What is Embedded Linux?

• Embedded Linux is a version of Linux tailored for embedded systems.

• Embedded Linux is a type of mobile application.

• Embedded Linux is a cloud-based software platform.

• Embedded Linux is a desktop operating system.

Name two advantages of using Embedded Linux.

• High power consumption

• Limited hardware compatibility

• Lack of development tools

• 1. Lightweight and customizable; 2. Strong community support and resources.

What is the role of the Linux kernel in an embedded system?

• The Linux kernel does not interact with hardware in embedded systems.

• The Linux kernel manages hardware resources and provides essential services for applications in an embedded system.

• The Linux kernel is responsible for user interface design.

• The Linux kernel is only used for desktop applications.

Explain the difference between user space and kernel space.

• User space has full access to hardware, while kernel space has limited access.

• User space is for user applications with limited access, while kernel space is for the operating system core with full access to hardware.

• Kernel space is where user applications run, and user space is for system processes.

• User space and kernel space are the same, with no differences in access levels.

What is a device driver in the context of Embedded Linux?

• A device driver is a user interface for managing software applications.

• A device driver is a protocol for network communication in Embedded Linux.

• A device driver is a type of hardware component in Embedded Linux.

• A device driver is a software component that enables communication between the operating system and hardware devices in Embedded Linux.

How do you cross-compile an application for an embedded Linux system?

• Use a cross-compilation toolchain to compile the application for the target architecture.

• Run the application in a virtual machine before deployment.

• Use a standard desktop compiler without any modifications.

• Compile the application directly on the embedded device.

What is the purpose of the BusyBox utility in Embedded Linux?

• To manage hardware drivers in Linux.

• To provide a graphical user interface for Linux systems.

• To serve as a web server for embedded devices.

• The purpose of BusyBox in Embedded Linux is to provide a compact set of Unix utilities in a single executable.

Describe the function of the init system in Linux.

• The init system compiles software applications.

• The init system initializes the system, manages processes, and handles services.

• The init system is responsible for user interface design.

• The init system manages network configurations.

What are real-time operating systems and how do they relate to Embedded Linux?

• Real-time operating systems are slower than traditional operating systems.

• Real-time operating systems are designed for time-sensitive applications, while Embedded Linux can be configured for real-time performance.

• Real-time operating systems are only used in desktop applications.

• Embedded Linux cannot be used for real-time tasks.

List two popular distributions of Embedded Linux.

• Ubuntu Server

• Yocto Project, OpenWrt

• Raspberry Pi OS

• Fedora Core
