The technique of stalling (or inserting a bubble) in a pipeline is primarily used to resolve what type of issue?
Stalling is a simple, fundamental way to handle pipeline hazards. It involves inserting one or more "bubbles" (No-Operation or NOP instructions) into the pipeline. This effectively pauses the instructions behind the hazard, giving the instruction causing the issue enough time to complete its task, make data available (for a Data Hazard), or free up a required resource (for a Structural Hazard).
