File Transfer Protocol

FTP: File Transfer Protocol explained

The Internet is dependent on various protocols for facilitating communication. The File Transfer Protocol ensures that we can upload data to a server and download it again at a later point. You’re bound to run into FTP again and again, especially in the context of creating websites.

An introduction to gRPC

gRPC – Paving the way to the client-server communication of the future

Remote procedure calls have long played a critical role in inter-machine communication when it comes to client-server architectures. For several years now, gRPC has proven to be a worthy successor. This framework uses powerful strategies to fulfill the increased demands of global networking and end-to-end digitisation.


DNS over HTTPS: more security on the net

The Domain Name System (DNS) is considered “the phone book of the Internet”. You can use it to find the right IP address for each URL. However, the system traditionally works without any encryption. Virtually anyone can listen in when you send a request. Not only is this slightly worrying, but it can also be dangerous. DNS over HTTPS tries to close the decade-old security gap.

TCP ports and UDP ports

UDP and TCP ports: A list of the most important ports

Protocols control communication on the Internet. Doors have to be opened so that packages of data can get into systems and come out of them. These ports are an important aspect of the Internet. There are over 65,000 possible UDP and TCP ports, which are broken down into well-known ports, registered ports, and dynamic ports. Which ports are important?

What is Kubernetes?

A comparison of different servers

Servers by comparison in web hosting

Carry out a server comparison and you will notice that website operators have a large selection to choose from. Professional hosts offer virtual, dedicated, and cloud based servers in different performance levels. How do these server models differ from one another? What features does a root server have in comparison to a managed server? Which type of hosting is best for your web project? Take a...

Network protocol: Standards for data exchange

Network protocol: The basis of electronic data exchange

For computer systems to be able to communicate with each other and exchange information, they need common ground, just like humans must share a common language. But computers don’t rely on foreign language lessons, and instead only need the appropriate network protocol to successfully communicate. This provides guidelines and structures for the data transfer, and so plays a decisive role in the...

UDP - User Datagram Protocol

UDP: What is the User Datagram Protocol?

The Internet protocol family – the cornerstone for communication on the Internet – has around 500 members who work on a wide variety of layers. For example, the connectionless User Datagram Protocol (UDP) is responsible on the transport layer for the transmission of packets that were previously addressed via the Internet Protocol (IP). In this guide, you can find out exactly what distinguishes...
