10 Questions
What is the primary responsibility of the Session Layer in the OSI model?
Establishing and maintaining communication sessions between applications
Which protocol operating at the Transport Layer is known for providing reliable data transmission?
Transmission Control Protocol (TCP)
What is the primary function of the Network Layer in the OSI model?
Focusing on logical addressing, routing, and forwarding of data packets
Which layer of the OSI model is responsible for defining the electrical, mechanical, and procedural aspects of network connections?
Physical Layer
What is the purpose of data encapsulation in the OSI model?
To add headers and trailers to data received from the upper layer, forming Protocol Data Units (PDUs)
Which statement about the OSI model is correct?
It is a conceptual framework designed to facilitate communication between devices and hosts using different platforms.
How are the layers of the OSI model categorized?
The upper layers handle application-related interactions, while the lower layers manage data transmission processes.
What is the primary function of the Application Layer in the OSI model?
It mediates communication between user applications and the underlying network.
Which of the following protocols operates at the Presentation Layer of the OSI model?
Data compression and encryption protocols
Why is comprehending the principles of the OSI model important, despite its rare direct application in modern systems?
It serves as a foundational reference for comparing and understanding other networking models, notably the TCP/IP model.
Learn about the OSI (Open Systems Interconnection) model, a conceptual framework for communication between devices and hosts across different platforms. Understanding its principles is key for comparing networking models like the TCP/IP model. The OSI model consists of seven layers that simplify communication tasks.
