Unix was designed to be a time-sharing system, and as such has been multiuser since its inception. Users are identified in Unix by their usernames, but internally each is represented as a unique identifying integer called a user ID, or UID. Each user can also belong to one or more group...

BSD is a carefully engineered, mature operating system with many capabilities. In fact, most of today’s commercial UNIX and UNIX-like operating systems contain a great deal of BSD code. BSD also provides a set of industry-standard APIs. New technologies, such as the I/O Kit and Network ...
Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. It has all the features you would expect in a modern fully-fledged Unix, ...
ld是linker的缩写，gcc 是gnu complier collection,而gnu是取意gnu is not unix,这些需要自学。
A kernel is often contrasted with ashell, which is the outermost part of an OS that interacts with user commands. Kernel and shell are terms used more frequently inUnixOSes than in IBM mainframe and Microsoft Windows systems. A kernel isn't to be confused with a BIOS, which is an indepen...
NXOS是Next XBook Operating System的意思,是一个跨平台的简洁、高性能、高稳定性的支持多核的操作系统内核,它将应用于桌面操作系统领域,服务器操作系统领域以及移动终端操作系统领域。 我们以简洁、高效、稳定为核心,用比较简洁且高效的方式去实现一些功能,去掉一些复杂,冗杂的功能,化繁为简。 我们的目标是针对不同...
The BSD operating system, often referred to simply as "BSD," stands for Berkeley Software Distribution. It is a family of Unix-like operating systems that originated from the University of California, Berkeley in the late 1970s and early 1980s. The BSD operating systems are known for their ...
The kernel of an operating system is its core — it’s the building block upon which the rest of the OS is built. In macOS’ case, the kernel is based on Unix. That’s why, for example, we use UNIX commands in Terminal, Mac’s command-line interface. The process called kernel_task...
