Tethering
Tethering or phone-as-modem (PAM) is the sharing of a mobile device's cellular data connection with other connected computers. It effectively turns the transmitting device into a modem to allow others to use its cellular network as a gateway for Internet access. The sharing can be done wirelessly over wireless LAN (Wi-Fi), Bluetooth, IrDA or by physical connection using a cable like USB. If tethering is done over Wi-Fi, the feature may be branded as a personal hotspot or mobile hotspot, and the transmitting mobile device would also act as a portable wireless access point (AP) which may also be protected using a password. Tethering over Bluetooth may use the Personal Area Networking (PAN) profile between paired devices, or alternatively the Dial-Up Networking (DUN) profile where the receiving device virtually dials the cellular network APN, typically using the number ''*99''#. Mobile devices' OS support Many mobile devices are equipped with software to offer tethered Internet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Phone 7
Windows Phone 7 (WP7) is the first release of the Windows Phone mobile client operating system, released worldwide on October 21, 2010, and in the United States on November 8, 2010. It runs on the Windows CE 6.0 kernel. It serves as the successor to Windows Mobile 6.5. Windows Phone 7 was a complete overhaul of Microsoft's previous mobile Windows platforms. It was designed with the distinct flat-styled Metro interface. The first major update to Windows Phone 7 was Windows Phone 7.5, codenamed "Mango", which was globally released on September 27, 2011. Windows Phone 7.x was succeeded by Windows Phone 8, which was released on October 29, 2012; existing Windows Phone 7.x hardware could not upgrade to the incompatible Windows Phone 8 software. As a compromise to existing users, Microsoft released Windows Phone 7.8 on January 31, 2013, adding a few features backported from Windows Phone 8, such as a more customizable start screen and the new bootscreen.

Symbian
Symbian is a discontinued mobile operating system (OS) and computing platform designed for smartphones. It was originally developed as a proprietary software OS for personal digital assistants in 1998 by the Symbian Ltd. consortium. Symbian OS is a descendant of Psion's EPOC, and was released exclusively on ARM processors, although an unreleased x86 port existed. Symbian was used by many major mobile phone brands, like Samsung, Motorola, Sony Ericsson, and above all by Nokia. It was also prevalent in Japan by brands including Fujitsu, Sharp and Mitsubishi. As a pioneer that established the smartphone industry, it was the most popular smartphone OS on a worldwide average until the end of 2010, at a time when smartphones were in limited use, when it was overtaken by iOS and Android. It was notably less popular in North America. The Symbian OS platform is formed of two components: one being the microkernel-based operating system with its associated libraries, and the othe ...

Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs Ultra high frequency, UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones, wireless speakers, HIFI systems, car audio and wireless transmission between TVs and soundbars. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The Institute of Electrical and Electronics Engineers, IEEE standardized Bluetooth as IEEE 802.15.1 but no longer maintains ...

Access Point Name
An Access Point Name (APN) is the name of a gateway between a mobile network (GSM, GPRS, 3G, 4G and 5G) and another computer network A computer network is a collection of communicating computers and other devices, such as printers and smart phones. In order to communicate, the computers and devices must be connected by wired media like copper cables, optical fibers, or b ..., frequently the public Internet. A mobile device making a data connection must be configured with an APN to present to the Wireless carrier, carrier. The carrier will then examine this identifier to determine what type of network connection should be created, for example: which IP addresses should be assigned to the wireless device, which Network security, security methods should be used, and how, or if, the device should be connected to some private customer network. APN settings connect the device to the internet via mobile carrier’s cellular network. These settings include IP addresses, gatew ...

Personal Area Network
A personal area network (PAN) is a computer network for interconnecting electronic devices within an individual person's workspace. A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway. A PAN may be carried over wired interfaces such as USB, but is predominantly carried wirelessly, also called a wireless personal area network (WPAN). A PAN is wirelessly carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth, NearLink or Zigbee. The reach of a WPAN varies from a few centimeters to a few meters. WPANs specifically tailored for low-power operation of the sensors are sometimes also called low-power personal area network (LPPAN) to better distinguish them from low-power wide-ar ...

IOS Jailbreaking
iOS jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by Apple on devices running iOS and iOS-based operating systems. It is typically done through a series of kernel patches. A jailbroken device typically permits root access within the operating system and provides the right to install software unavailable through the App Store. Different devices and versions are exploited with a variety of tools. Apple views jailbreaking as a violation of the end-user license agreement and strongly cautions device owners not to try to achieve root access through the exploitation of vulnerabilities. While sometimes compared to rooting an Android device, jailbreaking bypasses several types of Apple prohibitions for the end-user. Since it includes modifying the operating system (enforced by a "locked bootloader"), installing non-officially approved (not available on the App Store) applications via sideloading, and granting the user elevated adm ...

Rooting (Android OS)
Rooting is the process by which users of Android devices can attain privileged control (known as root access) over various subsystems of the device, usually smartphones and tablets. Because Android is based on a modified version of the Linux kernel, rooting an Android device gives access to administrative (superuser) permissions similar to those on Linux or any other Unix-like operating system such as FreeBSD or macOS. Rooting is often performed to overcome limitations that carriers and hardware manufacturers put on some devices. Thus, rooting allows the users to alter or replace system applications and settings, run specialized applications ("apps") that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. On some devices, rooting can also facilitate the complete removal and replacement of the device's operating system, usually with a more recent release of its current operating system. Root acc ...

IPv4 Network Address
Internet Protocol version 4 (IPv4) is the first version of the Internet Protocol (IP) as a standalone specification. It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production on SATNET in 1982 and on the ARPANET in January 1983. It is still used to route most Internet traffic today, even with the ongoing deployment of Internet Protocol version 6 (IPv6), its successor. IPv4 uses a 32-bit address space which provides 4,294,967,296 (232) unique addresses, but large blocks are reserved for special networking purposes. Purpose The Internet Protocol ("IP") is the protocol that defines and enables internetworking at the internet layer of the Internet Protocol Suite. It gives the Internet a global-scale logical addressing system which allows the routing of IP data packets from a source host to the next router that is one hop closer to the intended destination host ...

Network Address Translation
Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic Router (computing), routing device. The technique was initially used to bypass the need to assign a new address to every host when a network was moved, or when the upstream Internet service provider was replaced but could not route the network's address space. It is a popular and essential tool in conserving global address space in the face of IPv4 address exhaustion. One Internet-routable IP address of a NAT gateway can be used for an entire private network. As network address translation modifies the IP address information in packets, NAT implementations may vary in their specific behavior in various addressing cases and their effect on network traffic. Vendors of equipment containing NAT implementations do not commonly document the specifics of NAT behavior. History Internet ...
