  • Know-how

Those working with network technology are bound to encounter the ISO-OSI model sooner or later. This system subdivides communication between computer systems into seven different layers. Each of these layers is assigned a certain task. With the help of this layer model, subareas of abstract processes are able to be descriptively explained.

RARP (Reverse Address Resolution Protocol)

RARP (Reverse Address Resolution Protocol)

  • Know-how

Out-dated technology can still be interesting. Even though the Reverse Address Resolution Protocol was introduced in 1984, and considered obsolete the following year due to the Bootstrap Protocol, it continued to be used long after. The RARP has not completely disappeared from network technology even today. As the Reverse ARP, this protocol is a counterpart to the Address Resolution Protocol. But…

Network News Transfer Protocol (NNTP)

Network News Transfer Protocol (NNTP)

  • Know-how

As a global computer network, the Internet provides the perfect foundation for gathering and distributing information. The World Wide Web, the most well-known Internet service, convincingly proves this fact. The older Usenet benefits from the Internet’s global network as well. In order to be able to transfer data, it relies on the unique NNTP, which is the focus of this article.

MultiProtocol Label Switching (MPLS)

MultiProtocol Label Switching (MPLS)

  • Know-how

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).

TCP/IP

TCP/IP

  • Know-how

Without TCP/IP protocols, you wouldn’t be able to read the words on this page. TCP and IP, the two foundational protocols of the suite, along with other related sets of rules, define how computers communicate over the Internet and other networks. In fact, the standards are so established that every device on the Internet follows these protocols to ensure the smooth transfer of data.
