What are the functions of the different layers of the OSI model?
Understand the Problem
The question is asking for information about the OSI model and its layers, outlining the purpose of each layer in a communication network.
Answer
The functions of the OSI model layers are: Physical - Moving bits; Data Link - Moving frames; Network - Delivering packets; Transport - Ensuring process-to-process delivery; Session - Managing sessions; Presentation - Syntax/semantics translation; Application - Providing user services.
The functions of the OSI model layers are: Physical Layer - Responsible for moving individual bits from one device to the next device; Data Link Layer - Responsible for moving frame from one hop to the next hop; Network Layer - Responsible for delivery of individual packet from source to destination; Transport Layer - Responsible for process to process delivery; Session Layer - Establish, maintain, synchronize, and terminate the interaction between sender and receiver; Presentation Layer - Takes care of syntax and semantics of the information exchange between two communication systems; Application Layer - Responsible for providing services to the user.

More Information
The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and implement layered network protocols. Each layer serves a distinct function, allowing systematic troubleshooting and development of networking equipment and protocols. The OSI model helps in standardizing network communication and interoperability between different systems and devices.
Tips
A common mistake is confusing the functions of adjacent layers, especially between the Transport and Network layers or the Presentation and Application layers.
