The document discusses various networking standards organizations and the OSI model. It describes organizations that set standards like ANSI, IEEE, ISO, IETF, and ICANN. It then explains the seven-layer OSI model and provides a brief overview of the functions of each layer, from the physical layer dealing with signals and voltages, to the application layer that applications use.
OSI MODEL
The OSI model is a reference model developed by ISO in 1984 for communication across different networks and applications. It defines the communication process into 7 layers, with layers 7 through 4 dealing with end-to-end communication and layers 3 through 1 dealing with communication between network devices. The 7 layers are: layer 7 application layer, layer 6 presentation layer, layer 5 session layer, layer 4 transport layer, layer 3 network layer, layer 2 data link layer, and layer 1 physical layer. Each layer has a specific function in the communication process.
Osi model
The OSI model defines 7 layers of standards for networking and operating systems involved in networking functions. The 7 layers are: application, presentation, session, transport, network, data link, and physical. Each layer has a specific role, with the highest layers dealing with application and user issues and lower layers dealing with physical network connections and transmission of raw data.

Finally, it covers topics like IP addressing classes, MAC addresses, and their purposes in network communication.
class 3
The document discusses the OSI and TCP/IP models for network communication.
The OSI model has 7 layers - physical, data link, network, transport, session, presentation, and application layer. Each layer has a specific function in the flow of data from source to destination.
The TCP/IP model is simpler and combines some OSI layers. It has 4 layers - network access, internet, transport, and application.
The OSI model helps networking professionals understand information flow and determine hardware/software needs to build computer networks.
OSI LAYERS
The OSI model divides network communication into 7 layers, with each layer responsible for specific functions. The physical layer is responsible for binary transmission and low-level details like establishing connections between nodes. Moving up, the data link layer handles framing and addressing at the hardware level. Above this, the network layer focuses on logical addressing, routing between networks, and congestion handling.

Chapter02 -- networking standards and the osi model
The document discusses networking standards organizations and the OSI model. It describes the seven layers of the OSI model and their functions. The layers are application, presentation, session, transport, network, data link, and physical. Data moves down through the layers of one system and up through the layers of the receiving system. Standards organizations like IEEE, ISO, and IETF help establish networking standards and protocols.
Network Fundamentals: OSI Model
The OSI reference model defines a 7-layer framework for how information from an application is transmitted across a network. It specifies that data moves from the application layer, through various layers that prepare and transmit the data, to the physical layer which transmits signals across a medium. The layers include application, presentation, session, transport, network, data link, and physical. Protocols like TCP/IP map to these layers to enable communication between devices.
OSI Model - Open Systems Interconnection
The Open Systems Interconnection (OSI) reference model has served as the most basic elements of computer networking since the inception in 1984. The OSI Reference Model is based on a proposal developed by the International Standards Organization (ISO).
Osi model
ISO is an organization which is established in 1947.
AN ISO standard that covers all aspects of network communication.
Network communication model is defined in OSI.
It was first introduced in the late 1970s, 1983
Network fundamentals
The International Standard Organization was developed a well-defined model for Communication Systems known as Open System Interconnection, or the OSI Model in the late 1970s. This layered model is a conceptualized view of how one system should communicate with the other, using various protocols defined in each layer. Further, each layer is designated to a well-defined part of communication system. For example, the Physical layer defines all the components of physical nature, i.e. wires, frequencies, pulse codes, voltage transmission etc. of a communication system.
TCP/IP means Transmission Control Protocol and Internet Protocol. It is the network model used in the current Internet architecture as well. Protocols are set of rules which govern every possible communication over a network. These protocols describe the movement of data between the source and destination or the internet. These protocols offer simple naming and addressing schemes.

: Instead of serving as protocol, the OSI model has become a teaching tool that shows how different tasks within a network should be handled in order to promote error-free data transmission.
An Introduction to the OSI ModelSource: Flickr/jonjohnson
The open system interconnection model, better known as the OSI model, is a network map that was originally developed as a universal standard for creating networks. But instead of serving as a model with agreed-upon protocols that would be used worldwide, the OSI model has become a teaching tool that shows how different tasks within a network should be handled in order to promote error-free data transmission.
These jobs are split into seven layers, each of which depends on the function’s “handed-off” from other layers. As a result, the OSI model also provides a guide for troubleshooting network problems by tracking them down to a specific layer. Here we’ll take a look at the layers of the OSI model and what functions they perform within a network.

