Knowing the terminology of the components of a computer system is a critical skill technical support engineers need to have. This question is interesting because it refers to a technology developed roughly 40 years ago and is no longer used. However, a few of these systems may still be in use at Palo Alto Networks, so you need to be familiar with the terminology in what it represents. Additionally, having a historical perspective on the IT industry enhances your skills and makes you more valuable as a technical support engineer.
