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.

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

Microsoft Photo Software makes it tricky to resize images. However, they provide another program that greatly simplifies. If you resize an image, the file size may be smaller, which makes the image easier to send, for example. However, you will lose information in the image during reduction, which cannot be recovered. Windows 10 has a pretty decent photo and image editing app in the form of Photos, but the program places more emphasis on features than on usability. You may have discovered that its user interface is not intuitive to use and that most of the features are well hidden. In addition, the program wants to take away control of your images. To quickly resize an image, Powertoys, Microsoft's experimental software, is a better, more convenient alternative. You install it on ...
