The English word eavesdrop can be traced back as the origin of eavesdropping. Eavesdropping is listening to another person's conversations. This can be used as a way to get information about a person’s personal life. It is much easier to eavesdrop on IP-based calls rather than TDM.

Eavesdropping is a method where someone listens to conversations, thereby gaining information about the subject. Although they don't usually realize they are being listened too, they might not be aware of what they are doing. The person eavesdropping could be a stranger or have a specific purpose to listen to conversations.
Eavesdropping refers to a method of social networking hacking that intercepts legitimate wireless communications taking place in open space. An attacker might embed an invisible Eve in a nearby device. Because Eve has the same operating frequency as Bob, the attacker will be able intercept Alice's communications.
It is easier to perform with IP-based calls than TDM-based calls
TDM-based and IP-based calls have different transmission technologies. TDM calls use traditional phone service, but IP-based call uses IP networks to transmit voice. TDM-based calls can be eavesdropped on much easier than IP-based ones. Although IP-based calls are less secure, they are still cheaper. VoIP has many advantages, including lower operating expenses, higher call quality, and lower access charges.
IP telephony uses new logical network elements and protocols to carry voice calls. These new elements are responsible for call management, routing, and storing call information. They also enable new business scenarios. The three most basic business scenarios that IP telephony can be used for are:

How does your brain control the functions within your body?
To ensure that they work together, messages are sent by the brain to other organs. Everything in your body is controlled and managed by your brain. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain is made of billions, or neurons, of nerve cells. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Each neuron is covered by a cell membrane. Inside the membrane are channels that allow ions such as sodium and potassium to enter and leave the cell. The neuron fires when there is ion movement.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. As a result, second neuron fires as well.
Neurotransmitter production occurs when a neuron in the presynaptic receives an impulsive signal from another. An impulse travels along a synapse that connects the two neurons. The transmitter binds to receptors on the postsynaptic neuron, triggering the firing of the postsynaptic neuron.
They are vital for the communication between nerve cells. They coordinate brain activity among different parts.
