In Class 9 Artificial Intelligence, this topic from ICT (Information & Communication Technology) Skills-I introduces students to the role of an operating system in managing computer hardware, software, files, and user interaction. Students learn how to navigate the desktop, open and close applications, create and organize folders, and manage files through actions such as naming, saving, copying, moving, renaming, and deleting. The topic also develops orderly digital work habits and responsible handling of stored information.
TOPIC PRACTICE
Up to 10 questions from this page. Select your focus, then start.
Permission inheritance is an access-control concept in which permissions assigned to a parent folder can flow down to its child subfolders and files. Therefore, option C is correct. It does not determine a file’s name or size, and it does not delete files. Administrators should review inherited permissions carefully because a broad parent permission may unintentionally grant access to sensitive items.
File ownership identifies the account or user responsible for a file and may give that owner special authority to manage its permissions, depending on the operating system. Option D is correct. Ownership does not compress a file, change its format, or hide it automatically. Ownership and permissions are related but different: permissions define allowed actions, while ownership identifies who can administer or alter access settings.
Mounting is the operating-system operation that makes a storage device or file system available at a chosen location in the directory tree, called a mount point. Option A is correct because users can access the stored files through that location after mounting. Mounting is not deletion, a physical monitor action, or printer maintenance; those distractors describe unrelated operations.
Unmounting tells the operating system to stop using the mounted file system and to complete or flush pending write operations. This reduces the chance that directory information or file contents remain only partly updated. Therefore, option B is correct. Unmounting does not increase capacity, rename files, or shut down the CPU. Removing storage without unmounting can cause data loss or file-system corruption.
A disk quota sets a maximum amount of storage that a particular user or group may consume on a system. Option C is correct because quotas help prevent one account from filling a shared disk and leaving no space for others. A quota does not grant administrator rights, move every file into one folder, or hide file extensions. It is a resource-management control, not a file-format feature.
A file-system checking tool examines the logical structure of a storage system, including directories, file records, and allocation information. It can report or repair inconsistencies caused by errors, improper shutdowns, or damaged metadata. Therefore, option D is correct. It does not change monitor resolution, translate language, or create printer drivers. Important data should be backed up before repairs are attempted.
An off-site backup protects data from incidents that affect the main location, such as fire, theft, flooding, or another local disaster. If every copy is stored in the same place, one event can destroy them all. Therefore, option A is correct. Changing extensions, speeding up the operating system, and increasing monitor brightness are unrelated to backup resilience. Backups should also be tested by restoring sample data.
In the ready state, a process has all resources needed to run except immediate access to the processor. It is placed in the ready queue and waits for the scheduler to allocate processor time. Therefore, option A is correct. A terminated process is no longer running, while waiting or blocked describes a process waiting for an input or event rather than merely waiting for the processor.
A process enters the waiting, or blocked, state when it cannot continue until an external condition is satisfied, such as input arriving, a disk operation completing, or a required event occurring. Option B is correct. Renaming a process, switching off a monitor, or compressing a file does not by itself define this state. After the event occurs, the process usually returns to the ready state.
During a context switch, the operating system saves the current process’s execution context, such as processor registers, the program counter, and relevant scheduling information. It then loads the saved context of another process so multitasking can continue. Therefore, option C is correct. A file name, monitor brightness, or printer ink level is not the process context required to resume execution accurately.
