What is the main purpose of using frame fragmentation?

The main purpose of using frame fragmentation is to ensure compatibility with devices that have a lower Maximum Transmission Unit (MTU). When sending data across a network, each frame must adhere to the MTU size limits imposed by various networking devices along the transmission path. If a frame is larger than the MTU supported by a device, it cannot be transmitted normally, which could lead to dropped packets and connectivity issues.

By fragmenting larger frames into smaller ones, each piece can be transmitted without exceeding the MTU limitation. This process allows for effective communication between devices that may operate with differing MTU sizes, ensuring that data can flow smoothly across diverse segments of the network. This compatibility is crucial for maintaining stable network operations and preventing data loss due to size mismatches.

In contrast, while extreme traffic conditions may require careful management of data flow, fragmentation primarily addresses the size constraints set by MTUs rather than avoiding data loss due to congestion. Similarly, although enhancing transmission speed and improving data security are important considerations in networking, they are not the primary objectives of frame fragmentation itself. Thus, the use of frame fragmentation serves the core function of adapting data to fit the limitations of the network infrastructure.
