there is a possibility they might work higher up the protocol chain, on the Ethernet Address. it's been too long since I was involved with zeros and ones. But certainly not on the physical layer. Hopefully someone with more recent experience will update this answer for you...
