The skin consists of two primary layers: the epidermis and the dermis. The epidermis is the outer layer that provides a protective barrier against environmental factors, such as pathogens and UV radiation, and is responsible for the skin's pigmentation. Beneath it, the dermis contains connective tissue, blood vessels, and nerves, playing a crucial role in providing structural support, regulating temperature, and allowing sensation through its nerve endings. Together, these layers work to protect the body and maintain overall skin health.

The skin has two distinct layers. The outer layer is the epidermis. The epidermis is comprised of five layers. The inner layer is the dermis. The dermis is anchored to a subcutaneous layer, but it is not considered part of the skin.
The conditions that affect all layers of the skin are vast. Two conditions are cancer and deep burns on the skin.

Protocols at each of the OSI layers govern how they are to talk to each other. Each layer of the OSI model has different responsibilities and they may have multiple protocols that they could use. The sender and receiver in networks must agree on a common ground for communication, which is the protocol. Depending on what you are trying to accomplish there are different protocols at different layers of the OSI model. Basically, you need the two systems to agree on how to do that. That is the role of a protocol.
