Quantum computing

 Quantum computing Quantum computing is the use of quantum phenomena such as superposition and entanglement to perform computation. Computers that perform quantum computations are known as quantum computers. Quantum computers are believed to be able to solve certain computational problems, such as integer factorization , substantially faster than classical computers. The study of quantum computing is a subfield of quantum information science. Quantum computing began in the early 1980s, when physicist Paul Benioff proposed a quantum mechanical model of the Turing machine. Richard Feynman and Yuri Manin later suggested that a quantum computer had the potential to simulate things that a classical computer could not. In 1994, Peter Shor developed a quantum algorithm for factoring integers that had the potential to decrypt RSA-encrypted communications.Despite ongoing experimental progress since the late 1990s, most researchers believe that "fault-tolerant quantum computing still a rath

What is android

  What is android  Android is a mobile operating system based on a modified version of the Linux kernel and other open source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. It is free and open source software; its source code is known as Android Open Source Project (AOSP) which is primarily licensed under the Apache License. However most Android devices ship with additional proprietary software pre-installed, most notably Google Mobile Services (GMS) which includes core apps such as Google Chrome, the digital distribution platform Google Play and associated Google Play Services development platform. About 70 percent of Android smartphones run Google's ecosystem; competing Android ecosystems and forks include Fire OS (developed by Amazon) or LineageOS. However the "Android" name and logo are trademarks of Google which impose standards to restrict "uncertified" devices outside their ecosystem to use Android branding. T

What is VoLTE ? Voice over-LTE

VoLTE full meaning Voice over Long Term Evolution Voice over LTE (VoLTE) means better sound voice calls quality and the able to use voice and data at same time, you should know about VoLTE wireless network technology. VoLTE is 4th Generation Wireless data transmission technology.   What are the benefits of VoLTE? The implementation of VoLTE offers many benefits, both in terms of cost and operation. VoLTE: Eliminates the need to have Voice on one network and data on another Provides more efficient use of spectrum than traditional Voice Delivers an unusually crisp calling experience Meets the rising demand for ‘Richer’, more reliable services including video share, multimedia messaging, chat and file transfer Unlocks new revenue potential, utilising IMS as the common service platform Can be deployed in parallel with video calls over LTE and RCS multimedia services,  Increases handset battery life by 40 per cent (compared with VoIP) Provides rapid call establishment time

What is 5G What is 4G . How difference Between 4G and 5G

What is 5G What is 4G . How difference Between 4G and 5G  5G is the fifth generation technology standard for cellular networks. 5th generation wireless system, abbreviated to 5G , is a state-of-the-art wireless network that will be rolled out in 2018 and beyond. (GB/s) capable of providing speed; Large range MIMO (Multiple Input Multiple Output - 64-257 Antenna) which is capable of providing "minimum 10 times performance of 4G ", "Low-band 5G" and "Mid-band 5G", 600 MHz to 6 GHz, especially 3 .5-4.2 GHz waves are used. 3 GPP The general definition of 5G has been determined through release 15 of December, 2017. Many prefer ITU's IMT-2020 definition, which refers to the use of high frequency bands for higher speeds.The millimeter wave system is designed to achieve a maximum download speed of 20 GB/s. They have an average speed of 3.5 GB/s. With the extra large MIMO antenna, the approximate median bandwidth of the 3.5-4.2 GHz band is 490 MB per second. I

The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called cellular teleph
