Which mobile operating system is based on the Linux kernel?
A iOS
B Android
C BlackBerry
D Windows Mobile
Android is a mobile operating system based on the Linux kernel. It provides an open‐source platform for mobile devices, with a focus on flexibility, customization, and broad device compatibility.
Which of the following is true for iOS compared to Android?
A Open source
B Based on Linux
C Closed source
D Developed by Google
iOS is a closed source mobile operating system developed by Apple. Unlike Android, which is open source, iOS is only available on Apple devices and has a more restricted ecosystem.
What is the primary purpose of the Linux kernel?
A Manage Hardware Resources
B Provide User Interface
C Execute Applications
D Handle Network Traffic
The Linux kernel is responsible for managing hardware resources, such as CPU, memory, and I/O devices. It acts as an intermediary between the hardware and software, enabling the operating system to function effectively.
What is the key feature of the Windows NT architecture?
A Monolithic Kernel
B Task Scheduling
C Microkernel
D Modular Design
Windows NT uses a modular architecture that separates the kernel into components like memory management, I/O subsystem, and file system. This modular approach allows for better performance, maintainability, and scalability.
Which component of a Linux based operating system handles user interactions and system commands?
A Kernel
B User Interface
C Shell
D Device Drivers
The shell is the command line interface (CLI) in Linux. It interprets and executes user commands, allowing users to interact with the system, run programs, and perform administrative tasks.
Which of the following is the primary function of the Windows kernel?
A Manage User Input
B Control Hardware Resources
C Manage User Input
D Provide File Services
The Windows kernel is responsible for managing hardware resources, including memory, CPU, and devices. It ensures that the operating system has the necessary resources to execute processes efficiently and securely.
What is the main advantage of using Shell scripting in an operating system?
A Automation of Tasks
B Faster Execution
C Security Enhancements
D Resource Management
Shell scripting allows users to automate repetitive tasks by writing a sequence of commands in a script. This helps improve efficiency, reduce human error, and automate complex system administration tasks.
What does the Linux kernel handle in terms of system security?
A File System Management
B Data Encryption
C Access Control and Permissions
D Process Scheduling
The Linux kernel plays a crucial role in system security by enforcing access control and permissions. It ensures that only authorized users can access or modify files, processes, and system resources.
What is the role of the Windows file system?
A Data Storage and Retrieval
B Memory Management
C Network Management
D Process Scheduling
The Windows file system is responsible for managing how data is stored, accessed, and organized on storage devices. It provides structure for storing files and directories and includes tools for data retrieval and protection.
What is the purpose of a device driver in the Linux operating system?
A Monitor System Performance
B Manage User Accounts
C Provide Network Access
D Control Hardware Devices
A device driver in Linux acts as an intermediary between the operating system and hardware devices. It translates OS commands into device specific instructions, allowing the OS to control hardware like printers, displays, and storage devices.
Which of the following is true for shell scripts in Unix like systems?
A They are compiled
B They allow for task automation
C They are executed directly by the kernel
D They are written in machine code
Shell scripts are written in a scripting language and are used to automate tasks in Unix like systems. These scripts consist of a series of commands executed by the shell, saving time and improving productivity.
What is the primary function of the Windows Task Scheduler?
A Allocate Memory
B Monitor Network Traffic
C Schedule Tasks for Execution
D Manage File Permissions
The Windows Task Scheduler automates the execution of tasks based on user defined triggers or schedules. It can run programs, scripts, or batch files at specific times or in response to system events.
What is the key difference between Android and iOS in terms of app development?
A iOS uses Java
B iOS is open source
C Android is more restrictive
D Android uses Java or Kotlin
Android app development primarily uses Java or Kotlin, while iOS development uses Swift or Objective C. This difference makes Android development more open source, whereas iOS development is more restrictive and exclusive to Apple’s ecosystem.
What is the main function of the X Window System in Linux?
A Provide a Graphical User Interface
B Manage File System
C Handle Memory Allocation
D Manage Network Traffic
The X Window System in Linux provides the foundation for graphical user interfaces. It manages display, input devices, and window management, allowing users to interact with Linux systems using graphical environments.
How does the Linux kernel handle multitasking?
A Non preemptive Scheduling
B Priority Allocation
C Preemptive Scheduling
D Task Synchronization
The Linux kernel uses preemptive multitasking, which means it can interrupt running tasks to allocate CPU time to other processes. This ensures that multiple processes can execute concurrently without interference.
