Study Notes
TCP/IP Transport Layer
- User Datagram Protocol (UDP) offers a connectionless service that is end-to-end and transaction-oriented, emphasizing best-effort delivery.
TCP/IP Internetwork Layer Functions
- Provides a global addressing structure to ensure data can be routed across different networks.
- Manages service type requests that support various data transmission needs and requirements.
- Facilitates end-to-end data stream services for reliable communication between applications over a network.
TCP/IP Model vs. OSI Model
- The Application Layer of the TCP/IP model corresponds to the Application, Session, and Presentation Layers of the OSI reference model.
Email Communication Flow
- At the Transport Layer, data streams are fragmented into pieces, then passed to the Internetwork Layer.
- The Internetwork Layer appends source and destination IP addresses to packets and forwards them.
- The Network Interface Layer constructs frames from packets and converts them to bits for transferring across the physical medium.
Components of TCP/IP Internetwork Layer
- Includes protocols such as Internet Group Management Protocol (IGMP), Internet Protocol (IP), and Address Resolution Protocol (ARP).
Telnet Protocol
- Operates at the Application layer of the TCP/IP model, providing a text-based interface for remote communication.
TCP/IP Network Interface Layer Mapping
- Maps to both the Physical Layer and the Data Link Layer of the OSI reference model, supporting data transmission methods.
Internet Control Message Protocol (ICMP)
- Offers troubleshooting utilities like ping and traceroute to diagnose network issues.
Network News Transfer Protocol (NNTP)
- An application layer protocol that enables companies to publicly post and distribute information over the Internet.
Transmission Control Protocol (TCP) Reliability Mechanisms
- Employs checksums to verify data integrity, acknowledgments to confirm receipt of data, and sequence numbers to maintain the order of packets during transmission.
