... The ESO-MIDAS system is built along lines which should allow easy integration of complex analysis algorithms as well as allowing greater flexibility in interactive use and in the creation of user specific procedures from the basic building blocks. The first design proposal for ESO-MIDAS, made late 1980, used some ideas from the UK STARLINK project for the software interface definitions. ... It consists of the following three parts, the monitor, the applications, and the interfaces. ...

... Two computers in the same network are usually linked via a single physical cable. When they communicate over the network, the programs in each computer that take part in the communication are linked via a virtual connection , a sort of imaginary cable. ... When it notices an incoming network login (i.e., it notices that it gets a new virtual connection to some other computer), it starts a new process to handle that single login. ...
