014.01.64.1. Explain the main differences between wired and wireless Ethernet networks, focusing on the components in the physical layer that distinguish them. How does the Linux kernel handle communication with wireless network interfaces compared to wired interfaces?
This question assesses the candidate's understanding of the distinctions between wired and wireless networks, particularly in terms of physical layer components. It also evaluates their knowledge of how the Linux kernel interacts with wireless interfaces compared to wired ones.
The main difference between wired and wireless networks lies in the physical layer which includes components such as frequencies, network IDs, and security features. Unlike wired network hardware, which is good at adjusting to nuances in the physical setup without much fuss, wireless network configuration is much more open ended. To get a wireless network interface working properly, Linux needs additional configuration tools.
