The physical layer is layer 1. It comprises the hardware (routers, repeaters, hubs, switches, etc.) that are used to form the physical basis of a network. They receive, process, and transmit raw electric (or optical) signals, rather than logical data packets.

Explain OSI model?
The Open Systems Interconnection model (OSI model) was a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a way of sub-dividing a communications system into smaller parts called layers. Similar communication functions are grouped into logical layers. A layer provides services to its upper layer while receiving services from the layer below. On each layer, an instance provides service to the instances at the layer above and requests service from the layer below.For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.
Do scientific models have two basic types?
mathematical model and physical model
Types of scientific models?
They are: 1. Conceptual-such as our mental image of the DNA spiral, helps frame research questions and make general predictions 2. Numerical-uses math or statistics to describe the image and make quantitative predictions about it 3. Physical-physically represents the object and it's apprearance
What type of models in science can be seen and touched?
Physical Model
What does model mean science term?
A model is a physical three dimensional object that is created too appear as an object which is usually too small or large.
What is the physical layer of the OSI model designed to do?
hub work at physical layer of osi model
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 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.
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.
What is the position of the transmission media in the OSI model or the internet model?
it comes in the first layer, or popularly known as the physical layer. must not be confused to be in datalink layer.
You want to use the OSI reference model to troubleshoot a repeater Which OSI layer will you focus on?
Repeaters operate at the physical layer of the OSI model.
Which layer ARE RJ45 connectoroperate in osi model?
1. Physical layer
What layer of osi model is modem work?
physical layer Layer 1
What layer of the OSI model routes data different lLANs and WANs based on network addresses?
Physical Layer of OSI model
Which OSI model layer is responsible for transmission?
