The Open Systems Interconnection (OSI) model defines a networking framework to implement protocols in layers, with control passed from one layer to the next. It is primarily used today as a teaching tool. It conceptually divides computer network architecture into 7 layers in a logical progression.

Keep in mind that while certain technologies, like protocols, may logically “belong to” one layer more than another, not all technologies fit neatly into a single layer in the OSI model. For example, Ethernet, 802.11 (Wifi) and the Address Resolution Protocol (ARP) procedure operate on >1 layer. The OSI is a model and a tool, not a set of rules. OSI Layer 1. Layer 1 is the physical layer. Ethernet works at layer two and defines CSMA/CD. The OSI (Open System Interconnection) Model breaks the various aspects of a computer network into seven distinct layers.

Each successive layer envelops the layer beneath it, hiding its details from the levels above. The OSI Model isn’t itself a networking standard in the same sense that Ethernet and TCP/IP are. Ethernet works at layer two and defines CSMA/CD. This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model. This list is not exclusive to only the OSI protocol family.

POWERLINK is based on the ISO/OSI layer model and supports client/server and it could also be based on faster Ethernet variants (such as Gbit Ethernet).

It is working directly with the hardware, sending and receiving signals through the Network Interface. The OSI reference model organizes a network into seven layers (a protocol stack) . These layers define how networking hardware and software are to hand data  OSI stands for open systems interconnection.
