How exactly do you access the internet? Those who have a DSL contract, for example, first have to contact their internet provider’s node each time they connect. The provider checks the access authorization and establishes the connection to the internet. The so-called “Point-to-Point Protocol over Ethernet” (PPPoE) is used for this purpose. But how exactly does this protocol work?
We regularly encounter the file extension .exe when using our computers. Normally we always use these types of files if we would like to launch a program. But what are .exe files and how are they used? We show you how you can securely open .exe files on Windows and Mac operating systems.
What happens when all your data is suddenly lost? By regularly creating backups, you won’t have to worry about that. But many users underestimate the importance of this. At the same time, backups on Windows are straightforward. It’s also easy to create backups on Windows 7. You only need to change a few settings.
New computers using Windows 10 today usually boot with a special interface. The Unified Extensible Firmware Interface (UEFI) provides new functions and options for administrators and users. To better understand and get the most out of this advanced boot technology, you will need to become familiar with the basics of UEFI.
As in Windows, there is a shortcut that opens the Apple Task Manager. However, unlike the Windows version, the Mac Task Manager only lets you close programs. It doesn’t show you CPU load or energy usage. If you want to check these stats, you need to access the Mac Activity Monitor instead.
As a global computer network, the Internet provides the perfect foundation for gathering and distributing information. The World Wide Web, the most well-known Internet service, convincingly proves this fact. The older Usenet benefits from the Internet’s global network as well. In order to be able to transfer data, it relies on the unique NNTP, which is the focus of this article.
Using several programs at the same time has a noticeable impact on your computer’s performance. Many invisible processes run in the background that you may not know of. The Windows Task Manager provides an overview of all active applications and the option to end them. We show you the different options for opening the Task Manager.
The CAP theorem states that distributed systems can only guarantee two out of the following three points at the same time: consistency, availability, and partition tolerance. In this article, we will explain where the CAP theorem originated and how it is defined. We will then provide some concrete examples which prove the validity of Brewer’s theorem, as it is also called.
In Windows, you can adapt frequently required shutdown routines to your individual needs in many different ways. For this, Windows provides an appropriate tool in the command line, which is also referred to as the prompt – CMD or cmd.exe. We introduce shutdowns via CMD, which can handle efficient, simple, but also more complex shutdown routines.
Various network features like data sharing are regulated by the SMB protocol in Windows. For maximum compatibility, Windows 10 still supports communication via the first version of this protocol – known as SMBv1, SMB 1.0 or CIFS. Since using this protocol is inadvisable for security reasons, this article explains how to disable SMB1 in Windows 10.

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.
