Linux is a multi-user, multitasking operating system with a UNIX-compatible kernel. It provides a platform for running applications with a wide range of functionality. The kernel manages the resources of the system and provides a variety of services to application programs. User programs request services from the kernel through system calls. The kernel schedules the execution of processes and allocates system resources to them. It also handles interrupts from hardware devices.<\/p>\n

The Linux architecture is a family of computer architectures based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds.<\/p>\n

What are the different architectures in Linux? <\/h2>\n

There are a variety of CPU architectures that are used in different computing devices. Each architecture has its own specific features and benefits. Here is a brief overview of some of the most common CPU architectures:<\/p>\n

ARC Architecture: The ARC architecture is used in Linux kernel for ARC processors. This architecture is designed for efficient processing and supports a wide range of instruction sets.<\/p>\n

ARM Architecture: The ARM architecture is used in ARM Linux 26 and upper. This architecture is designed for low power consumption and is widely used in mobile devices.<\/p>\n

ARM64 Architecture: The ARM64 architecture is used in ACPI tables. This architecture is designed for high performance and supports a large number of instructions sets.<\/p>\n

IA-64 Architecture: The IA-64 architecture is used in Linux kernel release for the IA-64 Platform. This architecture is designed for high performance and supports a large number of instructions sets.<\/p>\n

LoongArch Architecture: The LoongArch architecture is used in m68k architecture. This architecture is designed for efficient processing and supports a wide range of instruction sets.<\/p>\n

MIPS-specific Documentation: The MIPS-specific documentation is used in Nios II Specific Documentation. This architecture is designed for low power consumption and is widely used in mobile devices.<\/p>\n

The Linux operating system’s architecture mainly contains some of the components: the Kernel, System Library, Hardware layer, System, and Shell utility. The Kernel is the heart of the operating system and it manages all the resources. The System Library provides a set of common functions and it is used by the Kernel and the applications. The Hardware layer provides the interface between the Kernel and the hardware. The System provides the user interface and it is responsible for the user interaction. The Shell utility provides a command line interface for the user.<\/p>\n

How do I know my Linux architecture <\/h3>\n

The getconf command can be used to check if the kernel is 32-bit or 64-bit.<\/p>\n

The uname command can be used to check the system information, including the kernel version and whether the kernel is 32-bit or 64-bit.<\/p>\n

The \/proc\/cpuinfo file can be used to determine if the CPU is 64-bit or 32-bit.<\/p>\n

Linux utilizes the monolithic kernel, which means that all of the operating system’s core functions are contained within a single large program. Windows uses the micro-kernel, which means that the operating system’s core functions are divided into a number of small programs. The path separator that Linux uses is Slash, while the path separator that Windows uses is backward slash.<\/p>\n

What are the three types of Linux? <\/h2>\n

There are many popular Linux distributions available, each with its own unique features and benefits. Debian, Fedora Linux, and Ubuntu are some of the most popular options, each offering a different take on the Linux experience. Lubuntu and Xubuntu are two of the most popular modifications of Ubuntu, each providing a unique set of features and benefits. Ultimately, the best Linux distribution for you will depend on your specific needs and preferences.<\/p>\n

A user account is a record of all the information and settings associated with a particular user on a computer or other system. There are three types of user accounts: super user, normal user, and system user.<\/p>\n

A super user is an administrator with full privileges to access and modify all files and settings on a system. A normal user has limited privileges and can only access and modify certain files and settings. A system user is an account that is created only for a specific purpose or software.<\/p>\n

What are the two types of Linux? <\/h2>\n

An enterprise distro is a commercial Linux distro that’s supported and maintained by a company. These companies typically offer support contracts for their enterprise distros.<\/p>\n

The two most popular community Linux distros are Ubuntu and Fedora. The two most popular enterprise Linux distros are Red Hat Enterprise Linux and SUSE Linux Enterprise Server.<\/p>\n

The five Linux process states are: running & runnable, interruptable_sleep, uninterruptable_sleep, stopped, and zombie. Each state has its own purpose and is used for different purposes.<\/p>\n

Running & runnable: This state is used when a process is actively running or able to run.<\/p>\n

Interruptable_sleep: This state is used when a process is sleeping and can be interrupted.<\/p>\n

Uninterruptable_sleep: This state is used when a process is sleeping and cannot be interrupted.<\/p>\n

Stopped: This state is used when a process has been stopped and is not able to run.<\/p>\n

Zombie: This state is used when a process has been killed and is no longer running, but its resources are still being used.<\/p>\n

What are the types of Linux OS <\/h3>\n

Linux is a great example of an open source operating system. The source code for Linux is available for anyone to view and use. That means that anyone can view the code, make changes to it, and redistribute it. While the vast majority of users will never need to do this, it’s a great example of how open source can work.<\/p>\n

ARM processors are becoming more popular due to the massive popularity of smartphones. Microsoft has even issued a lighter version of Windows 10 that runs on ARM processors. ARM has also integrated with Linux for the Raspberry Pi OS, although capabilities are limited.
