When you enter a command it invokes a program. While this program is running it is called a process . It is important to grasp that although there is only one copy of a program held in the file system , any number of processes can be invoked which run this program. When the operating system is started after a boot , a single process is started. ... Any processes that are started from within your shell - such as entering a command - are the children of this process. ...

The information path to prepare, perform and reduce a radioastronomical observation, using the Arcos correlator , is schematized in the figure: . The programs reside part on the computer network of the Arcetri Observatory, and part at the Medicina Radio Telescope . All programs running at Arcetri are written for a Sun workstation, and are public domain software, available upon request. Programs running at the telescope are written for a PC with DOS/Windows (or Linux).
