(Use of Snapdragon in Androids)

By Utkarsh

Hello everyone, today after many months, I will be trying my best to make you understand, what is snapdragon. But before I just start exploding on the topic, let's understand, what is qualcomm?

Qualcomm is an American MNC, headquartered in San Diego, California and is incorporated in Delaware. It is the company  which creates semiconductors, softwares and other services related to wireless technology. The various products of Qualcomm are CDMA/WCDMA chipsets, Snapdragon, BREW, OmniTRACS, MediaFLO, QChat, mirasol displays, uiOne, Gobi, Qizx, CPU. And here, we will be focusing upon Snapdragon. So let's begin.

Snapdragon is a suite of system on chip (SoC) semiconductor products for mobile, tablets, and smartbook devices designed and marketed by Qualcomm Technologies Inclusive. Basically, Snapdragon is kind of a processor or say it's a CPU (Central Processing Unit) that uses ARM architecture. ARM processors are one of a family of CPUs based on the RISC (Reduced Instruction Set Computer) developed by ARM (Advanced RISC Machines).

Currently, there are many companies, responsible for creating mobile processors. Some of them are as follows: Apple Bionic SoC, Qualcomm Snapdragon SoC, Samsung Exynos SoC, MediaTek SoC, HiSilicon Kirin SoC, etc.

Qualcomm Snapdragon mobile platforms are designed to be fast, intelligent, smooth and secure with amazing graphics. These processors with multi core CPU with extra ordinary features and support for worldwide network connectivity with jaw-dropping speeds and unbelievable power efficiency.

Smartphones and mobile devices built with Snapdragon mobile platforms enable immersive AR (augmented reality) with VR (Virtual Reality) experiences, brilliant camera capabilities, superior 4G LTE and 5G connectivity, and the latest security solutions.

Snapdragon semiconductors are embedded in devices of various systems like android, windows, iPhones and netbooks. They are also used in cars, wearable devices and other devices. In addition to the processors, it includes modems, Wifi chips and mobile charging products.

There are various mobile phone companies that uses Snapdragon processors, some of them are Asus, iQOO, Lenovo, OnePlus, OPPO, Realme, Samsung, Sony, Vivo, Xiaomi, etc.

The role of technology in education is that technology provides students with easy-to-access information, accelerated learning, and fun opportunities to practice what they learn. It enables students to explore new subjects and deepen their understanding of difficult concepts, particularly in 'STEM'.

'STEM' stands for Science, Technology, Engineering and Mathematics but it;s more than that. STEM has grown to represent a unique approach to teaching and learning, one that centers around individual students' learning styles and interests. This means STEM education has something to offer every student.

Qualcomm has its passive effect on education by contributing into the devices for modern learning. With the growth of hybrid learning, educators and students need the flexibility to teach and learn anywhere, whether they are remote or in the classroom. Snapdragon powered laptops can provide a reliable, always connected solution with incredible battery life, enterprise-grade security and modern device management. Now administrators and parents can remain flexible, empowering students and teachers virtually anywhere.

Thank you.

