OSI vs TCP/IP comparison in Computer Networks - Quick Revision & Key Differences

Recall & Review

beginner

What does OSI stand for in networking?

OSI stands for Open Systems Interconnection. It is a model used to understand and design how different computer systems communicate over a network.

beginner

How many layers does the OSI model have?

The OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

beginner

How many layers does the TCP/IP model have?

The TCP/IP model has 4 layers: Network Interface, Internet, Transport, and Application.

intermediate

Which model is more theoretical and which is more practical: OSI or TCP/IP?

The OSI model is more theoretical and used as a teaching tool, while the TCP/IP model is more practical and used in real-world internet communications.

intermediate

Name one key difference between the OSI and TCP/IP models.

One key difference is that OSI has 7 layers and separates the Session and Presentation layers, while TCP/IP combines these functions into its Application layer and has only 4 layers.

How many layers does the OSI model have?

A 5

B 4

C 3

D 7

The OSI model has 7 layers, which helps to understand network communication in detail.

Which model is used as the basis for the internet protocols?

A OSI

B TCP/IP

C Both equally

D None

The TCP/IP model is the foundation for internet protocols and real-world networking.

Which OSI layer is responsible for routing data between networks?

A Network

B Transport

C Data Link

D Physical

The Network layer handles routing data between different networks.

In TCP/IP, which layer combines the functions of OSI's Session and Presentation layers?

A Internet

B Transport

C Application

D Network Interface

The Application layer in TCP/IP handles what OSI separates into Session and Presentation layers.

Which model is considered more theoretical and used mainly for teaching?

A OSI

B Neither

C Both

D TCP/IP

The OSI model is more theoretical and is often used to teach networking concepts.

Explain the main differences between the OSI and TCP/IP models.

Think about layers and real-world use.

Describe the purpose of the OSI model in networking.

Focus on why the OSI model exists.
