Medium Access Control (MAC)
Medium Access Control (MAC) is a sublayer of the Data Link Layer in the OSI model. It plays a critical role in managing how devices in a shared network environment access the communication medium. The MAC sublayer ensures efficient and collision-free transmission of data over both wired and wireless networks. Functions of the MAC Sublayer…

Data Link Layer : OSI Model
The Data Link Layer (Layer 2 of the OSI model) is a critical intermediary responsible for node-to-node communication within the same network segment. By managing data framing, addressing, and error detection, it ensures that data packets are reliably transmitted across physical links, providing a bridge between the Physical Layer and the Network Layer. Core Responsibilities…
