Arch Linux ARM
Arch Linux ARM is a port of Arch Linux for ARM processors. Its design philosophy is "simplicity and full control to the end user," and like its parent operating system Arch Linux, aims to be very Unix-like. History and development Arch Linux ARM is based on Arch Linux, which is a minimalist Linux distribution first released on March 11, 2002. The idea of making a single, official port of Arch Linux for devices with ARM processors was born from members of the Arch Linux PlugApps and ArchMobile development teams, notably Mike Staszel, who went on to found the Arch Linux ARM project. Kevin Mihelich is currently Arch Linux ARM's primary developer. Arch Linux ARM is community-developed, with software development and user support provided fully by volunteer effort and donations. Also, unlike other community-supported operating systems such as Ubuntu, Arch Linux ARM has a relatively small user base, making user participation in development especially important.

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

ARMv8
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses cores that implement these ISAs. Due to their low costs, low power consumption, and low heat generation, ARM processors are useful for light, portable, battery-powered devices, including smartphones, laptops, and tablet computers, as well as embedded systems. However, ARM processors are also used for desktops and servers, including Fugaku, the world's fastest supercomputer from 2020 to 2022. With over 230 billion ARM chips produced, , ARM is the most widely used family of instruction set architectures. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samsung Chromebook 2
Samsung Group (; stylised as SΛMSUNG) is a South Korean multinational manufacturing conglomerate headquartered in the Samsung Town office complex in Seoul.

Odroid
The ODROID is a series of single-board computers and tablet computers created by Hardkernel Co., Ltd., located in South Korea. Even though the name ''ODROID'' is a portmanteau of ''open'' + ''Android'', the hardware is not actually open-source hardware, open source because some parts of the design are retained by the company. Many ODROID systems are capable of running not only Android, but also regular Linux distributions. Hardware Several models of ODROID's have been released by Hardkernel. The first generation was released in 2009, followed by higher specification models. C models feature an Amlogic system on a chip (SoC), while XU models feature a Samsung Exynos SoC. Both include an ARM architecture, ARM central processing unit (CPU) and an on chip graphics processing unit (GPU). CPU architectures include ARMv7-A and ARMv8-A, on board memory range from 1 GB RAM to 4 GiB RAM. Secure Digital SD cards are used to store the operating system and program memory in eithe ...
