Connection-oriented services use acknowledgement mechanisms and flow control mechanisms to create reliable sessions. It is more reliable than connectionless network services2.6 Written Experimentrequires more overhead. Connectionless services do not provide an acknowledgement or flow control mechanism when sending data, and sessions are unreliable.Define the layers of OSI, understand the function of each layer, and describe how devices and network protocols are mapped to each layer. Be sure to remember the 7 layers of the OSI model and what functionality each layer provides. The application, representation, and session layers are the higher layers and are responsible for communication between the user interface and the application. The transport layer provides segmentation, sequencing, and virtual links. The network layer provides logical network addressing and routing in the interconnected network. The data link layer is responsible for encapsulating frames and for placing data on the network medium. The physical layer is responsible for transmitting the 1's and 0's and encoding them as digital signals for transmission over the network segments.In this section, you need to complete the following exercises to ensure that you fully understand the knowledge and concepts introduced in this chapter. Experiment 2.1: OSI Problems Experiment 2.2: Defining OSI Layers and Devices Experiment 2.3: Identifying Conflict Domains and Broadcast Domains Appendix A gives the answers.2.6.1 Written Test Experiment 2.1: OSI QuestionsAnswer the following questions about the OSI model. 1. which layer of functionality is described below: selecting and determining the availability of communication peers, establishing the connection requiredresources, coordinating the applications of the communicating parties, and forming a unified process for controlling data integrity and error recovery? 2. Which layer is responsible for converting data packets at the data link layer into electrical signals? Which layer is responsible for routing, enabling connections, and path selection between two end systems? 4. which layer defines the format, presentation, encoding, and conversion of data to a network-applicableWhich layer defines the format, presentation, encoding, and conversion to a network-ready format? Which layer is responsible for creating, managing, and terminating sessions between applications? 6. Which layer ensures reliable transmission of data as it traverses physical links and is primarily concerned with physical addressing, line rules, network topology, and network management?line rules, network topology, error notification, sequential delivery of data frames, and flow control? 7. which layer is used to enable reliable communication between end nodes through the network and to provide mechanisms for establishing, maintaining, and terminating virtual links; providing transmission error detection and recovery; and providing information flow control? 8. which layer provides logical addressing so that routers can be used to make path selections?
