How Does Crypto-technology Work ?

  If truth be told, in order to understand this, one needs to have knowledge of advanced mathematics and computer science . But if you want to start investment or trading, then basic knowledge would suffice .       Let us take the example of Bitcoins There is one public account in digital form, of all the bitcoin transactions this is called a 'ledger' . A copy of this ledger exists on all the systems that are a part of the Bitcoin network Those that run this system are called 'Miners' The job of the miners is to verify transactions Say, A has to transfer 2 Bitcoins to B's account Miners will have to confirm whether A actually does have 2 Bitcoins in his account or not To complete the transaction, miners will have to solve a complicated mathematical equation You might have studied about variables back in school. Every Bitcoin transaction has a unique variable The job of the miners is to calculate it It's not that they sit with a pen or paper to solve the equation...

Audio

         Audio is another very important component of multimedia, because in many cases sound can substantially reinforce our understanding of information presented in other ways, and in some cases sound is the only way to provide the desired information. In the multimedia application meant for educating small children, voice explanation can be added to the animation clip for describing what is being shown, and pointing out what to look for that makes a horse's gallop different from a horse's walk. Similarly an animation clip can show the horse neighing and neighing sound can be added to effectively convey the type of sound horses make. Analog and Digital Audio:  Audio information travels in natural medium in the form of sound waves, which are analog in nature. For the computer to be able to understand audio information, sound waves must be converted from analog to digital form. Transducer is a device capable of changing signals from one form to another.
