In which operating system jobs are executed in groups?a) Batch Processing b) Time Sharingc) Single User d) Real Time

Break Down the Problem

1. Identify the characteristics of each operating system type listed in the options.
2. Determine which type of operating system executes jobs in groups.

Relevant Concepts

1. Batch Processing: Jobs are collected and processed in batches without user interaction during execution.
2. Time Sharing: Multiple users share system resources simultaneously, allowing for interactive job execution.
3. Single User: The system is dedicated to one user at a time, often at interactive levels.
4. Real Time: Jobs are processed with strict timing constraints, often needed for critical systems.

Analysis and Detail

1. In Batch Processing systems, jobs are queued and executed in groups without user interaction, which allows for efficient resource utilization.
2. Time Sharing systems focus on quick response times and interactivity, where jobs do not necessarily run in groups.
3. In Single User systems, only one user can execute jobs at a time, which is not conducive to grouped job execution.
4. Real Time systems prioritize immediate processing based on time constraints, typically focusing on individual job execution rather than groups.

Verify and Summarize

From the analysis, Batch Processing is the only operating system type that executes jobs in groups, as it processes multiple jobs together, optimizing resource use.

Final Answer

The correct option is a) Batch Processing.
