some questions

[sindhoor pangal <sindhoor@xxxxxxxxx>]

hi
i need some info urgently. these questions sound may
sound elementary but i cant find 'exact' answers to
them. so i turn to 'the list'!!!

1. what is the difference between the linux system and
linux distribution. a book says the linux system is a
std environment for applications but does not provide
means of managing the full functionality. what does
that mean ?

2. what is posix compliance ?

3.'linux is not public domain software'. what is
public domain ?

thats it for now :)
