Difference between Cable modem and Physical layer

Cable modem vs. Physical layer

A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fibre-coaxial (HFC) and radio frequency over glass (RFoG) infrastructure. In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer.

Similarities between Cable modem and Physical layer

Cable modem and Physical layer have 21 things in common (in Unionpedia): Bandwidth (signal processing), Bit rate, Communication channel, Data link layer, Digital subscriber line, Ethernet over twisted pair, Institute of Electrical and Electronics Engineers, International Telecommunication Union, Line code, Local area network, Medium access control, Modulation, Network interface controller, Network topology, OSI model, PHY (chip), Signal, Signal-to-noise ratio, Simplex communication, 10BASE2, 10BASE5.

Bandwidth (signal processing)

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.

Bit rate

In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time.

Line code

Some signals are more prone to error than others when conveyed over a communication channel as the physics of the communication or storage medium constrains the repertoire of signals that can be used reliably.

Local area network

A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.

Medium access control

In IEEE 802 LAN/MAN standards, the medium access control (MAC) sublayer (also known as the media access control sublayer) and the logical link control (LLC) sublayer together make up the data link layer.
