Blockchain had its big breakthrough with Bitcoin in 2009. When blockchain comes up, most people start thinking about Bitcoin and cryptocurrencies, but it is a broad technology for handling information that can be used for almost anything. Many believe that blockchain will lead to a revolution and break through on a broad front throughout society. How blockchain works To explain blockchain, it is easiest to start from how everything works today. Let's say you buy a product online. Lots of different parties are involved. First of all, there is a factory where the product is manufactured. Then there may be various intermediaries and of course the retailer from whom you bought the product. In addition, one or more banks and freight companies are also involved. All these players have thei...

How does an antenna work? The electromagnetic waves drive current from one end of the antenna to the other. The efficiency of an antenna depends on the length of the antenna in relation to the wavelength of the electromagnetic waves to be received. An antenna on a transistor radio is between 10 and 20 centimeters when inserted. If it sounds bad, pull it out so that it is up to one meter long and approach the most effective length of an antenna - one and a half meters. An antenna that has one end in a wave crest and the other in the wave valley in the middle between the wave crests is more efficient. Making the antenna several wavelengths long does not increase efficiency, there will only be more areas within which current can swing back and forth. For a transmitting antenna...

Electricity is already sent wirelessly in electric toothbrushes and kettles. Now the power must be sent over greater distances so that your computer and TV can also avoid cables. In this article, we are looking closer at how wireless electricity works and what it is. Even now, electricity can be sent wirelessly, but only over short distances. This happens, for example, in electric toothbrushes, where a copper coil in the charger converts electricity into a magnetic field. The magnetic field is captured by a copper coil in the toothbrush, whereupon the field is converted into electricity again. The problem is that the energy is lost if the distance between the coils is too large. Electricity moves wirelessly through the air However, a new way of using the technology means tha...

An IP address is a number that identifies an Internet connection. They are used as the network's own system of addresses and the purpose is for information sent to reach the correct recipient. If your computer is connected to the internet, it will have an IP address. Where can I find my IP address? If you want to know your IP address, there are smart services online that offer IP address lookup. It's no harder than visiting a site like whatismyipaddress.com or www.whatsmyip.org to find out the IP address that currently identifies you. For private individuals, this usually depends on the choice of Internet operator. Usually, they assign dynamic IP addresses provided by the ISP server. They change at each connection, unlike static IP addresses which retain the same fixed address at all...

No more tangled cables and cluttered charging stations. Wireless charging is taking the world by storm and the technology is growing greatly. Even though more and more manufacturers support wireless charging, there is still a long way to go before this technology replaces the "old way" of charging. With the iPhone 8, iPhone 8 Plus and iPhone X, the tech giant Apple launched its first phones with the option of wireless charging. In addition, a separate charging surface was designed to charge several devices simultaneously. Before that, it was mainly Nokia and Samsung that embraced this technology, and they already have more models on the market that are compatible with wireless chargers. This is how wireless charging works Wireless: Induction charging works with the help of t...
