No, they're not inherently difficult. Difficulty depends on your experience and the specific tasks involved.

I’m exploring computer science at school. In Poland, lessons focus mainly on theory rather than hands-on practice. I see explanations on paper, descriptions of processors, screen presentations instead of direct interaction, demonstrations of inserting components into sockets, or examples of video programs that demand more processor power. Some guides explain how to check processor performance using tools like CPU Z or Aida64, and discuss temperature monitoring. From the network side, we began with a discussion about routers, cables such as optical fibers, IPv4 addressing, broadcast addresses, netmasks, and host counts. It reminded me more of math than computer science—relying on the board and notes instead of practical setup. I learned much from school, but at home I watched Linux commands while watching movies, finding it more engaging. There are three network topics covered: counting addresses, building a network in Cisco Packet Tracer, and designing a network in GNS. A classmate asked about routers, and I explained they connect computers and can amplify Wi-Fi signals. I’m curious to learn more about these concepts but feel overwhelmed by the complexity of the material. Many classmates grasp network ideas only briefly, and I struggle to understand what we’re discussing in class compared to what I see online.
The teacher is making mistakes. A router connects various devices and subnets. A switch handles packets inside the same VLAN or broadcast area, and it also sends and receives packets.
