The Internet protocol family – the cornerstone for communication on the Internet – has around 500 members who work on a wide variety of layers. For example, the connectionless User Datagram Protocol (UDP) is responsible on the transport layer for the transmission of packets that were previously addressed via the Internet Protocol (IP). In this guide, you can find out exactly what distinguishes...
Cloud computing is an important aspect of digitisation. An offshoot of this technology is the public cloud, which provides storage space and IT services publicly on the internet. Data protectors see certain dangerous weaknesses in this concept, but public access offers enormous potential, and data protection concerns are increasingly stimulating innovative solutions. We explain what lies behind...
Should data and processes be handled in a private or public cloud? If a company wants to use cloud computing, they first need to choose one of the many providers available. Using the personalised services offered by a private cloud, companies can address a wide range of business related and operational challenges. Separating operations also makes a private cloud more secure than a public cloud.
Cloud services are becoming increasingly important for companies. In addition to software and infrastructure that can be booked via the provider's cloud (SaaS and IaaS), cloud-based platforms for developing new applications (PaaS) are also becoming more popular. Companies can make their self-developed software available on these platforms without having to set up the necessary infrastructure...
Thanks to its minimalist dimensions, the Raspberry Pi Zero is the ideal component for all craft projects looking to utilise every last inch of space. Having arrived on the market in 2015, the minicomputer has been used in numerous constructions across a range of functions. A brief introduction to the minicomputer and of the most interesting Raspberry Pi Zero applications and ideas can be found in...
Raspberry Pi is an inexpensive small form factor PC that can behave like a standard computer in many respects. Users can use this innovative mini-computer for all kinds of functions, from setting up an operating system to surfing the web, to using it as a server or a media center, and much more besides. Discover 10 interesting Raspberry Pi projects to try out at home.
The PostgreSQL database management system, also known to many as Postgres, has many decades of development behind it. It originally started as a project at Berkeley University in California. Today, the open source database continues to defy solutions from commercial competitors, since the development team is constantly working on its functionality and performance. But what exactly is PostgreSQL?...
Cloud computing is not just an IT industry buzzword, it’s a model that many companies already employ effectively and profitably into their organisations. A large portion of IT infrastructure is no longer managed on-site. Instead, the required services can be rented via a service on the internet. Here we provide a cloud computing definition and explain exactly how it works.
A glance back into history can reveal a lot. Although token ring networks, or ring topologies, are nowhere to be found nowadays, token rings remain an interesting form of technology. Why the model, which is actually quite good, was outdone by its competitor Ethernet is due to the merciless nature of the tech market. Read the history behind token rings, along with a definition of the system that...
Autonomous cars, intelligent factories and self-regulating supply networks – a dream world for large-scale data-driven projects that will make our lives easier. However, what the cloud model is and how it works is not enough to make these dreams a reality. The challenge of effectively capturing, evaluating and storing mass data requires new data processing concepts. With edge computing, IT...
