The term that describes the problem of signals weakening as they travel across media is "attenuation." Attenuation refers to the reduction in strength or intensity of a signal as it propagates through a medium, such as fiber optic cables, air, or electrical circuits. This phenomenon can occur due to various factors, including absorption, scattering, and dispersion, impacting the quality and clarity of the transmitted information.

Why stop signals are red in colour?
Stop signals are red in color primarily because red is universally associated with danger and the need to halt. This color stands out clearly against most backgrounds, ensuring high visibility and quick recognition. Additionally, red light has a longer wavelength, which allows it to be seen from greater distances, making it effective for alerting drivers and pedestrians to stop. The consistency of using red for stop signals also helps reinforce the message across different regions and cultures.
What is purpose of terminator on bus topology?
In a bus topology, the purpose of a terminator is to absorb signals at both ends of the bus cable, preventing them from bouncing back and causing network interference. Without terminators, signals could reflect back along the bus, leading to data collisions and communication errors. By ensuring proper signal termination, terminators help maintain the integrity of data transmission across the network.
What form of communication did incas use?
The Incas used a system of communication known as "quipu," which consisted of colored knotted strings to convey information and record data, such as census figures and tribute payments. They also relied on a network of runners called "chasquis" who delivered messages across their vast empire using a relay system. Additionally, visual signals, such as smoke signals and fires, were used to transmit urgent messages over long distances.
What term best describes the linking of the world's nations by fast communications transportation and trade?
The term that best describes the linking of the world's nations by fast communications, transportation, and trade is "globalization." Globalization refers to the increasing interconnectedness and interdependence of economies, cultures, and populations across the globe, facilitated by advancements in technology and infrastructure. This process has led to the integration of markets and the exchange of ideas, goods, and services on an unprecedented scale.
Does not get your point across means?
It means that you are unable to make the listener understand what you are trying to say. Perhaps you speak too vaguely or ramble off topic or possibly the person you are speaking to has a problem listening or understanding.

Which of the following terms describes the spread of influenza across Europe after the war?

What is a device that translates computer signals to analog signals suitable for sending across phone lines?
A modem. Short for MOdulate-DEModulate.
Which term describes describes the difference in the concentration of a substance across a cells membrane?
This is called the osmotic gradient.
What is a synapse in a simple reflex action?
A synapse in a simple reflex action is a junction between two neurons where signals are transmitted. In a reflex action, when a stimulus triggers a sensory neuron, it sends a signal across a synapse to a motor neuron, which then causes a rapid response from a muscle or gland.
