Discuss OSI and TCP layers. The Network Layering Model: OSI and TCP

The Network Layering Model: OSI & TCP

Open Systems Interconnection is (OSI), and Transmission Control Protocol(TCP) are both popular communication models for networking. OSI is a framework with seven layers that separates network operations and has specific rules and protocols. The Application layer gives users access to network resources. While the OSI model’s upper layers provide rules to enable communication, the OSI model’s lower layers deal with connecting physical devices. TCP is the TCP layer in the TCP/IP model. It is responsible for reliable Internet communication. The TCP layer ensures data transfer is accurate and complete by using ACKs and segmentation.   The OSI layer is usually used for the concept of the network, while TCP layers are used in actual implementation. To ensure reliable and secure communication, all applications connecting to network resources need to adhere to the OSI model’s rules. “OSI and TCP are often interdependent in their communication applied in networking” (Arocho, 2019). To put it another way, in order for TCP to function effectively, all layers within the OSI model need to be functioning correctly. Additionally, “the TCP layer is responsible for reassembling and delivering this data safely and securely to the upper layers of the OSI model” (Kurosh, 2021).   The OSI and TCP layers are important for managing data and transmitting it over the Internet.  References   Arocho, C.
