User-generated content (UGC) refers to media content that is not created by the provider of a media channel, but by its users. Originally, the term comes from web publishing and new media content production circles. In the 1970s and 1980s, all content and information was checked by gatekeepers such as newspaper editors and publishers before it was published. Today, thanks to new technologies, … [Read more...]

What is Massively Multiplayer Online Role-Playing Game (MMORPG)
A massively multiplayer online role-playing game is a computer game that combines role-playing and online multiplayer components. Players take on the role of a character in an often fantastical or sci-fi-like world and control their actions. The distinguishing feature of MMORPG from single-player or small multiplayer online role-playing games lies in the number of interacting players and the … [Read more...]
What We Mean by the Phrase Virtual World
A virtual world is the representation and simultaneous perception of the totality of a world of objects of apparent objectivity in three-dimensional space in a computer-generated, interactive virtual environment in real time. They are not synonymous with virtual reality and augmented reality, although the technologies can be used. The user accesses a computer-simulated world consisting of … [Read more...]
How Door Access Control System Works
Access control controls access via a set of rules defined by the operator "Who – When – Where" so that only authorised persons have access to the areas in buildings or protected areas on a site that have been approved for them. Access authorisations can be limited in time (expiry period, time). Access authorisation can be checked by people, e.g. employees of a security service, or by technical … [Read more...]
What is Inductive Coupling
Inductive coupling is the mutual magnetic influence of two or more spatially adjacent electrical circuits by electromagnetic induction as a result of a change in the magnetic flux. Counter-induction is the basis of some technical devices (such as the transformer), but it can also be a very undesirable effect (such as in the field of electromagnetic compatibility). One parameter that describes this … [Read more...]
What is a Log File
A log file contains the automatically maintained log of all or certain actions of processes on a computer system. Important applications can be found above all in process control and automation. In principle, all actions that are or could be necessary for a later investigation (audit) are recorded. The flight recorder in airplanes is an example of continuous logging, but it is rarely evaluated, … [Read more...]
Docker Kubernetes Book
Docker and Kubernetes have assumed great importance in modern software development. To put it in plain terms, Docker simplifies the process of packaging and distributing applications. It utilizes containerization, encapsulating apps, and dependencies. As an orchestration platform, Kubernetes manages containerized applications and automates deployment, scaling, and operations. Docker and Kubernetes … [Read more...]
Types of Wireless Power Transfer
In our earlier articles, we have discussed about Basics of Wireless Power Transfer and Pros and Cons of Qi Charging. Wireless power transfer is the process of transferring electrical energy from one object to another without contact. The most widely used method is inductive energy transfer. At close range of a few centimeters, it has a comparatively high efficiency of about 90%. Examples of … [Read more...]
Basics of Wireless Power Transfer
Wireless power transfer, also known as contactless power transfer, wireless power transfer, or contactless power transfer, is the process of transferring electrical energy from one object to another without contact. The main feature is that the electrical energy required for operation is not supplied along electrical wires and by means of electrical contacts, but through non-wired electromagnetic … [Read more...]
Pros and Cons of Qi Charging (Inductive Energy Transfer)
Qi is a proprietary standard of the Wireless Power Consortium (WPC) for wireless energy transmission using electromagnetic induction over short distances. According to WPC, the Qi standard, which was founded in 2008, is supported by over 1000 different devices and counts over 200 companies among its members. The first supplier of smartphones was the South Korean manufacturer Samsung, whose Samsung … [Read more...]
Pros and Cons of Internet Access via Satellite
Internet via satellite is a satellite-based Internet access. Geostationary satellites are often used for this purpose, but satellite constellations in low or medium Earth orbits (LEO or MEO) are also used. Basically, a distinction must be made between two types of satellite connection. In 2-way satellite connection the outward and return channels (downstream and upstream) are established via a … [Read more...]
