2. Which of the following statements best differentiates cluster computing from grid computing?
(A) Cluster computing involves geographically dispersed computers working together, whereas grid computing involves computers within a single location working as a single system.
(B) Cluster computing uses a centralized management system to manage a group of tightly connected computers, while grid computing uses a decentralized system to manage a network of loosely connected computers.
(C) Cluster computing is used primarily for high-performance computing applications, while grid computing is used only for data storage purposes.
(D) Cluster computing relies on virtual machines to distribute workloads, whereas grid computing relies on physical machines exclusively.
(E) Cluster computing and grid computing both refer to using multiple computers to solve a problem, but only cluster computing requires specialized hardware.
