What is OWASP?OWASP (Open Web Application Security Project) is a non-profit organization dedicated to enhancing software security. OWASP is based on an "open community" approach, allowing anybody to engage in and contribute to projects, events, online conversations, and other activities. OWASP's guiding concept is that all resources and information on its website are free and easily accessible to anyone.OWASP offers a variety of tools, forums, projects, and events, among other things. In a nutshell, OWASP is a one-stop-shop for everything web application security, supported by the collective wisdom and experience of its open community contributors.What are the OWASP Top 10 ...

Credit Card Cracking: What is It?Card cracking is a credit card fraud that makes use of bots (software that runs automated tasks over the Internet). Cracking is founded on the notion that obtaining a credit card number, also known as a Private Account Number (PAN), and the name inscribed on the card is simple. Bots are used by attackers to guess and validate the additional information needed to "break" and use a credit card fraudulently.Criminals can get PANs in a variety of ways −Purchasing PAN listings on the dark webThrough associates who work in retail or restaurants and have access ...

A transistor (or bipolar junction transistor) is a three-terminal, three-layer and two-junction semiconductor device, used as the digital switch and amplifier in the electronic circuits.A transistor consists of three layers of P-type and N-type semiconductor materials and the name of these layers are emitter, base and collector. The three terminals are taken out from these three layers.Based on the arrangement of the semiconductor layers, the transistors are of two types as −NPN TransistorPNP TransistorRead through this article to find out more about NPN transistor (BJT) and PNP transistor and the key differences between them.What is NPN Transistor?An NPN transistor is ...

The directed flow of electrons or charge in an electric circuit is known as electric current. Based on the nature of flow of electrons (or electric current), the electric current is classified into two types: AC (Alternating Current) and DC (Direct Current). Go through this article to find out more about AC and DC and how they are different from each other.What is Alternating Current?AC stands for Alternating Current. The type of electric current whose magnitude changes continuously and direction changes periodically is known as alternating current or AC. In practice, the alternating current is produced by alternating voltage source ... Read More
Multimeters and voltage testers are both testing and measuring devices that are used to measure a wide range of electrical quantities. Go through this article to get a basic understanding of how multimeters and voltage testers work and how exactly they are different from each other.What is a Multimeter?A multimeter is a standard measuring instrument that is used for measuring multiple electrical quantities in an electric circuit. With a typical multimeter, one can measure AC voltage and current, DC voltage and current, resistance, continuity, and other values.Basically, a multimeter is a combination of a DC voltmeter, AC voltmeter, DC ammeter, ...

Both diodes and transistors are types of semiconductor devices that find a wide range of applications in different electronic circuits such as clippers, clampers, oscillators, rectifiers and amplifiers, etc. Go through this article to get an overview of how diodes and transistors function and how they are different from each other.What is a Diode?A diode is a semiconductor switching device which is constructed by combining two layers of N-type and P-type semiconductor materials. For this reason, a diode is also called as PN junction diode. The circuit symbol of the diode is shown in Figure-1.A diode has only one PN-junction ... Read More
A transformer is a static electric machine which changes the level of voltage and current in the circuit without changing the power and supply frequency. The electrical transformer works on the principle of mutual inductance.Based upon the number of windings used in the transformer, they can be grouped into two different categories −Two-winding transformer (or typical transformer or conventional transformer)AutotransformerRead through this article is to find out the major differences between two-winding transformer and autotransformer.What is a Two-Winding Transformer?A two-winding transformer or conventional transformer is one which consists of two magnetically coupled windings (primary and secondary) which are electrically insulated ...
