Excessive acronyms and technical terms difficult choosing the right device; find out what each one means
NFC, MHL, dual core, Glonass. This alphabet soup is well known to anyone who ever researched information on a smartphone. Unfortunately, many manufacturers sites have little explanation about the meaning of each acronym or on its usefulness in everyday user. Thinking about it, iG prepared a quick guide that explains the acronyms that appear in more smartphones settings. Check it.
CONFIGURATION
Chip Dual core / quad core / core Octa - these terms refer to the number of processor cores (dual core, dual core, quad core, quad-core, octa core, eight-core). The number of nuclei is indicative of the processing capacity of the chip but not the only one.
RAM - is the memory used to run the applications and, with the processor, is what makes the device faster. The values range from 512 MB for basic appliances up to 3 GB on top of the line appliances.
Storage - is the memory used to install applications and store music, videos and other file types. On 4 GB basic smartphones up to 128 GB and advanced models.
From left to right: SIM cards, Micro-SIM and Nano-SIM
YES / MicroSIM / nanosim - are the types of mobile operator's SIM card in the market. The SIM is the largest size used in basic cell and most of the smart phones that support two or more chips. The MicroSIM is increasingly common intermediate smartphones and the top line. Some devices use even smaller chip, the nanosim.
GPS / GLONASS - GPS is a global navigation satellite system mainly used in map applications and traffic initially developed by the US government. Some smartphones also support GLONASS system, which is nothing more than an alternative to GPS created by Russia.
CONNECTIONS
Edge / 3G / 3.5G / 4G / LTE - are standards used to identify the Internet connection speed. Edge corresponds to 2G, with very low speed. The 3G has real average speed between 1 and 2 Mbps. With 3G + (HSDPA + standard) this speed can reach about 6 Mbps. Already 4G (most common name LTE technical standard) has speed that usually stay at 20 Mbps home.
Wi-Fi b / g / n / ac- Wi-Fi is the wireless standard used for internet access. Most smartphones on the market supports the version n. But some more advanced handsets also work with the ac network, faster. But this speed gain will occur only if the phone is on a wireless network that also runs on ac standard.
Wi-Fi Direct - This feature allows you to transfer content between smartphones through a Wi-Fi network even without a router nearby. The cell equipped with direct Wi-Fi can create your own network and connect to other devices. In practice, the Wi-Fi Direct can replace Bluetooth in certain situations, providing a faster connection (but consuming more battery).
Wi-Fi hotspot - is the feature that lets you use the phone to share the 3G / 4G using a wireless network itself and password set by the other party. Present in all market smartphones.
USB On The Go (OTG) - is a feature that allows the phone to be connected to pen drives, keyboards and other USB peripherals.
NFC (Near-field Communication) - Currently, this technology is used primarily to facilitate communication between your smartphone and accessories like wireless speakers and smart watches. When the user approaches the smarphone compatible equipment NFC module, synchronization occurs instantaneously. After synchronization, another wireless standard (usually Bluetooth) is used for data transfer. The NFC is also used in mobile payment systems, such as Apple Pay.
Bluetooth - technology short-range wire used primarily to connect the phone to headphones and speakers. The latest version, and less battery consumption, is 4.0 LE (Low Energy).
Miracast - technology that allows the smartphone to send audio and video to a TV without the use of wires or Wi-Fi network TV, however, also have to be compatible with Miracast..
DLNA - has basically the same function Miracast but is older and has fallen into disuse.
MHL cable has a tip microUSB format and another in HDMI format
MHL - standard used to send audio and video from a smartphone to a high definition TV. The MHL standard uses the miniUSB port smartphone to send audio and video to a TV. It is necessary, however purchase a MHL cable. This cable has a tip compatible with microUSB (embedded smartphone) and other HDMI tip (fitted on TV).
SCREEN
qHD / HD / Full HD / QuadHD - are acronyms that identify the device's screen resolution. The qHD matches the resolution of 960 x 540, the HD is 1280 x 720; Full HD, 1,920 x 1,080, QuadHD, 2,560 x 1,440.
pixel density - Nothing more than the screen pixel total divided by its area in inches. When we say that a cell is 240 dpi (dots per inch) or 240 dpi (pixel per inch), we are saying that every square inch of the screen comprises 240 pixels. Thus, depending on the resolution cell with the same size screens may have different densities.
IPS (In Plane Switching) - This technology is used to ensure a better image with the sloping cell. It is present in much of the intermediate apparatus and all the most sophisticated models.
Gorilla Glass - Made by the American company Corning, Gorilla Glass is the high-strength glass used to protect the screen of some intermediate and sophisticated smartphones. The most modern and resistant version is Gorilla Glass 3, but version 4 will soon be on the market.
CAMERA
Flash LED - is the type of camera flash that uses an LED light to illuminate the scene. This is the most common type of flash. Some high-end smartphones use xenon flash (Xenon flash), similar to those used in cameras.
optical stabilization - is a set of sensors and small gears which compensate in real time the user blurred, which provides pictures with less blur. Few mobile phones on the market use this technology.
DRUMS
mAh (milli-Ampere-hour) - It is the unit that measures the phone's battery charge capacity and usually get between 2,000 mAh and 3.000mAh. As each cell has a different power consumption, duration of a single battery may vary.
