This layer also introduces MAC addressing, enabling devices to identify each other on the same network segment. 11 standards for wireless communication, and protocols governing fiber optics and serial links like RS-232.
OSI Protocols by Layer Presentation Layer: IP, TCP, and Key Standards
11 for wireless operate here, along with Point-to-Point Protocol (PPP) for direct connections. This allows a single device to handle multiple conversations simultaneously without confusion.
Firewalls and network address translation (NAT) also operate at this layer, adding security and flexibility to address management. This layer ensures data can traverse multiple hops to reach its destination globally.
OSI Protocols by Layer Presentation Layer: Standards, Security, and IP addressing
Internet Protocol (IP) is the central protocol here, providing unique addresses and enabling devices to communicate across different networks. They also regulate data flow to prevent faster senders from overwhelming slower receivers.
