TCP/IP 5 Layer Model

1 - Physical Layer

The physical layer is the transceiver that drives the signals on the network

Transmits and receives bits

2 - Data Link Layer (MAC)

The Data Link Layer is responsible for creating the frames that move across the network

Transfers frames with physical (MAC) address

3 - Network Layer (IP)

The Network layer is responsible for creating the packets that move across the network

Transfers packets with virtual (IP) addresses

4 - Transport Layer

The Transport layer establishes the connection between applications on different hosts

Establishes connections with the remote host

5 - Application Layer

The Application layer is the group of applications requiring network communications

Generates the data and requests connections
