This document discusses the Transport layer and protocols TCP and UDP. It explains that the Transport layer supports reliable communication across networks by implementing protocols that handle segmentation, reassembly, and reliability. TCP provides reliable, ordered delivery using sequence numbers, acknowledgements, and retransmissions to handle lost data. UDP is simpler and does not guarantee delivery, making it better for streaming media. Port numbers are used to direct segments to the proper application process on servers or clients.

This document compares the OSI model and TCP/IP model. The OSI model has 7 layers - physical, data link, network, transport, session, presentation, and application layer. The TCP/IP model has 4 layers - network access, internet, transport, and application layer. The OSI model is a generic standard while TCP/IP is its implementation for internet. Key differences are that OSI has strict layering and reliably delivers all packets, while TCP/IP has loose layering and TCP reliably delivers packets while IP does not.

Mid term Topic

Data communication involves the transfer of data between a source and receiver. It focuses on how the data is transferred and preserved during transmission. There are five main components: a message, sender, receiver, medium, and protocol. The TCP/IP model defines four layers - application, transport, internet, and network interface - that work together to transmit data across networks. The transport layer ensures reliable and error-free delivery of data between processes running on different devices. It includes protocols like TCP that provide features like flow control, error checking, and retransmission. Data modulation converts analog and digital signals so they can be transmitted over different mediums. Common analog modulation techniques are amplitude, frequency, and phase modulation, which vary

Data communication involves the transfer of data between devices using specific elements: a message, sender, receiver, transmission medium, and protocol. There are two main methods for data transmission - parallel transmission which sends multiple bits simultaneously through separate paths, and serial transmission which sends bits one after another as a sequential stream. The basic functions and processes of computers are also important for understanding how data communication works at a fundamental level.

This document discusses network models and addressing in computer networks. It describes the OSI 7-layer model and compares it to the TCP/IP protocol suite. Each layer of the OSI model has specific duties, such as physical addressing at the data link layer and logical addressing at the network layer. TCP/IP protocols map to these layers, with IP at the network layer handling logical addressing. There are four levels of addressing in TCP/IP: physical, logical, port, and specific addresses that relate to different layers and allow identification of devices, networks, applications and resources on the network.

Tcp

This document discusses the TCP/IP protocol and its layers. It compares TCP/IP, which has 4 layers (application, transport, network, physical), to the OSI model which has 7 layers. The application layer handles process communication across networks. The transport layer includes TCP which originated with the initial internet protocol. The network layer routes packets between devices. The physical layer deals with bit-level transmission and physical connections.

The OSI model defines a standard framework for how applications can communicate over a network through 7 layers of abstraction: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer has a specific purpose and set of protocols to convert data between layers, establish connections, route packets, ensure reliable and secure delivery of data, and interface with applications. The layers work together to take a message from an application, convert it to bits for transmission over a physical medium, and reconstruct it back to a message at the destination.

PPP defines frame formats, encapsulation, link establishment, optional authentication, and network layer protocol multiplexing. It uses the Link Control Protocol for link configuration, establishment, and testing. Authentication Protocols like PAP and CHAP can authenticate users. Network Control Protocols allow different network layer protocols to be configured and data to be exchanged over the link. PPP supports connections over various links and network address assignment.

The document discusses network reference models and the OSI and TCP/IP models. It provides details on each layer of the OSI model and its functions. The key points are that reference models divide network communication into simpler components, provide standardization, and prevent changes in one layer from affecting others. The OSI model has 7 layers and separates network functions into upper layers for applications and lower layers for data transmission. The TCP/IP model is based on widely used TCP and IP protocols.

This document provides an overview of key concepts in network technology, including: 1) The basic elements of communication include a message source, channel, and destination. A network allows data to be sent across interconnected devices. 2) Data is sent in segments, and networks have hardware, software, and end devices that interface with users or act as clients, servers, or both. Intermediary devices provide connectivity across the network. 3) Local area networks connect devices within a home or building, while wide area networks connect LANs over longer distances using the Internet. Protocols allow successful communication over networks by establishing rules. 4) Models like TCP/IP and OSI provide layered approaches to network design and the communication

OSI Network Layer

OSI Network Layer

The document discusses the network layer in the OSI model. It describes the key responsibilities of the network layer, including addressing, routing data between end devices, and allowing communication between different networks. The most common network layer protocol is the Internet Protocol (IP), which uses addresses and best-effort delivery to route packets to their destinations. IP packets contain source and destination addresses, and may be routed through multiple networks using hierarchical addressing schemes, routers, and routing tables maintained by routing protocols. Network testing tools like ping and traceroute allow engineers to diagnose connectivity issues.

- The document discusses Open Shortest Path First (OSPF) configuration for a network comprising routers and PCs partitioned into 4 areas. - An addressing scheme is proposed using /30 subnet masking to assign point-to-point interfaces between routers in areas 120, 120, and 120. Area 99 is an OSPF multi-access network requiring a different approach. - OSPF is configured on the network with areas and interfaces assigned addresses according to the proposed scheme. A virtual link is also specified to connect the non-contiguous areas as required.

This document describes troubleshooting three network connectivity problems at OCP Enterprises. Problem 1 was that PC1 could not reach PC4, which was caused by R2 missing a route to network 1 in its routing table. Problem 2, that PC1 could not reach devices on network 3, was also due to this missing route. Problem 3, that only PC1 and PC3 but not PC2 could reach network 3, was found to be due to PC2 having an incorrect default gateway and IP address configuration.
