I have three questions about translators.
The first is what happens when a server executes a translator? That is, is
the translator run as a layer between the kernel and user app (thereby
making system calls to accomplish things like internally opening
files/directoris as well as using the original port for information to and
from the user app and server)? Or is it run as a layer between the server
and kernel (thereby making server-specific function calls to accomplish the
same things mentioned above)?
Secondly, are the servers and translators run as user processes or system
processes? What about the kernel?
Thirdly, why is there a need for translators? They just seem like an extra
layer (or "middle-man") between the user app-kernel-server connection that
would otherwise occur.
Thanks for the help.
God bless
Hiran
