questions about Operating System

[RabiDas Sharma]

Hello Everyone
I have got doubt in operating system but couldn't find matching forums so i'm posting my doubt here.
please transfer this question to the concerned forum...

I was going through the memory management done by operating system
but got stuck in paged memory management
My study material says advantage of paged memory management is :There is no external fragmentation here..
But I can't understand how?? please explain... if possible with examples

Also kindly explain segmented memory management....

kindly tell me books that can provide sufficient fundamentals to clear these doubts...

with regard
