Abstract:
The online platforms have been in a continuous development since the beginning of their appearance, being classified according to the field of activity. This article discusses some features of the online educational platforms, that serve the distance learning adopted during this pandemic period by the majority of nations on the planet, to continue the educational progress, at all levels of learning. The article is intended exclusively for the platforms used at the pre-university level of education and illustrates theoretical notions about them, represented by typologies, characteristics, and t

Online shopping is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser. Online shopping has grown in popularity over the years, mainly because people find it convenient and easy to bargain shop from the comfort of their home or office. One of the most enticing factor about online shopping, particularly during a holiday season, is it alternates the need to wait in long lines or search from store to store for a particular item.

Many optimisation problems are of an online—also called dynamic—nature, where new information is expected to arrive and the problem must be resolved in an ongoing fashion to (a) improve or revise previous decisions and (b) take new ones. Typically, building an online decision-making system requires substantial ad-hoc coding to ensure the offline version of the optimisation problem is continually adjusted and resolved.
