The common technique used by processors to execute instructions while waiting for memory operations to complete is Pipelining.

Here's a step-by-step explanation:

1. Pipelining is a process in which the processor begins executing a second instruction before the first has been completed. That is, several instructions are in the pipeline simultaneously, each at a different processing stage.

2. The pipeline is divided into different stages and each stage completes a part of an instruction in parallel. The stages are connected one to the next to form a pipe - instructions enter at one end, progress through the stages, and exit at the other end.

3. Pipelining doesn't decrease the time it takes to complete an instruction; instead it increases the number of instructions that can be processed simultaneously and thus speeds up the processing rate.

4. This technique is used to improve the performance of the system and is more efficient than executing instructions sequentially.

5. Overclocking, Defragmentation, and Virtualization are not techniques used by processors to execute instructions while waiting for memory operations to complete. Overclocking is a technique to increase the operating speed of a component. Defragmentation is a process that reduces the amount of fragmentation in file systems. Virtualization is a technology that allows you to create multiple simulated environments from a single physical hardware system.
