DHCP: An overview of the Client/Server protocol

DHCP: What’s behind the Dynamic Host Configuration Protocol

If you’re connected to an internet router and power on your computer, it automatically obtains the necessary network parameters, such as the IP address, subnet mask, or DNS server. This is made possible by the Dynamic Host Configuration Protocol (DHCP), which simplifies address assignment when connecting to the internet and makes setting up local networks easy as pie.

SNMP: Simple Network Management Protocol

SNMP (Simple Network Management Protocol): the protocol for network management

The communication protocol SNMP (Simple Network Management Protocol) is an elementary component of many network management applications. It defines a number of message types that greatly simplify the monitoring and administration of individual network participants such as PCs, routers, servers, switches, firewalls, or printers. How exactly the SNMP protocol works and what fundamental adjustments...

MPLS:  What is Multiprotocol label switching?

MPLS: What’s behind the network technology

Speed and reliability play an important role for data transfer in networks. They reflect the quality of the connection, which is why providers do everything they can to guarantee the agreed services. A method primarily used in virtual private networks is the so-called multiprotocol label switching (MPLS).

SNTP: simple network time protocol

Simple network time protocol: the stripped-back protocol for time synchronization

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. Synchronisation methods that keep the clocks of the individual network participants in sync are utterly indispensable. One of the simplest methods to achieve time...

Protection against ransomware, spyware, and scareware

Ransomware, adware, etc. – how can you protect yourself?

The internet is a playground for cybercriminals and fraudsters – for many, this is an annoying and frightening reality. The threats from unwanted software range from harmless advertising to trojans, which can paralyse complete computer networks. The forms of malicious software or malware are diverse, the countermeasures often very simple. In our article, you can read about how ransomware, spyware,...

Err_Connection_Timed_Out

Correcting the error “Err_Connection_Timed_Out”

The error message “Err_Connection_Timed_Out” appears frequently on Google Chrome and means that an error has occurred when trying to access a webpage. This is usually caused by the target server taking too long to send a reply, which results in the browser terminating the communication attempt. Find out in our guide what “Err_Connection_Timed_Out” means, what measures you can take to correct the...

Remote access for network storage

Remote access to the network storage

Are you using a NAS system as a home server and want to connect it to the internet? It’s simple to do. We explain how to assign a fixed LAN IP address to your network storage and open the corresponding ports for the desired service in the router firewall. You will also learn how to make your NAS system permanently available under a consistent address despite daily disconnections carried out by the...

What is Internet protocol? – IP definition, etc.

What is Internet Protocol (IP)?

When networking a computer system, protocols play an important role. An example is the Internet protocol, which was published in a first specification in 1981, and is the indispensable basis for the smooth sending and receiving of data packets. But what is behind the RFC standard? And how does the Internet protocol actually work?

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...

Arpanet | Definition & history of the internet predecessor

ARPANET: The internet in its infancy

Before the internet, there was Arpanet. In the beginning, the network was only four computers, yet, it was extremely important for the development of the digital world. During the Cold War, several American scientists and technicians created the cornerstones of a global network. Learn more about the interesting history of Arpanet and the network’s technical achievements.
