Processor:The term processor is used interchangeably with the term central processing unit (CPU), although strictly speaking, the CPU is not the only processor in a computer. The GPU (graphics processing unit) is the most notable example but the hard drive and other devices within a computer also perform some processing independently. Nevertheless, the term processor is generally understood to mean the CPU.
Processor clock:The clock rate typically refers to the frequency at which a chip like a central processing unit (CPU), one core of a multi-core processor, is running and is used as an indicator of the processors speed. It is measured in clock cycles per second or its equivalent, the SI unit hertz (Hz). The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), but in the 21st century the speed of modern CPUs is commonly advertised in GigaHertz (GHz). This metric is most useful when comparing processors within the same family, holding constant other features that may impact performance. Video card and CPU manufacturers commonly select their highest performing units from a manufacturing batch and set their maximum clock rate higher, fetching a higher price.
Number of cores:A multi-core processor is a single computing component with two or more independent actual processing units (called "cores"), which are units that read and execute program instructions. The instructions are ordinary CPU instructions (such as add, move data, and branch), but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing. Manufacturers typically integrate the cores onto a single integrated circuit die (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.

Digital zoom:Some cameras offer a digital zoom, which is simply some in-camera image processing. When you use a digital zoom, the camera enlarges the image area at the center of the frame and trims away the outside edges of the picture. The result is the same as when you open an image in your photo-editing program, crop away the edges of the picture, and then enlarge the remaining portion of the photo.

Sensors Lenovo K2
Accelerometer:An accelerometer is an electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations.
Proximity:A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensors target. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor always requires a metal target.
Magnetometer:The magnetometer sensor in your tablet or smartphone also utilizes the modern solid state technology to create a miniature Hall-effect sensor that detects the Earths magnetic field along three perpendicular axes X, Y and Z. The Hall-effect sensor produces voltage which is proportional to the strength and polarity of the magnetic field along the axis each sensor is directed. The sensed voltage is converted to digital signal representing the magnetic field intensity. Other technologies used for magnetometer may include magneto resistive devices which change the measured resistance based on changes in the magnetic field.
Gyroscope:A gyroscope is a device with a spinning disc or wheel mechanism that harnesses the principle of conservation of angular momentum: the tendency for the spin of a system to remain constant unless subjected to external torque.
Gravity:Gravity sensor is an accelerometer. An accelerometer is a device that measures proper acceleration ("g-force"). Proper acceleration is not the same as coordinate acceleration (rate of change of velocity). For example, an accelerometer at rest on the surface of the Earth will measure an acceleration g= 9.81 m/s2 straight upwards. By contrast, accelerometers in free fall orbiting and accelerating due to the gravity of Earth will measure zero
Hall-effect:A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications.
Fingerprint scanner:A fingerprint scanner is a type of technology that identifies and authenticates the fingerprints of an individual in order to grant or deny access to a computer system or a physical facility.
Data transfer Lenovo K2
xHTML:As the World Wide Web Consortium (W3C) describes it, XHTML (Extensible Hypertext Markup Language) is a reformulation of HTML 4.0 as an application of the Extensible Markup Language (XML). For readers unacquainted with either term, HTML is the set of codes (that is the "markup language") that a writer puts into a document to make it displayable on the World Wide Web. HTML 4 is the current version of it. XML is a structured set of rules for how one might define any kind of data to be shared on the Web. It is called an "extensible" markup language because anyone can invent a particular set of markup for a particular purpose and as long as everyone uses it (the writer and an application program at the receiver is end), it can be adapted and used for many purposes - including, as it happens, describing the appearance of a Web page. That being the case, it seemed desirable to reframe HTML in terms of XML. The result is XHTML, a particular application of XML for "expressing" Web pages.
WAP:WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet access, including e-mail, the World Wide Web, newsgroups, and instant messaging. While Internet access has been possible in the past, different manufacturers have used different technologies. In the future, devices and service systems that use WAP will be able to interoperate.
HSDPA:HSDPA (High-Speed Downlink Packet Access) is a packet-based mobile telephony protocol used in 3G UMTS radio networks to increase data capacity and speed up transfer rates. HSDPA, which evolved from the WCDMA standard, provides download speeds at least five times faster than earlier versions of UMTS, allowing users of HSDPA networks a broader selection of video and music downloads. HSPDA specifies data transfer speeds of up to 14.4 Mbps per cell for downloads and 2 Mbps per cell for uploads. In practice, users are more likely to experience throughput speeds of 400-700 Kbps, with bursts of up to 1 Mbps.
HSUPA:HSUPA stands for high-speed uplink packet access, and is an upgrade to UMTS that allows for uplink connections as fast as 5.76Mbps. HSUPA is similar to EV-DO Rev A in that it can be added to existing networks to increase upload speeds from compatible devices.
HSPA:The term HSPA (High Speed Packet Access) is commonly used to refer to UMTS based 3G networks that support both HSDPA and HSUPA data for improved download and upload speeds. HSPA can also be used to refer to the entire family of related systems, which includes the upcoming HSPA+.
GPRS:General packet radio service, or GPRS, is a wireless data service that enables you send information across a mobile phone network. It is used for second- and third-generation mobile phones for multi-media messaging, Internet access and various applications.
EDGE:EDGE is a data system used on top of GSM networks that provides faster data speeds than GPRS, the technology it makes obsolete. It has a theoretical maximum downlink data rate of nearly 475Kbps, which qualifies it as a 3G technology based on ITU guidelines, even if typical implementations are configured for non-3G speeds. Generally, it is referred to as 2.75G.
Bluetooth:Bluetooth first appeared as a consumer technology in 2000 and it is still going strong. It is a wireless communication protocol for connecting devices through the air - it is slower than Wi-Fi but is often simpler to set up, and is usually preferred for device-to-device transfers.
A2DP Profile:A2DP (Advanced Audio Distribution Profile) is a technology allowing stereo sound to be streamed via Bluetooth from any audio source (mobile phone, PC or laptop) to a stereo speaker or headset. To do so both the source and the speaker need to support this profile.
WiFi:Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x.

