What is filesharing?
Filesharing
  • Know-how

Filesharing is when you share documents, music, videos, images, etc. on computer networks or obtain such content from other users. But what exactly is file sharing? And what are the different ways of sharing files with other people on the Internet and other networks? Everything you need to know about file sharing can be found here.

What is Docker?
Docker (The container technology)
  • Know-how

The Docker virtualization solution has transformed application development. In some cases, standardized containers are used to create gigantic clusters of loosely coupled microservices. They run as distributed swarms across system and infrastructure boundaries. Special tools and workflows are used to deal with the resulting complexity.

What is DBaaS
DBaaS (Database as a Service)
  • Know-how

Relational database systems such as MySQL no longer necessarily have to be hosted in-house. With Database as a Service – or DBaaS for short – one or more databases are outsourced to the cloud, saving costs and capacity. Here we explain how DBaaS works, what it’s suitable for, and what advantages and disadvantages it has.

What is Cloud Storage?
Cloud Storage
  • Know-how

Portable storage media such as CDs or USB sticks are still in demand when making backups or transferring files to another device. More and more often however, users also rely on cloud storage solutions that allow data to be outsourced to an external server environment. But what exactly is cloud storage? And how does this storage model offered by various providers work?

WAN
WAN (Wide Area Network)
  • Know-how

Anyone who deals with networks will come across the term WAN (Wide Area Network) sooner or later. Lots of people confuse WAN with WLAN or LAN. But a Wide Area Network clearly differs from these two other network types. We explain what a WAN is used for, how it’s structured, and compare it with related networks.

URL: What is a Uniform Resource Locator?
What is a URL (Uniform Resource Locator)?
  • Know-how

The Uniform Resource Locator (short: URL) is one of the basic standard tools of the internet. URLs make it easy to uniquely identify resources on the internet and find their location. Internet users use webpage URLs to surf the web, follow hyperlinks or download files. The concept is based on a human tangible syntax that is automatically read out and interpreted by machines.

Unix vs. Linux
Unix vs. Linux
  • Know-how

Our in-depth comparison of Linux vs. Unix explores the close relationship between the two operating systems, the history of their development and their key differences. We provide a comparison of their advantages and disadvantages highlighting the strengths and weaknesses of the two systems which have established themselves as viable alternatives to Windows systems on the server market.

Unicast
Unicast
  • Know-how

Do you want your data to reach just one recipient? Then send a unicast. Whether it is IPv4 or IPv6, unicasts find the right target. Accessing websites, sending e-mails, file transfers all use this form of addressing. But what is technically behind it, and how do unicast and multicast differ?

Token ring
Token ring – IEEE 802.5
  • Know-how

A glance back into history can reveal a lot. Although token ring networks, or ring topologies, are nowhere to be found nowadays, token rings remain an interesting form of technology. Why the model, which is actually quite good, was outdone by its competitor Ethernet is due to the merciless nature of the tech market. Read the history behind token rings, along with a definition of the system that...

SNTP: simple network time protocol
Software Defined Data Center (SDDC)
  • Know-how

An exact system time on a computer is especially important when devices need to exchange data. Cross-system processes quickly come to a standstill if the generated time stamps are very different from the time that applies to the system. Synchronization methods that keep the clocks of the individual network participants in sync are utterly indispensable. One of the simplest methods to achieve time...
