Both AMOLED (Active-Matrix Organic Light Emitting Diode) and LCD (Liquid Crystal Display) are popular display technologies widely used in a variety of electronic devices like monitors, laptop screens, smartphone screens, TV screens, and more. The fundamental difference between AMOLED and LCD displays is in their screen illumination technology that is AMOLED display uses organic materials that emit light on the passage of electric current which illuminates the screen, while LCD display uses a backlighting system to illuminate the display screen. Another major difference between AMOLED and LCD displays is in their contrast ratios, i.e. AMOLED displays offer infinite contrast ... Read More

MOS stands for Metal Oxide Semiconductor. Metal Oxide Semiconductor is used for constructing transistors which are called MOSFET (Metal Oxide Semiconductor Field Effect Transistors). MOS transistors are being extensively used in a variety of modern electronic and power electronic devices like inverters, microprocessors, memory ICs, digital logic circuits, and more. What is a MOS Transistor? A MOS (Metal Oxide Semiconductor) transistor is a type of field effect transistor (FET) that can operate in both depletion mode and enhancement mode. A MOS transistor typically consists of three-terminals namely, Gate (G), Source (S), and Drain (D). The major parts of a MOS ... Read More

What is a Logic Gate? In digital circuits, a logic gate is a fundamental element of the digital circuit or system, that performs a specific logical operation. A logic gates typically has one or more inputs and only one output. The output of the logic gate is related to the inputs based on a certain logic. Some commonly used logic gates are: AND Gate, OR Gate, NOT Gate, NAND Gate, and NOR Gate. What is CMOS Technology? CMOS, Complementary Metal Oxide Semiconductor, is a predominant technology used for manufacturing integrated circuits (ICs). This technology is widely used for manufacturing a ... Read More

Both SMPS and UPS are types of power supplies used in various electronic devices like computers. Although, SMPS and UPS are completely different from each other in terms their primary function and many other parameters. The fundamental difference between SMPS and UPS is that SMPS (Switched Mode Power Supply) is designed to convert and regulate electricity for a specific application, while UPS (Uninterruptible Power Supply) is designed to provide backup power supply during mains power outages. In this article, we will discuss the important differences between SMPS and UPS. But before discussing the differences, let us first get a ... Read More

Digital signatures have gotten to be an integral portion/part of electronic communication and report administration frameworks, giving a secure and effective strategy for Signing and verifying digital documents and other shapes of communication. In any case, there are two diverse sorts of digital signatures: direct digital signatures and arbitrated digital signatures. Whereas both give a high level of security, they contrast in terms of their association with trusted third parties. In this article, we'll investigate the distinction between direct and arbitrated digital signatures and their applications in different businesses. Direct Signature A digital signature is a cryptographic method that permits ... Read More

What is a Computer? A computer is an electric device which is developed by Charles Babbage in 1822. It takes input data from the input devices, stores and process it, and produces output in the output devices. The processing is done by the Central Processing Unit. It is designed to perform various operations and tasks depending upon the instructions provided by a user. It can perform a wide range of tasks including word processing, graphic design, gaming, and internet browsing. Components of Computer Hardware Parts - Parts of a computer system which ... Read More

Optical fiber technology is defined as technology that is capable to transmit information in the form of light pulses with the help of a high-quality glass or plastic material. It looks like a transparent filament. In this article, we will go through optical fiber, its types, and the differences between them. So, let's begin with the definition of optical fiber. What is an Optical Fiber? Optical fiber is thin a thin or flexible glass or plastic material used to transmit information in the form of light. Glass or plastic serves as a medium to allow the passage of ... Read More

Introduction to Electricity Distribution Electricity distribution refers to the process of distributing the electrical power from generating stations to the consumers. In the first step, electricity is distributed to substations from the generating stations through transmission lines by increasing the voltage level to reduce transmission losses. In the second step, the increased level of voltage is stepped down using the transformers and supplied to consumers by the utility companies. In any industry, more than one voltage level is used for different purposes like 415 V, 690 V, 6.6 kV, and 11 kV. There is a process of voltage conversion ... Read More

In electrical power system, electrical earthing is one of the most important concept used to provide safety and protection to both human and equipment. Electrical earthing, also called as grounding, is basically a path of very low-resistance between the electrical equipment/system and the earth surface. The main purpose of electrical earthing in an electrical system is to provide a safe path for leakage electric current to flow into the earth’s conductive surface to reduce the risk of electrical accidents. Therefore, electrical earthing is an efficient and reliable way of protecting electrical equipment, individuals, and premises against electrical faults ... Read More

The automotive industry is undergoing a major revolution in the method we power our vehicle. The hybrid electric vehicle (HEV) and electric vehicle (EV) are at the leading position of this revolution. The fundamental difference between hybrid electric vehicle and electric vehicle is that electric vehicle relies only on electric batteries as energy source, while hybrid electric vehicle uses both fuel and electricity as the energy source. In this article, we will explore the other major differences between hybrid electric vehicle and electric vehicle. But before that let’s briefly get their overview individually. What is a ...