Hotspot WiFi:A hotspot is a physical location where people may obtain Internet access, typically using Wi-Fi technology, via a wireless local area network (WLAN) using a router connected to an internet service provider.
USB:USB (Universal Serial Bus) is the most popular connection used to connect a computer to devices such as digital cameras, printers, scanners, and external hard drives. USB is a cross-platform technology that is supported by most of the major operating systems. On Windows, it can be used with Windows 98 and higher. USB is a hot-swappable technology, meaning that USB devices can be added and removed without having to restart the computer. USB is also “plug and play”. When you connect a USB device to your PC, Windows should detect the device and even install the drivers needed to use it.
GPS module:A GPS navigation device or GPS receiver, and when used for vehicle navigation commonly referred to simply as a GPS, is a device that is capable of receiving information from GPS satellites and then to accurately calculate its geographical location. The Global Positioning System (GPS) is a global navigation satellite system (GNSS) made up of a network of a minimum of 24, but currently 30, satellites placed into orbit by the U.S. Department of Defense.
A-GPS:A-GPS augments that by using cell tower data to enhance quality and precision when in poor satellite signal conditions. In exceptionally poor signal conditions, for example in urban areas, satellite signals may exhibit multipath propagation where signals skip off structures, or are weakened by meteorological conditions or tree canopy. Some standalone GPS navigators used in poor conditions can not fix a position because of satellite signal fracture, and must wait for better satellite reception. A GPS unit may need as long as 12.5 minutes (the time needed to download the GPS almanac and ephemerides) to resolve the problem and be able to provide a correct location.
NFC:NFC is something you may often hear mentioned with regard to new smartphones, but it is something which few people have an understanding of, or even use. Yes, it's an acronym, but not all acronyms have to be scary. NFC is both easy to understand and can be incredibly useful. Here's all you need to know about what NFC is and why you should use it.
