[erlang-questions] A visual tour of Erlang

[Torben Hoffmann]

Hi Anoop,

Erlang has its own VM, so all those processes are very lightweight compared to OS processes. 

The basic unit of computation in Erlang is a process with its own memory space and you can only communicate with a process by sending it a message.  

This set-up is necessary if you want to build a fault tolerant system - the last ingredience is the ability to link and monitor processes. Two linked processes will die if either of them dies. A monitor will be notified if the process it monitors die. 

These simple mechanisms is what allows Erlang to work so well. 

Hope this clarifies things a bit for you. 

Cheers,
Torben
