That's not a very fair question for an intro level class.
The really short answer is "Many millions of lines of code".
The not so short answer would be that Unix is an OS, copyright owned by Bell Labs while Linux is a kernel, and depends on a crapload of utilities from the GNU project to put the whole OS together. Linux tries to be POSIX compliant, I'm not sure Unix is entirely POSIX compliant either.
The longer answers would explain the differences in the kernel architectures, schedulers, process tables, device handling, etc. Feelings about how those would work in the "perfect system" are the types of feelings that start flamewars.
Good luck with your class!
LOL! I'm not finding alot of the questions fair for an intro class, espicially when they are not covered in the course material, worst off, this is a week 1 lab question. I'm still stuck on wk 1 lab and I'm already in wk 3
Thanks for the reply

ISWPRINT(3) Linux Programmer's Manual ISWPRINT(3)
NAME
iswprint - test for printing wide character
SYNOPSIS
#include <wctype.h>
int iswprint(wint_t wc);
DESCRIPTION
The iswprint() function is the wide-character equivalent of the isprint(3) function. It tests whether wc is a wide character belonging to
the wide-character class "print".
The wide-character class "print" is disjoint from the wide-character class "cntrl".
The wide-character class "print" contains the wide-character class "graph".
RETURN VALUE
The iswprint() function returns nonzero if wc is a wide character belonging to the wide-character class "print". Otherwise, it returns
zero.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).
