What is 'attenuation' in the context of network cables?

The increase in signal strength
The loss of signal integrity over distance
The amplification of weak signals
The speed of data transmission

The correct answer is: The loss of signal integrity over distance

Attenuation refers to the reduction in signal strength as it travels through a medium, such as a network cable. In networking, this loss of signal integrity over distance is crucial to understand because it can significantly impact the performance and reliability of data transmission. As the signal travels further from its source, factors such as resistance, cable quality, and external interference can cause the signal to weaken. This phenomenon makes it essential to consider attenuation when designing and installing network systems, as excessive attenuation can lead to data loss, slower speeds, and increased error rates. Proper cable selection, signal boosting, and repeating technologies can help mitigate the effects of attenuation, ensuring that the quality of the communication remains high over the required distances.
