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 17 interesting Raspberry Pi projects to try out at home.
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.
Being able to access your home computer from another location is no longer a complicated matter thanks to remote connection. It is handy to be able to use your computer from the office and swap files. But IP addresses change often and this throws a spanner in the works. DynDNS (DDNS) services are the solution. In this article, we explain what these are and how you can access your computer via the...
The internet – just like other large networks – must be precisely subdivided. The network classes, used until the 1990s and not yet completely gone from the scene, were far too inflexible for the requirements of the digital world. CIDR can help: With classless inter-domain routing, it’s possible to create effective subnets and routes. We explain how this works.
Broadcasting is one of the most diverse means of communicating in a network. A data packet is sent to an entire network from one point, without having to specify one or more recipients. You direct your data packet to the broadcast address to do this. In this article, we explain what the broadcast IP is and how you can find out this address. We also give you a simple explanation of what a broadcast...
“Does it have Bluetooth?” This is a question you hear all the time in electronics stores, which is completely understandable, since this small, blue runic symbol has been a defining marker in our digital lives for quite some time, longer than most other wireless technologies. Even conventional kitchen appliances and motorcycle helmets all come with Bluetooth chips. You will find everything you...
Portable storage media such as CDs or USB sticks are still in demand when making backups or transferring files to another device. More and more often however, users also rely on cloud storage solutions that allow data to be outsourced to an external server environment. But what exactly is cloud storage? And how does this storage model offered by various providers work?
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 personalized 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 computing is an important aspect of digitization. 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...
