Modem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. That is the definition of Layer 1.
What else can I help you with?
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
Amplifier work in which layer in osi layer?
Layer 1 - the physical layer
Hub work on which layer in osi?
TheHub work on layer 1 i.e. Physical layer of OSI Model
In which layer of osi model dose repeater works?
It depends on what kind of model it is, but in the model for computer 321O, it is on the layer between trhe keyboard and the behind screen, and there is a button with the osi code and there says everything.
In which layer cabling take place?
If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).
Which layer of the osi model covers cabling and electrical signaling?
First layer of the OSI model covers the cabling and electrical signaling. The first layer of OSI model is the physical layer. The physical layer also decides the transmission mode and physical media.
What layer of the OSI does the IEEE 802.22 standard work in?
All 802.x map to 1. Data Link 2. Physical layer in OSI model.
Which layer of OSI is responsible for modulation or demodulation?
physical layer
What layer does a router lie on?
Assuming you are using the OSI Modem a router sits on Layer 3: Network
What is the layer one of the OSI model?
The 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.
