What is the greatest limitation of a wired system?

The greatest limitation of a wired system is primarily related to cable length. Wired systems often have specific maximum distances over which the signal can effectively travel without significant degradation. This limitation is particularly evident in types of cables, such as Ethernet, where the maximum effective length for maintaining signal integrity is generally around 100 meters. Beyond this distance, signals can weaken, leading to potential data loss, slower speeds, or complete communication failure.

In contrast, while Bluetooth interoperability and bandwidth are important considerations for certain applications, they do not directly pertain to the inherent limitations of wired connections. Similarly, the type of internet can affect performance but isn't a limitation unique to wired systems. Hence, cable length is the most critical factor when discussing the constraints of wired systems, as it directly impacts the overall functionality and reliability of the network infrastructure.
