Screen Resolution:The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT), flat-panel display which includes liquid-crystal displays, or projection displays using fixed picture-element (pixel) arrays.

CPU:A mobile processor is found in mobile computers and cellphones. A CPU chip is designed for portable computers, it is typically housed in a smaller chip package, but more importantly, in order to run cooler, it uses lower voltages than its desktop counterpart and has more "sleep mode" capability. A mobile processor can be throttled down to different power levels or sections of the chip can be turned off entirely when not in use. Further, the clock frequency may be stepped down under low processor loads. This stepping down conserves power and prolongs battery life.

Type:
Quad-Core
Frequency:Processor frequency specifies the operating (internal) frequency of CPU core. The higher the frequency is for a given CPU family, the faster the processor is. Processor frequency is not the only parameter that affects system performance. Another parameter than greatly affects the performance is CPU efficiency, that is how many Instructions Per Clock (IPC) the CPU can process. Knowing these two parameters it is easy to calculate total number of instructions per second.

Accelerometer:An accelerometer is a device that measures changes in gravitational acceleration in a device it may be installed in. Accelerometers are used to measure acceleration, tilt and vibration in numerous devices. At rest, an accelerometer measures 1g: the earth is gravitational pull, which registers 9.81 meters per second or 32.185 feet per second. Accelerometers that use the piezoelectric effect measure a small voltage change. Others measure capactitance between two components.

Light sensor:A Light Sensor is something that a robot can use to detect the current ambient light level - i.e. how bright/dark it is. There are a range of different types of light sensors, including Photoresistors, Photodiodes, and Phototransistors. The sensor included in the BOE Shield-Bot kit, and the one we will be using, is called a Phototransistor.

Resolution:The number of megapixels is only one aspect relating to the quality of a camera, or the actual quality of a photo it is capable of producing. Factors such as camera sensor and processor, and the optical quality of a lens, play equally important roles.

Aperture:Simply put, aperture is a hole within a lens, through which light travels into the camera body. It is easier to understand the concept if you just think about our eyes. Every camera that we know of today is designed like human eyes. The cornea in our eyes is like the front element of a lens - it gathers all external light, then bends it and passes it to the iris. Depending on the amount of light, the iris can either expand or shrink, controlling the size of the pupil, which is a hole that lets the light pass further into the eye. The pupil is essentially what we refer to as aperture in photography. The amount of light that enters the retina (which works just like the camera sensor), is limited to the size of the pupil - the larger the pupil, the more light enters the retina.

SIM:The standard SIM card is the original SIM and largest of the three. This SIM measures 25x15mm. The Micro SIM card is essentially a standard SIM card with the extra plastic around the circuit board trimmed off. Micro SIM cards measure 15x12mm. The Nano SIM card is the most recent type of SIM card which only measures 12.3x8.8mm.

Wi-Fi standards:These standards were created by an organization known as the Wi-Fi Alliance, a trade association consisting of companies interested in promoting a common standard for wireless Internet connections. IEEE 802.11 - The original! Created in 1997, this now-defunct standard supported a blazing fast maximum connection speed of megabits per second. Devices using this haven't been made for over a decade and won't work with today's equipment. IEEE 802.11a - Created in 1999, this version of Wi-Fi works on the 5 GHz band. This was done with the hope of encountering less interference, since many devices (like most wireless phones) use the 2.4 GHz band as well. 802.11a is fairly quick too, with maximum data rates topping out at 54 megabits per second. However, the 5GHz frequency has more difficulty with objects that are in the signal's path, so the range is often poor. IEEE 802.11b - Also created in 1999, this standard uses the more typical 2.4 GHz band and can achieve a maximum speed of 11 megabits per second. 802.11b was the standard that kick-started Wi-Fi's popularity. IEEE 802.11g - Designed in 2003, the 802.11g standard upped the maximum data rate to 54 megabits per second while retaining usage of the reliable 2.4 GHz band. This resulted in widespread adoption of the standard. Wireless g remains common even today, as it is adequately fast and routers lacking support of the new n standard are incredibly cheap. IEEE 802.11n - The newest Wi-Fi standard, n was actually introduced in 2009. It's been adopted slowly, but it now common on routers and laptops. 802.11n can operate at both 2.4GHz and 5 GHz and it supports multi-channel usage. Each channel offers a maximum data rate of 150 megabits per second, which means the maximum data rate of the standard is 600 megabits per second. However, this requires hardware support, and I have yet to see a Wireless n router with more than three channels. The support must be on both ends as well, so you can't make use of a dual or tri-channel router if your laptop only supports a single channel.

Bluetooth:Bluetooth is a global wireless communication standard that connects devices together over a certain distance. A Bluetooth device uses radio waves instead of wires or cables to connect to a phone or computer. A Bluetooth product, like a headset or watch, contains a tiny computer chip with a Bluetooth radio and software that makes it easy to connect. When two Bluetooth devices want to talk to each other, they need to pair. Communication between Bluetooth devices happens over short-range, ad hoc networks known as piconets. A piconet is a network of devices connected using Bluetooth technology. The network ranges from two to eight connected devices. When a network is established, one device takes the role of the master while all the other devices act as slaves.

Profiles:
A2DP (Advanced Audio Distribution Profile)The Advanced Audio Distribution Profile is a Bluetooth profile that allows for the wireless transmission of stereo audio from an A2DP source (typically a phone or computer) to an A2DP receiver (a set of Bluetooth headphones or stereo system). Such devices typically also support the AVRCP profile as well in order to allow for track selection and such. A common misconception is that A2DP support is available on all Bluetooth 2.0 devices, which is not the case, and that A2DP is only available on Bluetooth 2.0 devices, which is also not true. A2DP support can exist in older versions of Bluetooth, it just was not commonly supported., AVRCP (Audio/Visual Remote Control Profile), EDR (Enhanced Data Rate), HDP (Health Device Profile), HFP (Hands-Free Profile), HID (Human Interface Profile), MAP (Message Access Profile), OPP (Object Push Profile), PBAP/PAB (Phone Book Access Profile), SPP (Serial Port Protocol)

Tethering.:"Tethering" is the use of your cell phone (or another mobile device that is connected to the internet) as a modem for another device, usually a laptop or a Wi-Fi-only tablet. This gives you internet access on the go, wherever you are. You connect your phone to your laptop or tablet either directly with a USB cable or without wires through Bluetooth or Wi-Fi. (In the good old days, we tethered devices via infrared.)
