Those working with network technology are bound to encounter the ISO-OSI model sooner or later. This system subdivides communication between computer systems into seven different layers. Each of these layers is assigned a certain task. With the help of this layer model, subareas of abstract processes are able to be descriptively explained.
Whether you’re on a desktop PC, smartphone or tablet – without an operating system it would simply be impossible to use your device. It’s for this reason that the system software and the respective installation files are loaded immediately when the working memory is first supplied with power. This is made possible by bootloaders, which are activated directly by the firmware specific to the...
Windows shortcuts can help you save a lot of time when working on a computer. With a simple hand gesture, you can use shortcuts to perform recurring tasks. In this article, you will find a practical overview of the most important Windows keyboard shortcuts which will make your everyday life easier and working with Windows more convenient.
The Domain Name System (DNS) is important for day-to-day web browsing. However, it is increasingly obvious that the conventional DNS has some weaknesses. New providers are attempting to fill in the gaps. One of them is Quad9. Given that it has no commercial interests – and that it provides a high level of security and privacy – the public DNS resolver is a genuine alternative to the more widely...
Due to increasing globalization, processes for connecting and networking digital infrastructures are becoming increasingly important. The remote procedure call (RPC) plays a key role in this context, as it enables efficient inter-process communication designed for task distribution in networked client-server architectures.
For USB sticks to work as storage media, they need to have their own file system. Without this, it can be added manually by formatting the flash drive. Mac users have a tool available for this with the “Disk Utility” program. Read this tutorial article to find out what the individual steps are and which file systems are available to use.
Try and imagine a world where you don’t have to memorize passwords: Thanks to FIDO2, this could soon become a reality. Authentication in online stores or for online banking can be done through a fingerprint or hardware token. The latter can communicate with laptops of PCs through a USB, NFC or Bluetooth. To enable conversations between two devices, FIDO2 uses the Client to Authenticator Protocol...
The risk for businesses to fall victim to a zero-day exploit has increased in recent years. More and more often, cybercriminals can take advantage of as-yet undiscovered weak points in business software in order to steal or manipulate data. It is difficult to protect against these attacks, but businesses can take some measures to improve their security.
In order to provide the best support for the rapid progress in hardware development, system software is also constantly being improved. Along with comfort, performance and security are crucial factors. One good example is the GUID Partition Table (GPT) partition style, which has already replaced the classic master boot record in many system architectures. We’ll show you why.
Partitions help you to manage disk space more efficiently. For example, by splitting up the available disk space into smaller sections, you can easily separate system files from application files and personal data. However, if you want to create a partition, you will have to decide whether to use MBR or GPT. So how does each of these partitioning styles work? And what’s the difference between...
IONOS Server Guide: professional tips on configuration and administration
Servers are what make up the physical basis of the internet. Setting up your own professional site, putting products online for sale, or connecting multiple company locations with one another: all of these tasks require the support of high-performance computers. And it doesn’t matter if you purchase hardware resources for your own data center or opt for the flexibility of cloud services: operating a server comes with the challenge of independently configuring and administering hardware components. But don’t worry, there’s a lot of support out there for these tasks. In the Server Guide of IONOS’s Digital Guide series, you’ll find regular articles, news, and tutorials on how to operate this indispensable component of today’s IT infrastructure.
Server information for businesses, developers, and tech hobbyists
Packed with practical tips, our guide covers a wide spectrum of topics primarily aimed at mid-sized companies, freelance developers, and tech hobbyists. While some articles, like ‘What is a server?’ or ‘DNS – name resolution online’ cater more to beginners, experts are by no means left hanging; there’s a wide range of detailed texts and tutorials on important tasks like choosing the best operating system, filling security gaps, or getting the best possible performance out of your software and hardware.
What you can expect in the IONOS Server Guide
If you take a look, you’ll notice our guide is divided into four different subcategories, each covering a different topic. The ‘KnowHow’ area sets out to familiarize beginners with the basics of operating a server. Details on different server types and how to use them are also laid out here. Tips and tricks on managing server software is found under the keyword, ‘Configuration’. The category, ‘Security’ is all about dealing with potential problems server operators may encounter from online threats. Conventional methods of attack, like viruses, worms, and Trojans, and what you can do to combat them are explained here. And the category, ‘Tools’, provides useful guidance on what resources can help make administering your server a more manageable task.
