- Speed: Most say cable is faster than DSL, but it doesn't always win in real-world use-Security: Different security models, but both offer adequate security that meets the needs of most users-Popularity: Cable is more popular but DSL is catching up-Customer Satisfaction: DSL customers are happier.TM is the Data Link layer protocol typically used over the DSL layer 1 connection from the CPE that's terminated at the DSLAM. After that, the DSLAM switches the data over an ATM network to an aggregation router, a layer 3 device where the subscriber's IP connection then expires.
A neural signal is another way of characterizing the electrochemical message that neurons send to each other. When a neuron receives sufficient stimulation in the form of EPSPs, voltage-gated ion channels open, and a signal is sent down the axon to the axon terminal. That is the electrical part of the message.
Figure 2:1 The neuron,or nerve cell, is the functional unit of the nervous system. The neurons has proceses called dendrites that receive signals and an axon that transmits signals to another neuron.The cell body, also called the soma, is the metabolic center of the neuron.. Communication between neurons is the foundation for brain function. Understanding how neurotransmission occurs is crucial to understanding how the brain processes and integrates information. Interruption of neural communication causes changes in cognitive processes and behavior.
