Today, every operating system has a graphical user interface, where we can navigate our computers using a mouse, stylus, or graphic tablet. But that wasn’t always the case. The first operating system used on personal computers, DOS, required users to enter commands into a command line using their keyboards. Keep reading to find out how a disk operating system works and what the best-known DOS are....What is a disk operating system (DOS)?
With the spread of Windows, DOS commands have become less important. Launching a program, copying a file, or creating a directory – this can be done using a mouse and the graphic interface. However, it’s still useful to know some basic DOS commands should you ever have any problems with the Windows display. Keep reading for an overview of the main commands.DOS commands
It is very important for a server service to always be available since this is directly related to an online company’s success. Many servers are susceptible to DoS and DDoS attacks, which cause overloads and trigger costly crashes. But which patterns do these attacks follow and which counter measures can be put into place in order to protect critical systems from being targeted?DDoS attacks
The Domain Name System, or DNS for short, plays an important role when surfing the web because it is used to translate domain names into server IP addresses. We explain what DNS is and show you exactly how the system works and which servers are used. We also explain the risks associated with DNS so that you’re well aware.Domain Name System (DNS)
Docker significantly simplified the use of software containers with its efforts at standardization. The lean container platform is part of a steadily increasing ecosystem that provides users a wide range of application options in the realm of software deployments, orchestration of containers, and multi-container applications, as well as continuous integration (CI) and continuous delivery (CD). In...The best Docker tools
Application virtualization with Docker containers is very popular. However, the subject may seem difficult to grasp at first because of all the concepts involved. The relationship between a Docker image and a Docker container often seems particularly confusing. In this article, we will explain what Docker containers are all about. We will go into detail about their structure, creation, and use.Docker container
Docker commands are used to control the Docker engine on a local host. When entered via the command line, they are translated into API calls to the Docker daemon. Docker commands can be used to manage images, containers, and volumes. If you tend to work with the software regularly, it is worth knowing a wide range of Docker commands.Docker commands
Without the Domain Name System, users of the World Wide Web would have serious problems when trying to load websites and other online presences. It’s only thanks to this system that internet addresses appear in their trusted text format: they’re actually nothing more than combinations of numbers. The communication between browser and name server responsible for this isn’t actually as secure as you...DNSSEC
Are you concerned about maintaining your privacy and use a VPN when surfing? Great – but this can make you uniquely vulnerable, too. We will show you the dangers posed by DNS leaks and explain how you can effectively protect yourself against them. In the process, we also look at DNS leak testers.DNS leak
