The container platform Docker offers native functions for the orchestration of containers in physical or virtual clusters. Docker also offers a tool for the deployment of multi-container apps with Compose. Thanks to the native swarm mode, you can scale complex applications by yourself on any number of Docker hosts. We show you how that works and offer comprehensive help in our tutorial for Docker [...]
Every day we work with text on PCs, smartphones, tablets and other computer equipment using our keyboards. We expect letters, numbers, and characters to appear on the monitor before us. The fact is that there is a decades-old coding system behind this everyday function. Since the 1960s, ASCII has determined how computers interpret our input. We have prepared a practical ASCII table to help you [...]
‘DNS server not responding’ is a typical error response on Windows. Its presence indicates that some sort of problem is occurring with your internet connection. This phenomenon can be the result of many different causes. In addition to network problems, routers, Windows Firewall, and the web browser are also taken into account when troubleshooting.
In the days of mainframe computers and the first smaller networks, terminals were a crucial building block for sharing hardware and software resources. It is no coincidence that terminal servers – the central administrative entity of such networks – are in demand decades later, now that applications are to be made available to multiple users.
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 duel between Linux and Windows may have an obvious victor on the home computer front, but the battle for server use paints a very different picture: since the beginning, Linux has bested Windows, as usage figures show. But many users remain unconvinced by statistics and rightfully ask the question: what are the actual differences between the two platforms?
Apache vs. NGINX – while one is said to be bulky and unwieldy, the other is considered slim and high-performance. But can we be this general? In fact, both web servers are based on fundamentally different concepts when it comes to connection management, interpretation of client requests, or configuration options. The range of functions also display clear differences in software alignment. While [...]
When computer information is sent in TCP/IP networks, it is first decompressed into individual data frames. In this way, you can transfer data of nearly unlimited size. The frames also contain the target system’s MAC address, without which a transmission would not be possible. If the physical address is not known, the sender must first be determined using the ARP Address Resolution Protocol. Here, [...]
Thanks to its minimalist dimensions, the Raspberry Pi Zero is the ideal component for all craft projects looking to utilize 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 [...]
The single-board computer Raspberry Pi has enjoyed high popularity since its release in 2012. With the increasing number of possible applications, the minicomputer has become an interesting and practical solution for various branches of industry. As a result, more and more operating systems for the British computer are being introduced to the market. Choosing the appropriate Raspberry Pi [...]
