real-time programming languagesstandardsThe paper gives an overview over an operating system which provides for a flexible interface to support a wide spectrum of real-time language facilities. Due to its modular structure it can be tailored to the requirements of the language. In many cases this...

A 32-bit operating system can only use up to 4GB of RAM, while a 64-bit operating system can theoretically use up to 16 exabytes of RAM (although practical limits are much lower). Additionally, 64-bit systems can execute larger chunks of data at once, which can lead to faster performanc...
As mentioned earlier, although computer families such as the IBM PC-compatible and Macintosh can be distinguished on the basis of CPU type, it is primarily their choice of operating system which gives them their particular identity. Although other operating systems are available for IBM PC-compatibl...
