									                              Tablet PC Definitions Explained

When it comes to touch screen tablets you're likely amazed at what these devices can do, but when it
comes to explaining how they work and the plethora of new terms and definitions associated with them
you're probably left asking yourself, what does it all mean? Well fear not because here at EduLabs
Global we aim to educate and entertain while keeping you in the loop regarding what makes tablets
tick! How do we do it? Well that's one of life's mysteries we can't explain, on the other hand, what we
can explain are the following tablet computer definitions.

Before we get started, please let us just say this. Over the past few decades computers have evolved
and come a very long way. How the pattern tends to go is the more that computers evolve the quicker
they evolve and that of course includes tablet PCs. This is good in many ways but keeping up with so
many rapid changes occurring with technology can sometimes be overwhelming. This is why we like to
keep things fun, simple, informative and bring things back to basics. What good is knowledge if you can't
share it with others, especially younger generations who will shape the future?

On that note, let's go for a swim and dive into the large pool of tablet PC definitions. After all, that's
likely what you're here for in the first place! So, as we like to say at EduLabs Global school of the future is
now in session!

What Does IMEI Mean?
IMEI is an acronym for International Mobile Equipment Identity. It is a unique number assigned to each
individual tablet or mobile phone device. It's typically used for validation purposes in case your tablet PC
gets lost or stolen for whatever reason. IMEI enables your tablet PC to be tracked, even if the device is
turned off, and helps prevent unlawful usage and theft of your device.

What Does IMSI Mean?
Like peanut butter and jelly, IMSI works hand in hand with IMEI. It's an acronym for International Mobile
Subscriber Identity. IMEI helps identify the device, whereas IMSI identifies the actual subscriber. It
controls what networks are accessible and also identifies the location of the tablet. Your IMSI number is
stored on your SIM card using a 64 bit field and typically 15 digits in length. In short, IMSI is used on any
and all interconnected networks.

The IMSI sends transmissions from a mobile device to a particular network. To prevent eavesdropping
signals are rarely sent, but in case of emergencies or theft of your device they can prove to be quite
useful. In the majority of cases and for common every day usage a randomly generated signal is sent
What Does Inductive Charging Mean?
Inductive charging is also known as wireless or magnetic charging of a mobile device's battery. It's a
method of wirelessly transmitting energy between electric transformers (usually your tablet PC or
mobile phone) and coils. In other words you can "cut the wire" so to say and still keep your tablet PC
fully charged.

Since 2008 more than 60 firms have joined forces to establish a worldwide wireless power charging
standard. This new universal standard is called Qi and it’s backed by several independent companies. It’s
known as the Wireless Power Consortium, aka WPC. Qi, pronounced as Chi, is a Chinese term which
means “life force” when translated to English. Sounds highly suitable to me.

What Does A-GPS Mean?
A-GPS, also known as assisted global positioning system, comes equipped in tablets and can assist
emergency dispatchers by providing the location of a device. Unlike regular GPS a device with A-GPS has
the ability to transmit signals to and from satellites much better even in areas where signals are not
typically good. In some cases A-GPS is also more efficient since it uses less CPU resources.

What Does HDMI Mean?
HDMI is short for High-Definition Multimedia Interface which is a more advanced way of transmitting
digital data which is uncompressed for both audio and video formats. HDMI technology is still fairly new
having only been around since 2002. Of course it's even newer for tablet PC devices but is on it's way to
becoming quite standard. What makes HDMI so significant is it's high quality, or shall I say high
definition standards.

Now through a single HDMI cable we have the ability to transmit up to 8 channels of digital audio as well
as enhanced 3D video. Such cables can be used for either TVs and also computers such as touch screen
tablets, or slates. It's typically more expensive but the high definition quality of HDMI is nearly second to
none. To date more than 850 PC and consumer electronic manufacturing companies have made the
switch to HDMI and for good reason.

HDMI transmits data much quicker than older digital and analog solutions and supports much higher
resolution devices including but not limited to tablets, HDTV camcorders and digital cameras. It supports
1080p HD video and resolutions of up to 4096×2160p24 with a single 24bit link.

What Does Predictive Text Input Mean?
You may have heard the term Predictive Text Input when the topic of tablet computers or the apps
developed for them comes up. This technology is essentially used to make mobile tablet PCs more
efficient for the people who use them. With predictive text software a user can have an entire word
typed with a single key press, or tap on the touch screen. Instead of sequencing through the same
groups of letters repeatedly it predicts what it is you are attempting to type based on history and/or the
phrase you are entering at any given time.

Such software is known to learn or adapt to the way you write. This is especially useful when texting,
writing letters or emailing, and even filling in your address book or contacts list.

What Does DLNA Mean?
Digital Living Network Alliance, aka DLNA, is a term created and branded by Sony. You may have seen
the term when reading or hearing about their Sony S and Sony P line of tablets. Essentially, DLNA is an
organization founded by Sony which now has more than 250 member companies worldwide that
provide standards-based technology for sharing and consuming media.

With the Sony S tablet for example such technology is used to sync your tablet with your home theater
or digital TV system so you can control operations of such equipment directly from your portable tablet
PC. In other words with DLNA compatible devices your tablet can act as a remote for added

What Does Wi-Fi Hotspot Mean?
Have you ever wondered why that cross-dresser spends so much time, hours upon hours, at your local
coffee shop? Well before you get too creeped out or jump to conclusions, not that there's anything
wrong with cross-dressers of course, consider the fact that they might simply be there to take advantage
of the Wi-fi Internet connection or hotspot that the cafe provides to its customers.

Basically, a Wi-fi hotspot is a place where users can share Internet access which is provided by a router
over a WAN or wireless area network. You tablet computer or mobile smartphone can also double and
act as a hotspot, if they are equipped to do so, and provide online access to other devices nearby.

What Does Capacitive Touchscreen Mean?
When it comes to mobile devices such as tablets there are 2 kinds of touchscreen displays, capacitive
and resistive. Relying on the electrical properties of the human body, primarily through the touch of our
fingers, capacitive screens can detect when a person touches such a display and where exactly they are

A capacitive touch screen consists of a transparent metallic conductive coating. There is a printed
electrode pattern above the conductive layer which distributes a low voltage field. These sensors are
extremely sensitive meaning you barely have to touch the screen in order for it to detect any point or
points of contact.

Tablet computers use multi-touch capacitive screens which can simultaneously detect multiple touch
points at any given time which makes them quite interactive devices, which is part of the reason they
have become such great tools for learning.
What Does Resistive Touchscreen Mean?
Resistive touchscreens are designed using two thin sheets which are separated by air gaps or microdots
and use pressure in order to register the location of contact. Both layers are coated with a resistive
material known as ITO (Indium Tin Oxide). Once the two sheets are pressed together the table senses or
registers a touch in that location.

Typically, resistive touchscreens are used with a style however your finger or any pen like object will also
work just fine most of the time.

Resistive touchscreens are much cheaper to make than capacitive touchscreens why is why the are
commonly found in lower end tablet PCs.

What Does PPI Mean?
Pixels per inch or PPI refers to the pixel density or resolution of a screen display. The higher the PPI is on
a mobile tablet device the better the quality of text and graphics will be.

When it comes to tablet computers PPI aka dots per inch is measured based on the amount of pixels per
inch in relation to the display size. The total number of pixels in both vertical and horizontal directions
will determine overall PPI.

What Is Retina Display
Retina Display boils down to pixel density, also known as resolution. Studies show that the human eye is
capable of clearly viewing roughly 300 pixels per inch. Basically, higher resolution results in higher
quality, more realistic and smoother looking text and images on a display screen.

Even today’s best touch screen tablets on the market with the most advanced displays fall under the 200
pixels per inch (PPI) range. The 7″ Galaxy Tab for example has a resolution of 600×1024 and 171 PPI. The
Galaxy Tab 10.1 has 149 PPI with a resolution of 800×1280.

The 3.5″ Apple iPhone 4 has 640×960 resolution and 326 PPI. Getting such screen technology to work on
smartphones is one thing however and matching that resolution on a larger capacitive touch screen
tablet is a whole new challenge. Thus the reason for the delay of a retina display tablet.

