Which part of the operating system permits an operator to get information?

• A. Kernel
• B. User Interface
• C. File System
• D. Scheduler

Answer: (B)

The part that lets an operator obtain information from the system is the user interface. This layer presents status, messages, and controls in a human-friendly form, whether through a command-line shell or a graphical dashboard. It’s the gateway you use to see what’s running, how resources are being used, logs, errors, and other vital details about the system. The kernel, while essential, operates behind the scenes to manage hardware and core services and isn’t designed to present information to a user in a friendly way. The file system stores data and metadata about files, not system status. The scheduler decides which processes run on the CPU, focusing on execution order rather than delivering information to the operator.
