- Let's talk about tablets.
This is a tablet computer.
It's a thin mobile device.
We operate it by tapping on the touchscreen
to do what we need here.
I think everyone who's watching this video is
pretty familiar with how to operate one of these.
So, let's get into the details of these.
Now these generally measure between six and 10 or 11 inches
and that's measured diagonally by the screen size
by the display size.
You can use these for simple tasks
such as reading books or browsing the internet
but you can use them for more complex tasks as well.
If you have a more powerful tablet
you could do more than that.
You can go and do recording, editing,
photo editing, even programming
but you have to make sure you match
the tablet with what you need, the specs of the tablet
with what you need for your applications.
And the main reason that I have this, this is an Apple iPad.
The main reason I have this
is so I can use it as a control surface
for my wireless recording for video.
All my cameras are hooked up to a hub that's over here
and it's a wireless hub
and this program actually controls that
it's all done wirelessly.
And so, that's the main purpose for this.
So, need a good amount of power on the tablet
in order to run this program and control that wireless hub.
So you gotta use the right tool for what you need.
Okay, so I mentioned these screens
they're usually six to say, 11 inches diagonal.
And this particular one is a 9.7 inch display.
This is an Apple iPad 2017 model
it's LED backlit so, it's using diodes
and it's a multi-touch display.
So, that means that we can tap with one finger
and we can use multiple fingers to swipe
and to move to other apps,
to close apps with the five fingers swipe and so on.
And these are capacitive touchscreens.
Again, they can respond to one or more fingers
but also they can respond to specialized stylus devices.
Now these are usually proprietary.
So, if you're using an iPad, you'd need an Apple pencil
special stylus that you can use.
This one is a Samsung stylus, so this one's not gonna work
but it will work on Samsung devices.
So, you could use specific stylus or styli
for these multi-touch screens as well.
And this particular one uses IPS, in-plane switching.
So we can have a wider viewing angle.
And in fact, you can see here we can go pretty wide
and you can still see everything on the screen very well
so that's IPS.
And this one is a Quad Extended Graphics Array, QXGA.
And it has a resolution of 2048 across by 1536 up and down.
And that's a four to three aspect ratio.
And you may say, well four to three aspect ratio
that sounds kind of old school like CRT monitors
but that's what iPads and a lot of tablets use.
And you would say well,
most laptops that I see are 16 by nine
and PCs are 16 by nine or 16 by 10.
And why is that?
Well with the four by three aspect ratio
you get a little bit more space, a little bit more height.
So if you have an on-screen keyboard that pops up
you'll only lose about this much up to here
and you'll still be able to see up up here.
And that works a little bit better
than having a wider screen, like a 16 by nine.
So, quite often you'll see that
plus it kinda works for handling the device as well.
Now, this one has a 1.85 gigahertz CPU
and there's two main goals for these tablets.
The first, is to be highly portable.
You wanna be able to move it around,
to do what you need to with it,
long battery power, portable, but then also
you wanna have powerful processing capabilities
but it's such a small device.
In order to accomplish this
what we use is a system on a chip or SOC.
What that does is it combines a CPU, RAM, storage, and more
like it's an entire system on a single substrate
essentially a system unto itself.
And the CPU that's used is arm-based A-R-M.
And that's a type of reduced instruction set computing risk.
And the idea is an Arm-based CPU uses less transistors
than a CPU you would find in a PC or a laptop.
And that uses less space, it's lower power consumption
but still you get a lot of processing power.
So, the Arm-based CPU system on a chip is very common
for mobile devices like tablets and smartphones.
Built into that system on a chip, you'll have DDR RAM.
In this case, this one has two gigahertz of LP DDR4 RAM.
Smaller form factor than any other DDR you'll find in a PC
or SO-DIMM that you'll find in a laptop.
Quite often with tablets you'll have
beyond the memory beyond the RAM
which is usually two, gig four gigs, six gig
currently as of the recording of this video,
you'll also have long term storage,
permanent storage between say 32 and 256 gigabytes.
And that's flash memory similar to a USB flash drive.
