What are the different types of LED available?
LEDs (Light emitting diodes) are very widely used in today's electronics equipment and they are ruling the world's display technologies today. LED's are used for much electronic equipment. Mostly they are used as panel indicators on televisions, radios and other domestic electronic and industrial equipment. There are different types of LEDs.Traditional inorganic LEDs − These are used for small LED lamps, panel indicators etc.,High brightness LEDs − These are used for domestic lighting.Organic LEDs − Organic LEDs uses organic materials and are replacing the traditional types of LEDs with increased efficiency.

Read MoreWhat is a Nonce in Block Chain?
Cryptocurrency like Bitcoin uses the Block chain as a decentralized, distributed, public digital ledger that records all the transactions of the Bitcoin. Block Chain has a unique feature of storing the value of previous block as a hash value in the current block, which makes it impossible to alter any block without changing all the subsequent blocks.The miners create a block and verify it and will be rewarded for using their CPU power to do so. The block which gets more than 50% consensus will be added to the block chain. During the verification of Block, the miners will complete ...
Read MoreWhat are Orphan Blocks?
Block Chain is the most important component of any cryptocurrency network. Cryptocurrency is based on distributed, transparent public ledger where all the transactions ever made on a cryptocurrency are noted in the blocks and added to the block chain. Miners get attractive rewards to verify and create a new block and add it successfully to the Block Chain.Here comes the twist. There will be some blocks which are created, but not accepted by the block chain network. There are called Orphan Blocks. Orphan blocks are verified and valid blocks, but not accepted by the block chain network due to a ...
Read MoreWhat are Smart Contracts?
Cryptocurrency is entirely dependent on Block Chains to maintain their transactions. A block is like a page of a ledger book where some transactions are written in ink, permanent which cannot be altered. A block typically consists of transactions of bitcoin or any other cryptocurrency and the details of transactions - who has sent, who has received, timestamp and previous blocks information to link it to the Block chain. This information is passed through a hashing algorithm like SHA 256 and creates a 32-bit hash value. This hash value is irreversible.Thus a block is a permanent store of records, which ...
Read MoreWhat is Ethereum?
Before we talk about Ethereum let us first understand the concept of Decentralized network of Bitcoin which laid the foundation for the following Decentralized networks. Bitcoin digital currency was invented by Satoshi Nakamoto in 2009 as using a decentralized and transparent network.Bitcoin uses Cryptography + Proof of work + Decentralized network architecture together. The algorithm of Bitcoins is written in “Turing Incomplete” language, which understands only a limited set of orders like, who has sent the money, how much and who received it.While Bitcoin aims to remove a centralized authority to create the currency, Ethereum uses the Block Chain to ...
Read MoreHow secure bitcoin currency is?

Transactions are recorded in public, distributed ledger turn it more transparent and makes it even harder to temper it.However, cryptocurrency transactions and Blockchain ledgers do have a few security flaws, but they are not essentially the fault of the underlying technology. The structure of Bitcoin and its Blockchain means there are facets ...
Read MoreHow to Mine Ethereum?
Ethereum Mining GuideEthereum Blockchain BasicsAs we all know, cryptocurrency mining is a process of solving complicated mathematical puzzles and miners play a crucial role in any cryptocurrency network as they spend their time and computing power to puzzle out those math problems, giving a ‘proof of work’ for the network, which verifies Ether transactions. Other than this, miners are responsible for making new Ether tokens through this process. This way, they get rewards in Ether for successfully completing a proof of work task.The more miners join the group, the puzzles automatically turn out more difficult to solve. This leads to ...
