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 instead. 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 convenience. 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 touching. 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: Middleware 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 href="http://www.letstalktablets.com/will-future-tablets-be-inductively-charged/">inductively 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.
