Hercules is a computer emulator allowing software written for IBM mainframe computers and for plug compatible mainframes to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems programmer.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
A computing platform, digital platform, or software platform is an environment in which software is executed. It may be the hardware or the operating system (OS), a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.
WPS Office is an office suite for Microsoft Windows, macOS, Linux, iOS, Android, and HarmonyOS developed by Zhuhai-based Chinese software developer Kingsoft. It also comes pre-installed on Fire tablets. WPS Office is made up of three primary components: WPS Writer, WPS Presentation, and WPS Spreadsheet. By 2022, WPS Office reached a number of more than 494 million monthly active users and over 1.2 billion installations.
A netbook is a small and inexpensive laptop designed primarily as a means of accessing the Internet. Netbooks were sold from 2007 until around 2013, when the widespread advent of smartphones and tablets eclipsed their popularity. Netbooks generally had lower-end hardware specifications than consumer laptops of the time, being primarily intended as clients for Internet services. While netbook has fallen out of use, these machines evolved into other products including Google's Chromebook, and mobile devices, particularly tablet computers, often running mobile operating systems such as iOS or Android.
These tables provide a comparison of operating systems, of computer devices, as listing general and technical information for a number of widely used and currently available PC or handheld operating systems. The article "Usage share of operating systems" provides a broader, and more general, comparison of operating systems that includes servers, mainframes and supercomputers.
The following tables compare general and technical information for a number of office suites:
This is a comparison of word processing software.
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules.
ptrace is a system call found in Unix and several Unix-like operating systems. By using ptrace one process can control another, enabling the controller to inspect and manipulate the internal state of its target. ptrace is used by debuggers and other code-analysis tools, mostly as aids to software development.
Comparison of user features of operating systems refers to a comparison of the general user features of major operating systems in a narrative format. It does not encompass a full exhaustive comparison or description of all technical details of all operating systems. It is a comparison of basic roles and the most prominent features. It also includes the most important features of the operating system's origins, historical development, and role.
