Cloud Computing MCQ Questions & Answers | Computer Science

JEOS is a term used in cloud computing. It's a short form, and understanding what it stands for is key to understanding how cloud resources are managed.

Let's look at the options: Option A, "joint expensive operating system," and Option B, "just expensive operating system," don't make sense in the context of cloud computing. The word "expensive" isn't typically associated with the core concept of JEOS.

Option D, "joined environmental operating system," is also incorrect. It doesn't accurately describe the functionality or purpose.

The correct answer is Option C, "just enough operating system." This means that the operating system provided in a cloud environment only includes the minimum necessary components to run the required applications. It's a lean and efficient approach, reducing resource usage and improving performance. This is a very common practice in cloud environments to optimize costs and improve security.
