Layer 2 Networking

Layer 2 networking, also known as the data link layer, is responsible for transferring data between devices on the same local network (like in a home or office). It manages how devices identify each other using MAC addresses, ensures data is delivered to the correct device, and handles error detection to keep communication reliable. Think of it as a local delivery service within a neighborhood, ensuring packages (data) reach the right house (device) efficiently and accurately. It operates behind the scenes, enabling devices to communicate smoothly without concern for the broader internet infrastructure.
