Question: What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?

Option a: Flow control. This choice describes a mechanism where the sender slows down or pauses transmission based on the receiver's ability to process data, preventing buffer overflow and packet loss when data arrives faster than it can be consumed. It directly addresses the problem of data being sent too quickly.

Option b: Encapsulation. Encapsulation wraps data with protocol-specific headers and trailers for transmission, but it does not by itself regulate the sending rate or prevent overloading the network buffers. It’s about formatting data, not flow regulation.

Option c: Access Method. In networking, access methods (e.g., CSMA/CD, time-division access) control how multiple devices share a shared medium, but they are more about contention and medium access in a multi-user environment rather than directly preventing drops due to sender rate. This can influence performance but isn’t specifically a mechanism to throttle the sending rate between two computers.

Option d: Sequence control. Sequence control ensures packets are delivered in order, preserving data integrity, but it does not address the issue of sending data too quickly. Packets could still be dropped due to overflow even if their order is preserved.

Summary: The concept that directly mitigates dropping packets from excessive send rate is flow control, which coordinates speed between sender and receiver to match processing capability and buffering. The other options describe related but different concerns: data formatting, medium access, and order integrity rather than rate regulation.
