Internally, the data transmission starts from the Application layer of one device and travels to the Physical layer while adding some information to the data packet. A bit is a binary digit, 0 or 1, that is a basic unit of communication in the Physical layer of the OSI model.ĭata is processed and transmitted from one device to another on a network. Frames contain information related to the flow control, frame synchronization, and error checking. On the other hand, the frame is a unit of data used in the Data-Link layer of the OSI model. The Network layer of the Open System Interconnection (OSI) model uses the packets as a data unit. A packet is a unit of data that is transmitted over the network, and contains routing information that helps it to reach its destination. The basic component of any network communication is data, which is in the form of packets, frames, or bits. In this blog, we will discuss the basic components of the 802.11 MAC architecture.
