Bada OS is a proprietary operating system for smartphones, developed by Samsung and presented in 2009. The first Bada phone – the Samsung Wave – was launched later on, in 2010.
Samsung uses Bada OS alongside Android OS and Windows Phone, but in 2012 the development of new smartphones using Bada has been quietly halted in favor of the more popular Android OS.
Samsung markets all Bada devices under the Wave brand name; similar to how all of their Android-powered devices are branded under the Galaxy name.
A specific range of frequencies (for example those between 1850 MHz and 1995 MHz) are called a band
Bandwidth is used to measure the data throughput of a channel or connection. It’s the amount of data that can be sent over a connection in a given amount of time without distortion. It should not be confused with band.
The bar form factor is the most common and simple form factor for a mobile phone. The body of a bar phone is one, single block and has no moving parts (aside from the buttons). “Locking” the keyboard is done to prevent accidental key presses when the phone is carried in a pocket, purse, etc.
A fixed station that uses radio waves to communicate with mobile devices. It serves as the link between the user’s device and the carrier’s network.
Base stations range in size and area of coverage. Some may cover a radius of several kilometers while others cover only a few city blocks. Most stations transmit in all directions but there are also directional antennas aimed at a specific direction.
Usually base stations are owned by a single carrier but may offer roaming coverage for other networks.
Basemark OS II is a system-level all-in-one benchmarking tool designed for measuring overall performance of smartphones and tablets from all platforms, including Android, iOS and Windows phone 8.
Basemark X is a popular benchmarking tool for evaluation and cross-platform comparison of gaming and graphics performance between Android, iOS and Windows Phone 8 smartphone and tablets.
A binary digit. The values of a bit are either “0” or “1”. Eight bits form a byte.
BlackBerry OS is a proprietary mobile operating system developed by Research In Motion (RIM) for its BlackBerry line of smartphones.
The BlackBerry platform is perhaps best known for its native support for the corporate communication environment, which allows complete wireless activation and synchronization of email, calendar, tasks, notes, and contacts.
Currently deployed versions include the BlackBerry Device Software v5.0, the BlackBerry 6 OS, and the BlackBerry 7 OS.
BlackBerry 10 OS is a QNX-based operating system, similar to the one found on RIM’s Playbook tablet. It will replace the BlackBerry OS on smartphones and tablets in 2013. Details are yet to be disclosed.
BlackBerry Playbook OS
The BlackBerry Playbook OS was developed by Research in Motion (RIM) for its Playbook tablet. It was based on the QNX Neutrino real-time operating system designed to run Adobe AIR and BlackBerry WebWorks applications.
The OS has been received really well by reviewers worldwide despite the lacking features in the original release. Later on, most of these have been added and the OS even got a native Android app launcher (though app support is rather limited).
The Playbook OS is no considered an evolutionary dead-end as no new generation of tablets have been released by RIM.
However, RIM’s latest endeavor – the BlackBerry 10 OS – is similarly based on QNX and it will replace the long-standing BlackBerry OS on smartphones in 2013.
Bluetooth is a wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks.
There are two important parameters of Bluetooth devices – class and supported profiles.
“Class” signifies the distance at which a Bluetooth connection is possible. Most mobile devices are Class 2, which means they have a range of up to 10 m. Class 1 devices are rare and have a range of up to 100 feet.
A “profile” is a type of Bluetooth connection. The most common are the Headset (HSP) and Handsfree (HFP) profiles that enable the device to connect to a wireless headset or handsfree.
Some other profiles are OBEX (OBject EXchange) which allows transfer of files, contacts and events; A2DP, which adds support for streaming of stereo sound and AVRC, which allows remote control of playback.
bps (Bits per Second)
A measure of data transmission speeds, the amount of bits transferred in a single second. Typically, speeds are measured in kbps (1000 bits per second).
Note: kBps (with a capital B) denotes bytes per second.
Not necessarily the same thing as a manufacturer, as most carriers do not fabricate their own devices, but rather acquire them from manufacturers and sell them under their own brand. This is called re-branding.
In data communications, a “broadband connection” is a connection with a high speed of data transfer (greater than 56 kbps). Generally, it is fast enough to support streaming video.
A piece of software that allows the user to access Internet sites.
Most current handsets are equipped with browsers capable of viewing common websites (those intended for a desktop browser).
Web browsers on budget cellphones may be capable of viewing only websites specially made for mobile devices. The most advanced devices currently have web browsers with full Flash support that allows them to play even embedded Flash video (such as the videos from YouTube).
A string of 8 bits.
Typically, one byte equals one character of text but in some cases (especially with non-Latin alphabets), two or more bytes are used. Because of this, an SMS written in Cyrillic or Chinese alphabets has shorter maximum length than one written in the Latin alphabet.
