Electronic commerce, also known as e-commerce, refers to purchases and sales carried out via the Internet (or other forms of remote data transmission). Early manifestations of e-commerce were found in the online portals of the 1980s, especially in the form of the Electronic Mall at Compuserve. Buyers and sellers conclude sales contracts online; often the business is largely automated. In a … [Read more...]
Basics on Insulator
Non-conductors are substances whose electrical conductivity is comparatively low and therefore usually not relevant and is below that of semiconductors. While the term is used in physics for arbitrary materials such as gases and vacuum, in technology it usually only means solids. Other partially synonymous terms are: Insulator: In addition to the material property described here, the term … [Read more...]
Resistance and Electrical Resistors: Part 2
This article is continuation of part 1 of this series. An important material parameter is the resistivity. The best-known resistor design is the cylindrical ceramic carrier with axial connecting wires. These connecting wires are routed through holes in circuit boards, for example, and soldered to the conductor track connections arranged there (through-hole mounting). A ceramic backing is coated … [Read more...]
What is Electric Current
Electric current, often just current, is a physical phenomenon in the field of electricity. In the everyday meaning of the term, it refers to the transport of electrical charge carriers, such as electrons in conductors or semiconductors or ions in electrolytes. This form of current is also known as a convection current. As described by Ampere's law, it is manifested by a magnetic field and usually … [Read more...]
The Future of Video Game Industry
Future prospects for the video game industry are promising. New monetization models are gaining ground as consumer demand increases and technology advances rapidly. The analysis conducted by Bain predicts that the global revenue for games will increase by more than fifty percent over the next five years. And gamers' presence in virtual realms, known collectively as the metaverse, is far superior … [Read more...]
What is Buffer in Computing
In computer science and telecommunications, buffers are storage devices for the intermediate storage of data. Depending on the task, the buffer can be structured differently. A buffer usually stores the data temporarily, and can be located in volatile or non-volatile memory. Piping and Queueing (FIFO Buffer) Buffers to compensate for differences in processing speed make it … [Read more...]
Modeling and Simulation
Modeling and simulation (M&S) refers to the use of models (e.g., physical, mathematical, or logical representation of a system, thing, phenomenon, or process) as the basis for simulations to generate data that can be used for management or engineering decision-making. Digital Application of Modelling and Simulation Modeling and Simulation's digital application uses … [Read more...]
Resistance and Electrical Resistors: Part I
Electrical resistance is a measure of the electrical voltage required to cause a certain electrical current to flow through an electrical conductor (component, circuit). Uniform quantities should be used or instantaneous values for variables that change over time. If the voltage is counted from a connection point A to a connection point B, the amperage in the conductor is counted positively as it … [Read more...]
What is Tourbillon (Watches)?
The tourbillon is a device in which the oscillation and escapement system of a mechanical watch rotates on its axis in order to achieve less positional accuracy, especially in wristwatches and pocket watches. Due to gravity, the accuracy of conventional watches is not the same in all positions. A tourbillon distributes the effect of gravity on the oscillating system evenly over all positions of at … [Read more...]
What is Binaural Sound Recording?
A binaural sound recording is a sound recording of sound signals with microphones that are intended to create a natural auditory impression with precise directional localization when played back only through headphones. When recording in artificial head stereophony, an artificial head is often used. In the past, the term binaural was often equated with stereo. In general, stereo sound … [Read more...]
Typical Characteristics of RISC Processors
Reduced Instruction Set Computer (RISC) is a design philosophy for computer processors. The design goal was to dispense with a complex instruction set that was convenient for assembly programming in favor of instructions that were easy to decode and quickly execute. This also allowed for higher clock speeds. The design philosophy opposite to RISC is called the Complex Instruction Set Computer … [Read more...]
