It is amazing to realize how important operating systems are to computers.
So it is that the study of operating systems is of great importance as part of
studying computers. Operating systems support access and innovation;
they allow the complicated inner workings of hardware to be used with
ease. As computers are developing rapidly, so are operating systems.
It is interesting to note that despite the change and evolution which
operating systems undergo, they also remain constant. The underlying
concepts of operating systems change much more slowly than the ways
to adapt those concepts to new computer systems. As an example, the
idea of a file has been implemented on computers for many years and
will continue to be used for many years to come.
This book is written as an introduction to operating systems, with
a focus on mobile phones and, specifically, Symbian OS. There are
many textbooks that describe most aspects of operating systems, but
most bypass mobile phone operating systems. Symbian OS is a unique
and comprehensive mobile phone operating system and any complete
examination of operating systems should include it.
This book is targeted at junior or senior undergraduate students. In
addition to simply presenting and discussing operating system concepts,
this book is accompanied by exercises that can be performed in the
context of laboratory or experimental assignments. These assignments
can be assigned and worked on in the classroom or a student’s own
time. Hands-on experience can be very important in cementing various
concepts.
