✅ C'mon over to 🤍 where you can learn PLC programming faster and easier than you ever thought possible! = ✅ Check out the full blog post over at 🤍 = OSI stands for Open Systems Interconnection and is a conceptual framework for how applications communicate over a network. There are seven layers within the model and the depiction of the layers is used to help users identify what is happening within a networking system. The OSI model layers are typically described from the top layer down. The layers are described as Application, Presentation, Session, Transport, Network, Data Link, and Physical. These layers are provided by a mixture of network card drivers, operating systems, applications, and networking hardware that facilitate the transmission of signals over Ethernet, Fiber Optic, Wi-Fi, or other wireless protocols. We’ll describe the layers from the top down as the top layer is the Application layer or layer 7. This is the layer that most users interact with and will recognize. The Application layer provides network services to the end user. These services are protocols that work with the data the client is using. One of these protocols may be HTTP that is used with web browsers such as Google Chrome, Firefox, and Internet Explorer. Other examples of applications that use this layer are Office, Outlook, and Skype. All of those interactive applications provide a set of services that allow the application layer to supply data to and receive data from the Presentation layer. The Presentation layer, or layer 6, performs the uncomplicated task of syntax processing or converting data from one format to another. For example, say you are ordering something from an online store. These transactions are typically handled in a secure transmission which means that the data passing between the “store” or the Website Application will transmit encrypted data to the Presentation layer that will need to be decrypted and processed. This layer handles translating the data from the top layer, which is presented in the application format, to network format and vice versa. After the Presentation layer processes the data from one format to another, the information is then passed to the Session layer or the Application layer depending on whether the data is transmitting or receiving. = Missed our most recent videos?

Definition, Function, and use of the OSI network model. Protocols in computer network layers of OSI model. Notes : 🤍 Facebook : 🤍 OSI Model defines and is used to understand – How data is transferred from one computer to another in a computer network? In the most basic form, two computers (end-points) connected to each other with LAN Cable (Network Media) and connectors (RJ45) sharing data with the help of NICs forms a network. But if one computer is based on Microsoft Windows and the other one has MAC OS installed, then how these two computers are going to communicate with each other? In order to accomplish successful communication b/w computers or networks of different architectures, 7-layered OSI Model or Open System Interconnection Model was introduced by the International Organization for Standardization in 1984.

The OSI model (Open System Interconnect) is a theoretical stack of 7 layers that can be used as a reference to understand how a network operates. The model was introduced to standardize networks in a way that allowed multi-vendor systems, prior to this you would only be able to have a one vendor network as the devices could not communicate with other vendor devices. The Layers Application (layer 7) This layer is where the application and user communicates. Application specific protocols are used here such as SMTP (simple mail transfer protocol) for sending emails from Outlook. Presentation (layer 6) This layer formats the data in a way that the receiving application can understand it. This layer is also able to encrypt and decrypt date if needed. Session (layer 5) This layer is responsible for establishing and terminating of connections between devices. Transport (layer 4) The transport layer of OSI Model is used for error handling and sequencing to unsure no data is lost. This layer also adds source and destination port numbers Network (layer 3) The network layer handles IP address routing. At this stage of the OSI model the source and destination IP address is added to the data. Data Link (layer 2) At this layer the physical address (MAC Address) is added to the data, this includes the source and destination MAC address. Physical (layer 1) The physical layer is the lowest layer of the OSI model. Its key responsibility is to carry the data across the physical hardware such as an Ethernet cable to the destination. This video is designed to give a basic and general overview of the OSI model. Its aim is to simplify the concept to make it easier to understand. #ccna #cisco #networking

The Internet protocol suite is the conceptual model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP because the original protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). It is occasionally known as the Department of Defense (DoD) model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed and received. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.[1][2] From lowest to highest, the layers are the link layer, containing communication methods for data that remains within a single network segment (link); the internet layer, connecting independent networks, thus providing internetworking; the transport layer handling host-to-host communication; and the application layer, which provides process-to-process data exchange for applications. Technical standards specifying the Internet protocol suite and many of its constituent protocols are maintained by the Internet Engineering Task Force (IETF). The Internet protocol suite model is a simpler model developed prior to the OSI model.
Understanding the Open Systems Interconnection (OSI) Model is crucial for an IT career. Not only does it come up in several certification exams, but it can help you conceptualize how real-world applications work end-to-end. In this video, CBT Nuggets trainer Keith Barker (🤍KeithBarker) covers three important aspects of the OSI reference model: what is it, how does it work, and how can we use it?

