JX is a microkernel operating system with both the kernel and applications implemented using the Java programming language. == Overview == JX is implemented as an extended Java Virtual Machine (the ''JX Core''), adding support to the Java system for necessary features such as protection domains and hardware access, along with a number of components written in Java that provide kernel facilities to applications running on the computer. Because Java is a type-safe language, JX is able to provide isolation between running applications without needing to use hardware memory protection. This technique, known as language-based protection means that system calls and inter-process communication in JX does not cause an address space switch, an operation which is slow on most computers. JX runs on standard PCs, with support for a limited range of common hardware elements. It is open source software, developed by the University of Erlangen.〔(【引用サイトリンク】url=http://www4.informatik.uni-erlangen.de/Projects/JX/index.html )〕 The primary benefits of JX include: * a small trusted computing base (TCB) results in a high security system * lack of address space switching enables high performance compared to most microkernel systems 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「JX (operating system)」の詳細全文を読む スポンサード リンク
