Final answer:
An intra sector system is a system with multiple components from the same sector. It's analyzed in the context of comparative international systems, looking at the relationships between states within a global system.
Step-by-step explanation:
An intra sector system is a system composed of multiple components within the same sector. It emphasizes the interrelationships and interactions among different elements that function within the same domain or industry. This concept contrasts with intersectoral systems, which involve components from various economic, social, or political sectors.
The term is relevant to the study of comparative international systems, which focus on understanding how different political entities, commonly referred to as states, interact within the broader context of global political and economic systems. Such systems are characterized by independent actions of the units, yet their behaviors are interdependent based on the interactions and systemic effects shaped by the environment they share.
In the context of the mentioned textbook discussing world history, the comparative study of international systems would analyze the systemic relationships between these states and their collective impact on global dynamics, rather than focusing on individual historical events.