This one has 128 gigabytes.
These also come with a long life battery
and all these devices today use
lithium ion polymer batteries,
Li-ion polymer batteries.
And so it's similar to the lithium ion batteries and laptops
but these could be made into any shape
so, you can shape it to what you need for this device.
This particular one is 8,827 milliamp-hours
otherwise known as 32.4 watt-hours.
And what that effectively means is
you can work on it typically for about 10 hours
on a full charge.
And then you have cameras.
You have some built in cameras here.
And here we have one on the back.
That's the more powerful camera.
This is an eight megapixel camera.
So, you can take very large pictures
and you can record at 1080P,
that's 1920 by 1080 resolution video recording.
And then these usually have a second camera
on the front here.
And that's used for doing things like FaceTime or Skype
or what have you communicating with people.
And so, that camera is a 1.2 megapixel camera.
So much smaller pictures, and it does 720p video.
That's 1080 by 720 resolution, still high def
but the lowest version of high def that's available to you.
So, there's some of the details of this device.
And again, there are different types of tablets.
Okay, here we have an Amazon Fire and this is a Kid's Fire.
And it's a pretty nice device.
It's really good for reading books or for doing basic apps
and things like that
but this would never be able to handle
the video recording that I need to do.
It doesn't have a powerful enough processor.
It's not meant to do that type of stuff.
It's a much more inexpensive device.
And so this is good for kids,
it's good for adults who just wanna read or browse the web.
But if you want to get into something
where you've got real power,
you're gonna need something more powerful, right?
And like I was saying, I'm using this wireless hub
to record what we have here, record my various video devices
and switch between different screens.
And so you need something like an iPad.
In fact, it's proprietary for this program gotta use an iPad
but you might wanna work with something else as well.
For example, if you need something powerful
that's Android based, you might go at something by Samsung.
And kind of bridging the gap between laptops and tablets.
You have the surface, the Microsoft Surface
which of course will run Windows,
but those are touch screens they come with a keyboard.
So, it's a laptop it's a tablet
who knows you can call it whatever you want really.
And sometimes they'll even call it both.
They'll call it a surface, they'll call it the laptop
sometimes they'll it a tablet
'cause it all depends on how you're using it.
Are you using that keyboard
or you just have it flat in tablet mode?
So, the whole idea here again is
that you wanna use the right device
and depending on what type of device you use
you're gonna have a different connector for charging
and for synchronization of data.
This one, this iPad uses a lightning connector.
And that's an example of that.
Again for charging, and you could probably hear that
now it's charging and it's also for synchronization of data.
This one uses a USB connection and that is a micro-USB
which will show again and we've shown before
but you might have a device also that uses USB-C.
And so here's a quick view of both of those.
On the right we have the micro-USB
and on the left we have the USB-C.
So you wanna know the differences
between all those micro-USB, USB-C,
and also the lightning connector
that you'll find on iPads and other Apple devices.
So make sure that you understand
the various hardware specifications for a device,
how to read these
and how to understand what it is that they're talking about
and what all these specs mean for these different devices.
And always remember to select the right tool
for the job at hand, for the task at hand.
Whether you're just browsing the web and reading books
or doing some content creation and video editing
and audio editing and things like that.
And keep in mind also, you might have some people
that will refer to a device like this as a tablet
because it's thin and you can read things on it
but really this is just an e-reader.
And what we have here is just black and white.
It's just meant for reading books.
So, it's really not considered a tablet
by technicians and by companies
it's considered an electronic reader or e-reader.
And here we have "The Autobiography of Benjamin Franklin"
if that excites you.
So, different device though
you want to definitely differentiate
between those and tablets.
All right, so a little bit about tablets
and take a look at some of the latest tablets
that are out there today.
Take a look at Apple, Samsung, Microsoft Surface
some of the Kindle devices
look at all the manufacturers out there
and see what they have to offer
and take a look at the specs of those devices
and make sure that you can understand
the different specifications
like the CPU, like the RAM, the flash memory,
the battery, and the display technology,
as well as the cameras.
