Protokollatason

Protokollatason is a term that refers to the lowest level of communication protocols within a network stack. These protocols are responsible for the fundamental tasks of transmitting raw data bits across a physical medium. Examples of protokollatason protocols include Ethernet and Wi-Fi, which handle the physical addressing and transmission of data frames. They define how data is encoded into electrical signals or radio waves and how these signals are sent and received. Error detection at this level is typically limited to basic checks to ensure data integrity during transmission. The protokollatason operates directly above the physical layer and provides services to the network layer above it. Its primary function is to ensure that data can be reliably moved from one device to another over a local network segment. Without these foundational protocols, higher-level communication like internet browsing or email would not be possible. The specifics of how data is formatted into frames, the addressing schemes used, and the methods for collision detection (in older technologies) are all defined at this protokollatason.
