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...

There are several things to keep in mind before mounting your TV on the wall. In this post, we will go through the most important things you need to know - height, angle, mount and distance. Where should your TV be placed? The first question you should ask yourself is where the TV should sit. Depending on the design of the room, it is sometimes better to leave the TV on a stand, while it is sometimes nicer to mount it on the wall, but often it simply has to do with your personal preference. Here are a few important aspects to keep in mind: How high or low should the TV sit? The rule of thumb is that the TV, when watches from the couched, must be mounted at a viewing angle of about 30 degrees. This means that a TV should be mounted about as high as it is in inches. In other w...

A dimmer works so that it pulses out current to the lamp. Each time the current drops to zero, ie when the alternating current changes direction. (50Hz AC passes through the zero point 100 times per second, once up once and once down for each period then the dimmer restricts the current so that it remains zero for a moment, how long is determined by how much you dim. Then the dimmer releases at full power for the rest of the period. This is repeated for each of the 100 periods every second. The finesse of this is that as long as the current is throttled to zero, there will also be no power loss (power P = U x I, I is zero, the power will be zero). And when the dimmer opens fully, current flows through the dimmer, but then the voltage across the dimmer is zero (or almost 0), the e...

Phishing is one of the most common methods of attack among cybercriminals today. The method involves tricking the recipient into opening a document, visiting a website, or downloading a file via email, SMS, or chat services. The goal is to infect the device with malicious code and/or get over high permissions as the first step in a more comprehensive attack. Basically, phishing is a form of identity theft where the attacker pretends to be someone else, for example, an authority, employer or a company. The attack is then executed by the attacker sending false messages urging the recipient to click on links or download files in order to hijack sensitive information or infect the recipient's device with malicious code. Some common examples of phishing are: An attacker pretends ...

If you have ever handled a phone, you have probably heard of SIM cards, but what is a SIM card really? Simply put, it can be described as a small circuit board that acts as an intermediary between your mobile phone and your telephone company. It is the SIM card that enables your mobile phone to communicate with the mobile antennas provided by the telephone company where you have your subscription. SIM cards are also in iPads and tablets and fill the same function there. SIM stands for Subscriber Identification Module. In addition to enabling communication, the SIM card also contains the most basic parts of your user data. It contains information such as your telephone number and data that allows your telephone company to identify your subscription, which determines how much it co...