CRYPTOCURRENCY

 CRYPTOCURRENCY

What Cryptocurrency is coined of 2 terms, Crypto and currency. Crypto means hidden or secret while currency is a system of money, generally used by the individual country. A cryptocurrency often termed as crypto currency or crypto for short, is a digital asset designed to work as a medium of exchange wherein individual coin ownership records are stored in a ledger existing in a form of computerized database using strong cryptography to secure transaction records or to control the creation of additional coins, and to verify the transfer of coin ownership. It does not exist is physical form or paper money and is also not issued by any central authority. Crypto currency generally use decentralized control as opposed to centralized digital currency and central banking system. Since it's decentralized control, thus, it works on distributed ledger technology, typically a blockchain, that serves as public financial transaction database. Every new transaction data is saved in form of a block on computers connected to same network and every new data block is chained with the previous block. Why The main reason why cryptocurrency has any value is Blockchain,why one should use it is it's ease-of-use. All you need is a smart device, an internet connection and instantly you become your own bank making payments and money transfers and performing everything which a bank can. When and Where Cryptocurrency was first developed as an electronic money but in centralized control by an American cryptographer, David Chaum in 1983 which he used to call ecash. Later in 1995, he implented this electronic money through his corporation Digicash for next three years at in 1998, Digicash was declared bankruptcy and sold its assets. Many more attempts were made to create crypto(s) since then but all of them were centralized. It was only Bitcoin which was first decentralized cryptocurrency developed in 2009 by presumably pseudonymous developer, Santoshi Nakamato which can be an individual or possibly a group of programmers. There are numerous types of crypto(s) available such as: Bitcoin or BTC, Litecoin or LTC, ETH, ZEC, XLM,etc. All of them combined known as altcoins. Most of the bitcoins uses SHA-256 hashing algorithm How Crytocurrency can be used through cryptocurrency wallets which provides you public and private keys or addresses for recieving and spending cryptos respectively. Minning For crypto(s), Mining is a validation of transactions as for successful miners, they receive a cryptocurrency as a reward thus decreasing transaction fee for the particular miner. A cryptocurreny Miner is basically a Supercomputer with even more powers and modified specifications to help it with faster hashing and problem solving, authenticating and storing consumer data in encrypted formats. Miners require some additional electronic machines such as FGPAs (Field Programmable Gate Arrays) and ASIC (Application Specific Integrated Circuits). Both, a supercomputer and a miner requires high amount of power but the units for power consumption for supercomputers like PARAM Yuva,Sidhi or Tianhe 1-A uses electricity ranging from 1 MW to 4 MW per second while Miners requires 120 GW to 63 TW per second. According to a February 2018 report from Fortune, Iceland has become heaven for cryptocurrency miners in part because of its cheap electricity. According to reports of 2019, alone Bitcoin Miners power consumption was of 0.02% of global consumption which is equivalent to Switzerland's power consumption; Now you can have a rough idea as there are various crypto miners. In March 2018, the city of Plattsburg in upstate New York put an 18-months moroatorium or legal delay on all crypo miners in an effort to preserve natural resources

Arduino Project #1 Experience

Automatic Irrigation System – AIS

By: Utkarsh

Hello everyone, today I will be discussing about one of my project which is as simple as thinking but is useful too. As days are passing by, water scarcity and lowering of water resources are increasing, that means we, human beings are not retaining sustainable development and we are blindly converting the useful resources into useless.

Many of you would know, that I had changed my school, which is like interrupting my niche, but now, I am trying to make this new environment my niche, which is equivalent to impossible, however, I had made some friends, and now one of my classmate from X also had arrived in the same school but is floating in different stream.

So, let us come on the topic, for which I am writing this article. I joined the school late in comparison to previous children and so I am running half a month behind the syllabus. Even I can’t believe that how had I not completed my pending works even after spending holidays of more than a month, which was more than enough for any pending work.

In the month of May, our chemistry teacher told us to make something related to science, like a project! Which I had never tried before, though he suggested us to make a team but again, with whom should I make my team? And after that day, no team was either made nor I joined any of them. Sir had told us to make something which is useful in today’s world, where the global warming is continuously increasing.

This hint with the combination of watering the plants at every evening as per the order of my mother produced an amazing idea, but the problem did not stopped here. This new idea was completely of Computer-Science. Though I am still confused, whether to submit this or not but is very useful for watering the plants or even a large field full of plants and trees.

I made Automated Irrigation System using single on-board computer called, arduino. I programmed it on the basis of C/C++. Tried and tested too. Something which makes me laugh on my project is that, I can see physics in circuits to electricity and magnetic effect in SSR-Relay, nothing else related to Science. May be, the water is part of chemistry as it is the combination of 2 atoms of Hydrogen and 1 atom of Oxygen. This single board computer is capable of converting 12V DC to usable 5V DC.

The programming of the AIS is given below:
