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...]
Basics of App Store
App Store is the name given to an Internet-based digital distribution platform for application software. The software comes either from the operator of the platform itself, but mostly from third-party providers, such as free software developers and software companies. The service allows users to select and download software from a catalog for mobile devices, such as smartphones and tablets, and … [Read more...]
Pros and Cons of Web Application
Traditionally, a web application is increasingly run on the server side. There are also approaches as distribution variants that provide for a more client-heavy execution of a web application. The web client is becoming an increasingly independent entity to free up server-side resources. These approaches are particularly relevant for B2C applications – such as Facebook or Gmail – as such projects … [Read more...]
How Web Application Works
A web application is an application program based on the client-server model. Unlike traditional desktop applications, web applications are not installed locally on the user's computer. Some of the data processing takes place on a remote web server. The results of the data processing are transmitted to the user's local client computer (thin client). A web application is usually used via a web … [Read more...]
Pros and Cons of Online Outsourcing

Examples include programming and web design assignments, multimedia productions, logo creation and search engine optimization. However, business services … [Read more...]
Testing Levels of Software Testing
A software test tests and evaluates software for its fulfilment of the requirements defined for its use and measures its quality. The knowledge gained is used to detect and fix software errors. Tests during software development are used to ensure that the software is put into operation as error-free as possible. The classification of the test stages (sometimes also called test cycles) follows … [Read more...]
