What does PGA stand for?

  1. Pin Graph Array

  2. Pin Grid Array

  3. Processor Grid Array

  4. Processor Graph Array

The correct answer is: Pin Grid Array

PGA stands for Pin Grid Array, not A, C, or D. A is incorrect because it combines two technical terms and does not accurately represent the acronym PGA. C and D are also incorrect because they use different words than "Pin" and do not accurately represent the acronym. The correct answer B accurately represents the acronym and is a commonly used technology term.
