1-3 INTRODUCTION TO TCP IP AND THE OSI MODEL Flashcards
Where did the OSI model come from?
The International Organization for Standardization (ISO), a multinational body dedicated to worldwide standardization.
What is the OSI Model?
Open Systems Interconnection Model
A conceptual framework used for standardizing the functions of telecommunication and computing systems.
What are the layers of the OSI Model?
Application Layer (L7) - handles the network services to end-user applications
Presentation Layer (L6) - Translates and encrypts data for the application layer
Session Layer (L5) - Manages sessions and dialogues between applications
Transport Layer (L4) - Ensures complete and reliable data transfer
Network Layer (L3) - Responsible for data routing, addressing, and packet forwarding
Data Link Layer (L2) - Manages node-to-node data transfer and error detection
Physical Layer (L1) - Handles the physical connection and raw data transmission.
What is the purpose of the OSI model?
The OSI model serves as a universal set of guidelines for ensuring interoperability among diverse networking products and software.
Where did TCP/IP come from?
Developed in the 1970s for the United States Department of Defense or DoD’s Advanced Research Projects Agency Network (ARPANET) project.
What is TCP/IP?
Transmission Control Protocol/ Internet Protocol, Also known as the TCP/IP suite and Internet Protocol Suite. A conceptual framework used for designing and implementing network communications protocols in networks. It consists of four layers.
What are the layers of the TCP/IP Model?
Application Layer (L4) - focused on user interfaces and higher-level protocols.
Transport Layer (L3) - responsible for end-to-end communication and data transfer management.
Internet Layer (L2) - handles routing and addressing of data packets for transmission across networks.
Network Interface Layer (L1) - focused on the network interface for data exchange over physical networks.