What Does API Mean?
API is an acronym for Application-Programming Interface. This is not to be confused with UI (user
interface) and is better defined as a software-to-software interface. This consists of a standard set of
programming instructions which grants developers access to what is known as a web tool or web based
software application.
As far as tablets are concerned a good example would be the Android OS API. When a new operating
system is released it's necessary for developers to have access to the proper tools and API's available in
order to create custom applications for that particular OS.

In order for developers to create custom apps for Android based tablets, Google released a collection of
Android tablet API's. This has enabled programmers to develop plenty of innovative new Android
applications. A few examples of what is primarily included with such API's are access to:


Java libraries

Database development tools

Background services

UMTS technologies

Key applications

Graphical user interface tools

Content management tools

Tools to manage content and set alarms

...just to name a few.

What Does BlackBerry Bridge Mean?
The BlackBerry Bridge is a term used for syncing data in real-time between your BlackBerry Smartphone
and PlayBook tablet over a wireless connection. This includes cross-platform access to items such as
calendars, eMail, files and contacts.

With BlackBerry Bridge software you can also use your smartphone to access the Internet from your
PlayBook. This is done using your existing cellular data plan.

What Is Cloud Computing?
Cloud computing is a term used to describe the ability to access applications as well as data remotely
from numerous different platforms. In other words you can store something from your MAC or PC for
example on a cloud based server and access it from anywhere in the world from another device such as
a tablet computer so long as you have an Internet connection. This helps reduce the need for additional
hard drive space while keeping your data synced from one device to the next.
What Does LTE Mean?
LTE is an acronym for Long Term Evolution. You may have heard the term "4G Tablet", which essentially
is the same as LTE. Whether you call it 4G, LTE, or fourth generation, these are all terms referring to the
same thing. It's a specific type of technology or wireless broadband which is designed to support
roaming Internet access for portable tablets or other handheld devices such as smartphones.

Monthly plans for LTE are more expansive but also a lot quicker than typical wireless connections. How
quick exactly? Well, trials have shown that LTE connections support download speeds exceeding 300
Mbps. Mind you, it's likely that carriers will not allow customers to obtain such speeds, meaning there
will still be bandwidth caps put in place.

What Does OEM Mean?
OEM stands for Original Equipment Manufacturer. For example, a company that has their own custom
tablet may not necessarily manufacture all of the parts that make the final product. In a lot of cases
companies will outsource to OEM's in order to have certain components mass produced yet still own the
rights to the final product and can retail and brand their tablet pc however they desire.

What Does S/MIME Mean?
The actual meaning of S/MIME is Secure/Multipurpose Internet Mail Extensions. It's a way for people to
send/receive more secure and encrypted eMail messages using what's known as a public key signature.
In order to view S/MIME eMails on your tablet computer you need to have an S/MIME enabled eMail
client or app.

What Does Tethering Mean?
If you have the proper software installed you can use your smartphone as a mobile hotspot. Say for
example you have a Wi-Fi only tablet, you are out in public and have no Internet access. You can tether
(share) your connection from your smartphone to gain the access you require on your portable tablet.
This can also be done using Bluetooth or a direct USB cable.

What Does Qi Mean?
Qi is the official universal standard for wireless power charging. An example would be <a
charged</a> devices which most likely will include tablet computers in the very near future. It's already
being used for Smartphones so it's just a matter of time before tablets are compatible with Qi
technology as well.
What Does Rooting Mean?
Rooting is the method of obtaining full administrative privileges and root access to the Android OS.
Recently I explained <a href="http://www.letstalktablets.com/samsung-galaxy-tab-10-1-tips-and-tricks-
part-1/">how to root the Galaxy Tab 10.1</a>, and also pointed out that Android tablets are not rooted
unless done so by the owner of the device. Android tablets do not come packaged this way, and by
rooting your device you do void any warranty you might have had, but there are in fact many
advantages to doing this.

What Does Jailbreaking Mean?
Jailbreaking iOS devices such as the iPad and iPad 2 is quite similar to rooting except in this case it's
referring to Apple related products. Jailbreaking basically gives you full root access and allows you to
unlock features that otherwise would not be accessible. This ultimately gives you much more control
over the performance of your tablet and what applications can be installed without requiring permission
from Apple to do so.
