Which of the following recent trends can be defined as the abstraction of different computing resources like processor, memory, etc., and is the single most effective way to reduce IT expenses?

Correct option is D

Virtualization is the process of abstracting physical computing resources such as processors, memory, and storage into virtual instances. This technology allows multiple virtual machines to run on a single physical machine, optimizing resource utilization and reducing IT infrastructure costs.
Important Key Points:
1. Virtualization enables businesses to efficiently use their hardware by creating virtual environments for multiple applications and operating systems.
2. It reduces IT expenses by minimizing the need for physical servers and storage.
3. It supports scalability, disaster recovery, and easier management of resources.
Knowledge Booster:
· Artificial Intelligence (AI): Focuses on creating intelligent systems but does not abstract computing resources.
· Clustering: Involves combining multiple computers to work as a single system but is not directly related to virtualization.
· Storage Area Network (SAN): Provides high-speed access to storage but does not involve resource abstraction.
· Virtualization is foundational for cloud computing and modern IT infrastructures.
