The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The question asks us to identify the correct statements regarding the core concepts, characteristics, and examples of an Operating System (OS).
Step 2: Detailed Explanation:
Let us evaluate each of the given statements:
• Statement A: An operating system is system software that acts as an intermediary or interface between a user and the computer hardware. Thus, this statement is correct.
• Statement B: By providing an abstract, user-friendly interface (either Graphical User Interface - GUI or Command Line Interface - CLI) and hiding complex hardware processes, the operating system makes a computer system much easier to use. Thus, this statement is correct.
• Statement C: One of the primary jobs of an operating system is resource management, which includes managing memory, processors (CPU), devices (I/O), and files. Therefore, stating that it does not manage resources is incorrect.
• Statement D: Computer software is broadly divided into System Software and Application Software. An operating system is system software, not application software. Therefore, this statement is incorrect.
• Statement E: Linux, MS DOS, Microsoft Windows, and Solaris are indeed classic, well-known operating systems. Thus, this statement is correct.
Step 3: Final Answer:
Based on our analysis, only statements A, B, and E are true. This corresponds to option (B).
