Now, let's talk about mobile operating systems.
So far, we've talked about
two broad categories of mobile devices.
Some mobile devices are
general-purpose computing devices
like tablets or smartphones.
Other mobile devices like fitness monitors, e-readers,
and smartwatches are designed
to do a smaller set of tasks.
General-purpose mobile devices generally use
a mobile operating system that's
derived from other operating systems.
For example, Android is derived from Linux
and iOS shares a lot of core components with Mac OS.
So how are mobile operating systems
different from the OS's that they're based on?
Mobile devices run on batteries that have to be
recharged or replaced on a regular basis.
You want the device to last as long
as possible between charges.
So mobile operating systems are
optimized to use as little power as possible,
for example, by removing
OS features and applications
that the mobile device doesn't need.
We also use motion, touch,
and voice to interact with mobile devices in
very different ways from desktop or server computers.
This requires adding device drivers
and support to the mobile operating system.
More specialized mobile devices
like fitness trackers, e-readers,
and GPS devices often used custom
OS's that are optimized
for what the device is designed to do.
These devices are even more slimmed down to run
on very minimal hardware with very minimal battery power.
They might also be built using specialized chips and
peripherals which more general
purpose operating systems don't know how to run.
We've linked to some examples of
these specialized mobile operating systems
in the supplemental reading.
There's a bunch more to learn about working with
mobile operating systems and
we'll dive into that in another course.