The OSI model has 7 layers - physical, data link, network, transport, session, presentation and application. The TCP/IP model combines some of these layers and has 5 layers - physical, data link, network, transport and application. Each layer is responsible for distinct networking functions and passes messages to the adjacent layers for delivery. [/SUMMARY]

The document describes the OSI model and TCP/IP model. It explains:
- The OSI model has 7 layers (physical, data link, network, transport, session, presentation, application) while TCP/IP has 4 layers (network interface, internet, transport, application).
- The transport layer in TCP/IP includes TCP and UDP protocols which handle segmentation and reassembly of data.
- The network layer adds headers to data segments and handles addressing and routing between hosts using IP addresses.
- The data link and physical layers in OSI correspond to the network interface layer in TCP/IP, which deals with framing data and transmitting bits.
PC 106 PPT-06
The document discusses the OSI model, which defines 7 layers for network communication: Physical, Data Link, Network, Transport, Session, Presentation, and Application. It was developed by ISO to standardize network architectures and allow components from different vendors to communicate. Each layer has a set of well-defined functions and builds upon the layers below it, with standards developed independently for easier introduction and less effect of changes on other layers. This model divides network communication into simpler components and encourages standardization.

- 2. • The OSI reference model • Services in the OSI model Topics
- 3. • OSI Reference Model - internationally standardised network architecture. • OSI = Open Systems Interconnection: deals with open systems, i.e. systems open for communications with other systems. • Specified in ISO 7498. • Model has 7 layers. OSI Reference Model
- 4. • Layers 1-4 relate to communications technology. • Layers 5-7 relate to user applications. 7-Layer OSI Model Layer 7 Layer 6 Layer 5 Layer 4 Layer 3 Layer 2 Layer 1 Application Layer Presentation Layer Session Layer Transport Layer Network Layer Data Link Layer Physical Layer Communications subnet boundary
- 5. • Level at which applications access network services. – Represents services that directly support software applications for file transfers, database access, and electronic mail etc. Layer 7: Application Layer
- 6. • Related to representation of transmitted data – Translates different data representations from the Application layer into uniform standard format • Providing services for secure efficient data transmission – e.g. data encryption, and data compression. Layer 6: Presentation Layer
- 7. • Allows two applications on different computers to establish, use, and end a session. – e.g. file transfer, remote login • Establishes dialog control – Regulates which side transmits, plus when and how long it transmits. • Performs token management and synchronization. Layer 5: Session Layer
- 8. • Manages transmission packets – Repackages long messages when necessary into small packets for transmission – Reassembles packets in correct order to get the original message. • Handles error recognition and recovery. – Transport layer at receiving acknowledges packet delivery. – Resends missing packets Layer 4: Transport Layer
- 9. • Manages addressing/routing of data within the subnet – Addresses messages and translates logical addresses and names into physical addresses. – Determines the route from the source to the destination computer – Manages traffic problems, such as switching, routing, and controlling the congestion of data packets. • Routing can be: – Based on static tables – determined at start of each session – Individually determined for each packet, reflecting the current network load. Layer 3: Network Layer
- 10. Packages raw bits from the Physical layer into frames (logical, structured packets for data). Provides reliable transmission of frames It waits for an acknowledgment from the receiving computer. Retransmits frames for which acknowledgement not received Layer 2: Data Link Layer
- 11. • Transmits bits from one computer to another • Regulates the transmission of a stream of bits over a physical medium. • Defines how the cable is attached to the network adapter and what transmission technique is used to send data over the cable. Deals with issues like – The definition of 0 and 1, e.g. how many volts represents a 1, and how long a bit lasts? – Whether the channel is simplex or duplex? – How many pins a connector has, and what the function of each pin is? Layer 1: Physical Layer
- 12. • Explicit Presentation and session layers missing in Internet Protocols • Data Link and Network Layers redesigned Internet Protocols vs OSI Application Presentation Session Transport Network Data Link Physical Application TCP IP Network Interface Hardware
