Study Notes

Physical Layer in OSI Model

Defines the physical means of transmitting data between devices, including cable specifications, wireless transmission, and network topology
Provides an interface to the data link layer

Functions of Physical Layer

Specifies the transmission mode (simplex, half-duplex, full-duplex)
Defines the type of cable or wireless medium used
Manages the transmission of raw bits over a physical medium
Establishes and terminates a connection to a physical medium
Provides mechanical, electrical, and functional specifications for interfaces and devices
Manages data transmission rates, encoding, and decoding

Non-Functions of Physical Layer

Does not perform framing, error detection, or correction (these are functions of the data link layer)

Network Topology Decisions

Helps in deciding whether to use a bus, star, or ring topology in a network

Transmission Definition

Defines the transmission of bits over the data link layer
