A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.
An operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs.
Palm OS is a discontinued mobile operating system initially developed by Palm, Inc., for personal digital assistants (PDAs) in 1996. Palm OS was designed for ease of use with a touchscreen-based graphical user interface. It was provided with a suite of basic applications for personal information management. Later versions of the OS were extended to support smartphones. The software appeared on the company's line of Palm devices while several other licensees have manufactured devices powered by Palm OS.
In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction services to higher-level software such as an operating system.
Psion PLC was a designer and manufacturer of mobile handheld computers for commercial and industrial uses. The company was headquartered in London, England, with major operations in Mississauga, Ontario, Canada, and other company offices in Europe, the United States, Asia, Latin America, and the Middle East. It was a public company listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index.
An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use. In 2009, it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems.
Palm is a now discontinued line of personal digital assistants (PDAs) and mobile phones developed by California-based Palm, Inc., originally called Palm Computing, Inc. Palm devices are often remembered as "the first wildly popular handheld computers," responsible for ushering in the smartphone era.
Computer operating systems based on the Linux kernel are used in embedded systems such as consumer electronics, in-vehicle infotainment (IVI), networking equipment, machine control, industrial automation, navigation equipment, spacecraft flight software, and medical instruments in general.
In computer science, hierarchical protection domains, often called protection rings, are mechanisms to protect data and functionality from faults and malicious behavior.
Linux is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project.
HAL is a software subsystem for UNIX-like operating systems providing hardware abstraction.
Swami Manohar, otherwise known as Manohar Swaminathan, is a co-founder and the CEO of PicoPeta Simputers Pvt. Ltd. He completed his undergraduate program in Electronics and Communication Engineering in Government College of Technology, Coimbatore during which he was a part of a campus team that designed an Electronic Voting machine in the year 1981, which was actually the first designed in India. After obtaining his PhD in Computer Science from Brown University he was a faculty at the University of North Carolina for two years and then was at the Indian Institute of Science (IISc), Bangalore, between 1990 and 2005. He was on the faculty of the department of Computer Science and Automation (CSA) and the Supercomputer Education and Research Center (SERC) at the Institute. He has been a visiting faculty at Columbia University, University of Missouri and the University of Texas. While at IISc, he co-invented the Simputer, was awarded the Dewang Mehta Award for Innovation in IT, and pioneered the faculty entrepreneurship activity at IISc, which has since catalyzed similar activity in IITs and other educational institutes in India. He co-founded Strand Life Sciences, and String Labs, the first academic incubating company in India.
The Sinomanic Tianhua GX-1C is a specially tailored subnotebook for primary and secondary school students in the People's Republic of China. It uses the Loongson I (Longxin) CPU. The device is designed for use as an educational aid and to introduce young students to computers.
Linpus Linux is a Fedora Linux-based operating system created by the Taiwanese firm Linpus Technologies Inc. Linpus was designed specifically to fully support the Asian market, with full Unicode support for the Chinese and Japanese languages. A special version, Linpus Lite, was written to run on devices with lower-cost hardware such as netbooks. It has both an icon and tab-based "Simple mode", designed for new users; and, a conventional style "PC mode" for those wanting a more Microsoft Windows–like interface. It is targeted at handheld devices with smaller screens, and supports resolutions as low as VGA.
Bharat Operating System Solutions is an Indian Linux distribution based on Debian. Its latest stable version is 10.0 (Pragya), which was released in March 2024.
The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the utilization of common resources e.g. CPU & cache usage, file systems, and network sockets. On most systems, the kernel is one of the first programs loaded on startup. It handles the rest of the startup as well as memory, peripherals, and input/output (I/O) requests from software, translating them into data-processing instructions for the central processing unit.
The Dingoo is a handheld gaming console that supports music and video playback and open game development. The system features an on-board radio and recording program. It was sold to consumers in three colors: white, black, and pink. It was released in February 2009 and had sold over 1 million units.
zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk. The two most common uses for zram are for the storage of temporary files and as a swap device. Initially, zram had only the latter function, hence the original name "compcache". Unlike swap, zram only uses 0.1% of the maximum size of the disk when not in use.
A supercomputer operating system is an operating system intended for supercomputers. Since the end of the 20th century, supercomputer operating systems have undergone major transformations, as fundamental changes have occurred in supercomputer architecture. While early operating systems were custom tailored to each supercomputer to gain speed, the trend has been moving away from in-house operating systems and toward some form of Linux, with it running all the supercomputers on the TOP500 list in November 2017. In 2021, top 10 computers run for instance Red Hat Enterprise Linux (RHEL), or some variant of it or other Linux distribution e.g. Ubuntu.
PICO-8 is a virtual machine and game engine created by Lexaloffle Games. It is a fantasy video game console that mimics the limited graphical and sound capabilities of the old 8-bit systems of the 1980s to encourage creativity and ingenuity in producing games without being overwhelmed with the many possibilities of modern tools and machines. Such limitations also give PICO-8 games a particular look and feel.
