Study Notes
Service Primitives
- Six service primitives exist to facilitate connection-oriented services in computer networks.
- Acknowledged datagrams are utilized for interaction between clients and servers.
Relationship of Services to Protocols
- Services operate independently and do not dictate how data is transferred; protocols govern the methods used to achieve these services.
Reference Models
- OSI (Open Systems Interconnection) and TCP/IP (Transmission Control Protocol/Internet Protocol) reference models serve as foundational structures in networking.
- Each model comprises specific layers to improve functionality and abstraction in networking operations.
- Comparisons reveal strengths and weaknesses between OSI and TCP/IP models.
OSI Reference Model
- Composed of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
- Each layer is designed for distinct functionalities, aiming to minimize information flow between layers.
- International standards influence the development of layers.
TCP/IP Reference Model
- Consists of four layers: Link, Internet, Transport, and Application.
- Protocols relevant to the TCP/IP model are studied within the context of these layers.
Comparison of OSI and TCP/IP Models
- Central concepts in the OSI model include services, interfaces, and protocols.
- Each model differs in structure and flexibility.
Critique of OSI Model and Protocols
- Criticisms of the OSI model include poor timing, outdated technology, ineffective implementations, and political issues.
Example Networks
- Significant networks include the Internet, ARPANET, NSFNET, third-generation mobile phone networks, Wireless LANs (802.11), RFID, and sensor networks.
ARPANET Development
- Initially designed from the telephone system structure; the design proposed a distributed switching system.
- The ARPANET experienced growth from December 1969 through September 1972, marking significant milestones in networking evolution.
NSFNET
- In 1988, NSFNET served as a major backbone for network connectivity, reinforcing the reach of interconnections.
Key Terms in Networking
- Important terms include packets (small data units), packet switching (data transmission method), routing (determining data paths), datagrams (self-contained data packets), and virtual circuits (logical connections between nodes).
Network Software
- Involves protocol hierarchies and the design issues tied to different service types, focusing on the distinction between connection-oriented and connectionless services.
- The relationship between service primitives and network protocols is crucial for establishing efficient communication routes.

Description
This quiz covers the concept of service primitives in computer networks as detailed in the fifth edition of Andrew Tanenbaum's book. It discusses the six service primitives that facilitate a connection-oriented service and includes examples of client-server interactions. Test your understanding of these fundamental networking concepts.