The OSI model describes how a data transfers over the network from one computer to the other and the way that the systems send information to one another. In order to accomplish successful communication between computers, there are 7 distinct layers which are interconnected and which work closely to make the communication happen, that is why it is called the open system interconnection model or the OSI seven layer model or open system. The purpose of this model is to enable functionality and interoperability between different vendors and connectors. From a design point of view, it divides larger tasks into smaller, more manageable ones. The seven Layers of OSI model are Layer 1 - Physical Layer Layer 2 - Data Link Layer Layer 3 - Network Layer Layer 4- Transport Layer Layer 5- Session Layer Layer 6 - Presentation Layer Layer 7 - Application Layer #osimodel #tcp #osi #networklayer

More about this video - In this video, we will learn the fundamentals of the OSI model. Open System Interconnect (OSI) model is a framework that divides all network communication into 7 distinct layers. Each layer has a specific role to play in network communication. These 7 layers (from bottom to top) are: - 1. Physical 2. Data Link 3. Network 4. Transport 5. Session 6. Presentation 7. Application So in this video, we will learn the very basics of osi model using a real-life example and understand how a sender sends and the receiver receives the data via the network. Also, we will understand what are Protocol Data Units (PDUs) and how data changes while it flows through each layer of osi model. We will also know the famous protocols of each layer like http, ftp, smpt,tcp, udp,ip etc. We will come to know which device falls into which layer like routers, firewalls, VPNs, proxies, etc. At the end, we will learn the basic difference between osi and tcp/ip model. Hope this video gives you a new perspective of learning the osi model.

#osi #OSIModel #Networking Hello Friends, In this Video tutorial We will Learn OSI layers in a computer network Or computer network layers, We will try to understand OSI Model, OSI reference model or open system interconnection model or networking model including Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer and Physical layer. I will try to clear your concept regarding OSI Model Definition, Function, and use. Protocols in computer network layers of OSI model. OSI Model defines and is used to understand. How data is transferred from one computer to another in a computer network? In the most basic form, where two computers connected to each other with LAN Cable and RJ45 connectors sharing data with the help of Network Card forms a network. But if one computer is based on Microsoft Windows and the other one has MAC OS installed, then how these two computers are going to communicate with each other? In order to accomplish successful communication between computers or networks of different architectures, 7-layered OSI Model or Open System Interconnection Model was introduced by the International Organization for Standardization in 1984. OSI model contain Application Layer, Presentation Layer, Session Layer, Transport layer, Network Layer, Data Link Layer & Physical Layer. Open system interconnection model, osi model, what is osi model, explain osi model, osi model lecture, define osi model, osi model in networking, how data is transferred in internet, network security, osi reference model, osi model in hindi, osi 7 layers, 7 layers of osi model, osi stack, application layer, presentation layer, session layer, transport layer, network layer, data link layer, physical layer. what is osi model, osi model, osi layers, osi, OSI, 7 layers of osi model, network layer, osi network model, 7 layers of networking, osi reference model, ip layers, osi model layer, osi 7 layer, osi model explained, m osi, network layer, iso osi, ip layers, osi model, osi model explained, osi model animation, the osi model, osi model English, application layer in osi model,osi model troubleshooting, osi layers, osi model 7 layers, osi model 7 layers explained, presentation layer, presentation layer in osi model, session layer, session layer in osi model, transport layer, transport layer in osi model, transport layer protocols, network layer, network layer protocols, layers of osi model, layers of osi model explained, layers of osi model and their functions , Datalink layer, protocols, Physical layer, Application layer, open systems interconnection model, tcp, media access control, data link layer, network osi model, network layer in osi model, osi model has how many layers,
OSI Model animation is the most intuitive explanation of how the OSI model works and, when I was learning I found out that most of the videos that explained the OSI model are not so easy to understand, so that lead me to the creation of this video. All of OSI model layers, like the application layer, presentation layer, session layer, transport layer, network layer, data link layer, physical layer have defined input and outputs and that's why the internet is working so well Important Timestamps One Page Summary of entire Lecture 10:30 Airline Company Example 1:09 Pizza Company Example 1:35 King's Meeting 3:34 Side by Side Comparison of OSI and King's Meeting 6:40 Chaos Networking 3:07 Complete Timestamps: 0:00 Why this Video 0:12 Either Memorize or Understand the OSI 0:43 Introduction to OSI 0:56 Layered Architecture in networking 1:09 Airline Company Example 1:35 Pizza Company Example 2:24 Benefits of Layered Architecture in networks 3:07 Chaos Networking 3:17 Introduction to OSI Model 3:34 King's Meeting 3:40 King's Sender Side: Application Layer 3:53 King's Sender Side: Presentation Layer 4:17 King's Sender Side: Session Layer 4:41 King's Sender Side: Transport Layer 5:08 King's Sender Side: Network Layer 5:22 King's Sender Side: Data Link layer 5:32 King's Sender Side: Physical Layer 5:34 Intermediate Node: 5:58 King's Receiver Side: Transport Layer 6:09 King's Receiver Side: Session Layer 6:17 King's Receiver Side: Presentation Layer 6:26 King's Receiver Side: Application Layer King's example Complete Workflow [ Real Life example of OSI Model ] 6:40 Side by Side Comparison of OSI and King's Meeting 7:01 How Application Layer works? 7:40 How Presentation Layer works? 8:00 How Session Layer works? 8:19 How Transport Layer works? 8:49 How Network Layer works? 9:45 How Data Link Layer works? 10:09 How Physical Layer works? 10:30 One Page Summary of entire Lecture Open system interconnect was formalized by International Organization for standardization in 1984. It is a reference tool for understanding how the data is communicated between any two networked systems. Networking is complex so the OSI model divides the complex functions of computer networks into 7 different layers of OSI. So to easily understand the system. Sometimes the animations are required to understand and visualize the difficult concepts so this whiteboard animation video works well in explaining the working principle of the OSI Model. OSI Model will also help you inculcate the TCP/IP protocol, also called as transmission control protocol and Internet Protocol.
