So that data can get from one place to another, it not only needs to know the right address, it also needs to know the best way to get there. The network layer is responsible for both of these things. It equips packets with addresses and takes care of the routing. In this article, you’ll find out what the network layer is, what functions it carries out and what network layer protocols there are.
The data link layer works closely with the first and third layers, ensuring that data gets from the sender to the receiver without any delays or errors. In the event of an error, the layer will step in and try to redirect it or send it again. In this article, we’ll explain the functions of the OSI data link layer in detail.
In the OSI model, the physical layer puts tools in place to activate and deactivate physical connections. These tools also make it possible to monitor connections while data is being transferred. In this guide, we’ll explain the features and services in the OSI physical layer, what its exact role in the OSI model is and which technologies are used for the physical layer.
If you still prefer to use one of the many Linux distributions with command lines, you can use a terminal multiplexer such as tmux. Functionally, tmux resembles GNU Screen, offering multitasking in the form of many parallel console sessions in one terminal and user-defined configurations. Our tutorial will explain how tmux works.
Which storage method is the best solution for you or your company? You have several options to choose from. Object storage is relatively new, but already very popular. Data is turned into objects. Instead of using folders, everything is on the same level. How does object-based storage work? And what are the advantages?
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.
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...
Growing sums of data require cost-effective, high-performance storage solutions. One option for fulfilling this requirement is a network attached storage. In business contexts, this model has already established itself as a viable alternative to file servers, hard drives, and the cloud. Private users have also caught on and use NAS systems at home. But what is a NAS? Read on, and we’ll show you...
When talking about web hosting, it is impossible to avoid the term ‘server’. So what is a server? And how does it work? In IT, there are actually two definitions of the term. The traditional server is the software for network services, but more recently the word has also been used to describe the corresponding hardware used to carry out server programs. Here is our overview of the most common...
Jitter may be the reason for a video chat faltering, a screen flickering or a video buffering. So, what is jitter exactly? It is a delay or deviation in the transmission of data packets. In our article, we’ll look into why jitter happens, the different types, how it is measured and what you can do to reduce or even prevent it.
