A series of protocols that work together to transmit data from one computer, through any number of pieces of network hardware, to another computer
It is a concept; not a physical thing.
What are the 4 layers?
Application layer
Transport layer
Network layer
Data link layer
What is the Application layer?
Where network applications operate
What does the Transport layer do?
Establishes communication between the sender and the recipient, agreeing on how communication will take place
What does the Network layer do?
Packages data for transmission by breaking it into units called packets, which are sent across the network
Give a description of the Data layer (AKA Network Interface Layer)?
The physics components of computer, such as the network interface card (NIC), operate at this level
Name protocols on the Application layer:
HTTP HTTP FTP SMTP IMAP
Name protocols on the Transport layer:
TCP
UDP
Name protocols on the Network layer:
IP
Name protocols on the Network Interface layer:
