Are you a Windows user, but aren’t sure what version of the operating system you have installed on your PC? This article introduces three ways of checking your Windows version in just a few seconds: using a keyboard shortcut, via the Control Panel, or using the Windows Command Prompt (CMD).

The different network types

Network types at a glance

When several computers are connected to one another it is known as a network. Networks enable data exchange between different devices, making shared resources available. Different network types are implemented depending on which transmission techniques and standards are used. These differ in terms of the number of connected systems and potential reach.

Setting up a Minecraft server with a dedicated server

Setting up your own Minecraft server

Many players of the popular game, Minecraft, need or want to use their own servers. Hosting your own Minecraft world is the only way users are able to adjust the general settings of the online multiplayer mode. Setting up a personal Minecraft server isn’t as daunting as it sounds, however. Find out just exactly how it works and what type of server is best suited for hosting Minecraft.

MAC address

MAC address (media access control)

Without a MAC address, nothing in a network will work on your device. Just as your postman needs a valid address to reliably deliver the mail, the transmission of data packets in computer networks is only possible with the unique hardware address of the target device. When it comes to a MAC address, at least there is one address available on each network-compatible device. But what is the MAC...

CSMA/CD - Carrier Sense Multiple Access / Collision Detection

CSMA/CD: Explanation of the process

Rules must be observed when communicating in a group. This is no different with local networks: CSMA/CD regulates how data packet collisions must be handled in a LAN network. But what happens if several participants attempt to simultaneously carry out a transmission and the information gets lost? Carrier Sense Multiple Access with Collision Detection is an important procedure for smooth network...

CSMA/CA - Carrier Sense Multiple Access with Collision Avoidance

CSMA/CA: definition and explanation of the method

How do you achieve order in a wireless network? If all devices were to send information amongst themselves in an uncoordinated way, the data would rarely reach the recipient without problems. With CSMA/CA, there is a protocol that organises the process and avoids collisions – without the need for central coordination. It’s a complex time management system. We go through the process step by step so...

What is Object Storage?

Object storage: The modern storage solution

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?

What is ICMP protocol and how does it work?

What is the ICMP?

In the background, numerous protocols ensure that communication and data transmission work in computer networks. As the most prominent representative, the Internet Protocol plays a fundamental role. Without its’ various extensions and additions they would be nowhere near as versatile, as is the case in the current protocol. Thanks to the possibilities offered by ICMP protocol error messages and...
