Networking/Cybersecurity

1

Physical: Responsible for transmitting raw bitstreams over a physical medium

2

Data Link: Handles error detection and correction from the physical layer and controls how data is placed on the medium

3

Network: Determines the best physical path for data to reach its destination

4

Transport: Ensures complete data transfer with error checking and flow control

5

Session: Manages sessions or connections between applications

6

Presentation: Translates data between the application layer and the network

7

Application: Provides network services directly to user applications such as email
