All language subtitles for 6_Mobile Devices

Hi there, it's me again.

You might remember me
from the previous module,

and no worries if not,

what's important is
that I'm here now.

We've made some updates to

this program to make sure you've

got the latest info
on mobile devices.

You'll see me again throughout
the rest of this program.

So keep your eyes peeled for me.

Let's talk about mobile devices.

Mobile devices are computers
too, they have CPUs,

RAM, storage, power
systems and peripherals.

How are they different
from a server,

a desktop computer or a laptop?

There are special
because they're mobile.

They're portable and usually
powered by batteries.

Some mobile devices are

general purpose
computing devices,

like tablets or smartphones.

Other mobile devices
are optimized to

perform a specific set of tasks,

like fitness monitors,
e-readers, and smartwatches.

Mobile devices are
usually very integrated.

Remember the systems that
we showed you earlier,

the components can be taken
out and held in your hand.

Mobile devices build
some or all of

these components together in

a way that you can't take apart.

The smaller device, the more

integrated the
components usually are.

The CPU, RAM, and storage might

be soldered directly to
the devices motherboard.

Very small mobile devices use
a system on a chip or SOC.

A system on a chip
packs the CPU,

RAM and sometimes even the
storage onto a single chip.

Not only our SOC is small,

they use less battery power than

if those components
were separated.

Even though they're small

some mobile devices
use peripherals.

Smartphones connect to Bluetooth
headphones, for example.

Mobile devices can
also be a peripheral.

A fitness tracker is
a standalone device,

but it can also be a
peripheral to your smartphone.

That same fitness tracker might

use a heart rate monitor
as a peripheral.

It's peripherals
all the way down.

Mobile devices may use

standard or proprietary
ports and connectors.

You might need to
have a specific

adapter or connector for

charging a device or

connecting your mobile
device to a computer.

Sometimes the physical shape
or the intended use of

the mobile device makes

a standard connection
like USB, a bad choice.

For example, say you have a
waterproof fitness tracker.

If it had a micro-USB for,

that port will be damaged
if exposed to water.

So instead, it's
designed with a custom

charging interface that can
be submerged underwater.

Here are some of the
standard power data and

display connector types you'll

find used in mobile devices.

This is a USB-C,

next we have a
lightening adapter,

then a mini USB,

and a micro-USB, a micro HDMI,

and the mini HDMI,

and this is a mini display port.

Because of mobile
devices are generally

small and have limited
access to power,

they run operating systems
and application software

that specifically designed to
maximize their performance.

Will dive into mobile
operating systems

and applications
in future videos.

As an IT support specialist,

you might be
responsible for helping

end-users with their
mobile devices.

This might include setup,

troubleshooting, repairing,
and replacing mobile devices.

Don't worry, we're going to
break all this down for you.

One super important thing,

mobile devices can contain
a lot of personal data.

Some organizations
allow people to use

their own personal
devices for work.

We call this bring your
own device or BYOD.

You should be careful to respect

people's privacy when they bring

their own devices
to you for help.

To know how to handle
these devices is

always best to refer to
your organization's policy.
