On Monday 08.03.2021 we, the trainees and students in the first year of apprenticeship, had a training about the basics of networks and network management. As the day progresses, we got to know different devices such as router, switches and access points. Also the different types of networks and what you should keep in mind, when configuring your own network, was part of the day.
During the training, we got several interesting facts about how the network in our company is built and how the different locations are linked to each other. This helped to understand the connection between the theoretical content and the practical usage. Beside this topic, we also learned some facts, which are nice to know, when setting up and managing a private network.
For example, that all computers in a network are connected either by LAN (Local Area Network) or WLAN (Wireless Local Area Network). Therefore every PC gets assigned an IP address, which is at least in its network unique. When looking on IPs, there are two different standards used nowadays: The older format is IPv4 (255.255.255.255, four numbers, each from 0–255), the newer one is IPv6 (wrote in hexadecimal, e.g.: 2001:0db8:85a3:08d3:1319:8a2e:0370:7344), which was introduced to have more combinations available to connect all web enabled devices to the internet.
Every now and then we got some questions to which we had to research for the correct answers. To proof our new skills, we got challenged to find and fix some errors in a simple network at the end of the day.
